——————-
1. What is Workflow Background Engine?
The Background Engine is a PL/SQL procedure. The Background Engine checks for and executes any deferred or timed out activities that satisfy the arguments of the procedure at the time the procedure is invoked. If new activities are deferred or timed out after the initiation of the current Background Engine, the procedure will check one more time for any new activities to execute prior to ending. The procedure ends once all matching activities are executed.
 2. How the Background Engine is called?
Following is the Background Engine API which takes the mentioned parameters. WF_ENGINE.BACKGROUND( itemtype        in varchar2,
minthreshold    in number default null,
maxthreshold    in number default null,
process_deferred    in boolean default TRUE,
process_timeout    in boolean default TRUE)

3. How to Run the Background Engine from Oracle Applications?
Submit the Workflow Background Process Concurrent Program through
Navigate > Sysadmin > Request > Run
Item Type – Select the appropriate Item Type (say PO Approval)
Min and Max tershould – (specify 0 to 100 or you can leave it blank)
Defered = Yes (so that all defered activities are processed)
Timed out=Yes (so that all timedout activities are processed)

4. How to Run the Background Engine from SQL*Plus?
From SQL Prompt run the following command
SQL> EXEC WF_ENGINE.BACKGROUND
or from unix prompt
$ $FND_TOP/Admin/Sql/wfbkg.sql

5. Why run the Background Engine?
WF Engine does not handle all the activities. For the reasons like Timed Out, Defered or sometimes errored activities will be forwared to Workflow Background Engine. If that time the Workflow Background is not running then these process will be stuck in process only. Unless you start the Background these will not be processed. Even if you start the background engine with Defered = No and Timedout = No then also these will not be processed.
 6. Is it necessary to schedule the Background Engine?
In continuation to the above answer to to the Question 5, Workflow Background Engine will process the activities only which are forwarded by the Workflow Engine for reasons like timed out, defered etc. Once these activities are processed, the Workflow Background Engine goes down. You need to start the Workflow Background Engine again for any new activities which are forwarded. Therefore, it is usually recommended to schedule the Workflow Background Engine periodically especially for the Item Types such as PO Approval etc..

Data flow for Order-to-Cash cycle

Data flow for Order-to-Cash cycle  
Hello friends, here we are having one of the contribution from “Devendra Gulve” , very precise and useful explaination on O2C cycle. hope this be helpful to you.
For more details please visit http://functionalguy.blogspot.com
 
1. Order Entry
This is first stage, When the order is entered in the system, it creates a record in order headers and Order Lines table.
  • Enter header details: Once you enter details on the order header and save it or move it to lines, record goes to one table oe_order_headers_all
    • No record exists in any other table for this order till now.
  • Enter Line details for this order: Enter different item numbers, quantity and other details in line tab. When the record gets saved, it goes to one table. Order header details will be linked with line details by order HEADER_ID.
2. Order Booking
This is next stage, when Order is booked then the Flow status changed from Entered to Booked. At this stage, these below table get affected.
  • oe_order_headers_alL
  • oe_order_lines_all
  • wsh_delivery_details
  • wsh_delivery_assignments
*In shipping transaction form order status remains “Ready to Release”.
At the same time, Demand interface program runs in background and insert into inventory tables mtl_demand.
3. Reservation
This step is required for doing reservations SCHEDULE ORDER PROGRAM runs in the background and quantities are reserved. Once this program get successfully get completed, the mtl_demand and mtl_reservations table get updated.
4. Pick Release
Pick Release is the process of putting reservation on on-hand quantity available in the inventory and pick them for particular sales order.
Pick release can be done from ‘Release Sales Order’ form or ‘Pick release SRS’ program can be scheduled in background. In both of these cases all lines of the order gets pick released depending on the Picking rule used. If specific line/s needs to be pick release it can be done from ‘Shipping Transaction form. For this case Pick Release is done from ‘Release Sales Order’ form with Pick Confirm=NO.
Once pick release is done these are the tables get affected:
  • If step 3 is not done then MTL_RESERVATIONS gets updated now.
  • wsh_new_deliveries
  • wsh_delivery_assignments
  • wsh_delivery_details
  • MTL_TXN_REQUEST_HEADERS
  • MTL_TXN_REQUEST_LINES
  • Mtl_material_transactions_temp
  • MTL_SERIAL_NUMBERS_TEMP
  • MTL_SERIAL_NUMBERS
*In shipping transaction form order status remains “Released to Warehouse” and all the material still remains in source sub-inventory. We need to do Move Order Transaction for this order. Till this no material transaction has been posted to MTL_MATERIAL_TRANSACTIONS
5. Pick Confirm/ Move Order Transaction
Items are transferred from source sub-inventory to staging Sub-inventory. Here material transaction occurs.
Order line status becomes ‘Picked’ on Sales Order and ‘Staged/Pick Confirmed’ on Shipping Transaction Form.
  • MTL_MATERIAL_TRANSACTIONS_TEMP
  • oe_order_lines_all
  • MTL_MATERIAL_TRANSACTIONS
  • mtl_transaction_accounts
  • wsh_delivery_details
  • wsh_delivery_assignments
  • MTL_ONHAND_QUANTITIES
  • MTL_SERIAL_NUMBERS_TEMP
  • MTL_SERIAL_NUMBERS
* This step can be eliminated if we set Pick Confirm=YES at the time of Pick Release 
6. Ship Confirm
Here ship confirm interface program runs in background. Data removed from wsh_new_deliveries. 
The items on the delivery gets shipped to customer at this stage.
  • oe_order_lines_all
  • wsh_delivery_details
  • WSH_SERIAL_NUMBERS
  • mtl_transaction_interface
  • mtl_material_TRANSACTIONS
  • mtl_transaction_accounts
  • mtl_demand, MTL_reservations
  • MTL_ONHAND_QUANTITIES
  • MTL_SERIAL_NUMBERS_TEMP
  • MTL_SERIAL_NUMBERS
7. Enter Invoice 
After shipping the order the order lines gets eligible to get transferred to RA_INTERFACE_LINES_ALL. Workflow background engine picks those records and post it to RA_INTERFACE_LINES_ALL. This is also called Receivables interface, that mean information moved to accounting area for invoicing details. Invoicing workflow activity transfers shipped item information to Oracle Receivables. At the same time records also goes in the table RA_INTERFACE_SALESCREDITS_ALL which hold details of sales credit for the particular order.
ra_interface_lines_all (interface table into which the data is transferred from order management) Then Auto-invoice program imports data from this table which get affected into this stage are receivables base table. At the same time records goes in ra_customer_trx_all and ra_customer_trx_lines_all
8. Complete Line
In this stage order line level table get updated with Flow status and open flag.
oe_order_lines_all
9. Close Order
This is last step of Order Processing. In this stage only oe_order_lines_all table get updated. These are the table get affected in this step.

oe_order_lines_all
oe_order_HEADERS_all

Useful AR Tables Informations

here is some of quite commonly used AR ( receivables )tables and their usage. There are many other tables also in AR but here i am putting only few commonly used tables. for other table if needed we can dig furthur. Let go through below article and let me know if it useful.
1- RA_CUSTOMER_TRX_ALL
2- RA_CUSTOMER_TRX_LINES_ALL
3- RA_CUST_TRX_LINE_GL_DIST_ALL
4- AR_PAYMENT_SCHEDULES_ALL
5- AR_RECEIVABLES_TRX_ALL
6- AR_RECEIVABLE_APPLICATIONS_ALL
RA_CUSTOMER_TRX_ALL
This table stores invoice, debit memo, commitment, and credit memo header information. Each row includes general invoice information such as customer, transaction type, and printing instructions. You need one row for each invoice, debit memo, commitment, and credit memo you create in Oracle Receivables. Invoices, debit memos, credit memos, and commitments are all distinguished by their transaction types stored in RA_CUST_TRX_TYPES_ALL. If you entered a credit memo, PREVIOUS_CUSTOMER_TRX_ID stores the customer transaction identifier of the invoice you credited. In the case of on account credits, which are not related to any invoice at creation, PREVIOUS_CUSTOMER_TRX_ID is null. If you created an invoice against a commitment, Oracle Receivables stores the customer transaction identifier of the commitment in INITIAL_CUSTOMER_TRX_ID, otherwise it is null. COMPLETE_FLAG stores ’Y’ for Yes and ’N’ for No to indicate if your invoice is complete. When you complete an invoice, Oracle Receivables creates your payment schedules and updates any commitments against this invoice. Before an invoice can be completed, it must have at least one invoice line, revenue records must exist for each line and add up to the line amount, and a sales tax record must exist for each line.
Required Columns:
SOLD_TO_CUSTOMER_ID,
SOLD_TO_SITE_USE_ID,
BILL_TO_CUSTOMER_ID,
BILL_TO_SITE_USE_ID,
SHIP_TO_SITE_USE_ID,
PRINTING_OPTION,
PRINTING_PENDING,
TERM_ID,
REMIT_TO_ADDRESS_ID,
PRIMARY_SALES_REP_ID, and
INVOICE_CURRENCY_CODE
are required even though they are null allowed. The primary key for this table is CUSTOMER_TRX_ID.
RA_CUSTOMER_TRX_LINES_ALL
This table stores information about invoice, debit memo, credit memo, and commitment lines. For example, an invoice can have one line for Product A and another line for Product B. You need one row for each line. Invoice, debit memo, credit memo, and commitment lines are distinguished by the transaction type of the corresponding RA_CUSTOMER_TRX_ALL record.Also, credit memos are required to have a value in PREVIOUS_CUSTOMER_TRX_LINE_ID, except on account credits which are not related to specific invoices/invoice lines at creation time, will not have values in this column. QUANTITY_ORDERED stores the amount of product ordered. QUANTITY_INVOICED stores the amount of product invoiced. For invoices entered through the window, QUANTITY_ORDERED and QUANTITY_INVOICED must be the same. For invoices imported through AutoInvoice, QUANTITY_ORDERED and QUANTITY_INVOICED can be different. If you enter a credit memo, QUANTITY_CREDITED stores the amount of product credited. UOM_CODE stores the unit of measure code as defined in MTL_UNITS_OF_MEASURE. UNIT_STANDARD_PRICE stores the list price per unit for this transaction line. UNIT_SELLING_PRICE stores the selling price per unit for this transaction line. For transactions imported through AutoInvoice, UNIT_STANDARD_PRICE and UNIT_SELLING_PRICE can be different. DESCRIPTION, TAXING_RULE, QUANTITY_ORDERED, UNIT_STANDARD_PRICE,UOM_CODE, and UNIT_SELLING_PRICE are required even though they are null allowed. LINE_TYPE differentiates between the different types of lines that are stored in this table. LINE points to regular invoice lines that normally refer to an item. TAX signifies that this is a tax line. The column LINK_TO_CUST_TRX_LINE_ID references another row in this table that is the invoice line associated with the row of type TAX. FREIGHT works the same way as TAX but there you can have at most one FREIGHT type l ine per invoice line of type LINE. You can also have one line of type FREIGHT that has a null LINK_TO_CUST_TRX_LINE_ID (and this is referred to as header level freight). CHARGES works just like the LINE type. A line_type of ’CB’ is created for a Chargeback line. For every row in this table that belongs to a complete transaction (where RA_CUSTOMER_TRX.COMPLETE_FLAG = Y), there must be at least one row in the table RA_CUST_TRX_LINE_GL_DIST (which stores accounting information), even for non–postable transactions. The primary key for this table is CUSTOMER_TRX_LINE_ID.
RA_CUST_TRX_LINE_GL_DIST_ALL
This table stores the accounting records for revenue, unearned revenue and unbilled receivables for each invoice or credit memo line. Each row includes the GL account and the amount of the accounting entry. The AMOUNT column in this table is required even though it is null allowed. You need one row for each accounting distribution. You must have at least one (but you can have multiple) accounting distributions for each invoice or credit memo line. Oracle Receivables uses this information to post the proper amounts to your general ledger. If your invoice or credit memo has a transaction type where Post to GL is set to No, Oracle Receivables assigns Null to GL_DATE. If your AutoAccounting is unable to complete your general ledger default accounts using the AutoAccounting rules you define, incomplete general ledger accounts are stored in CONCATENATED_SEGMENTS. If you are importing a transaction through AutoInvoice and the general ledger date of your transaction is in a closed accounting period, AutoInvoice uses the general ledger date of the first open accounting period and stores the original general ledger date in ORIGINAL_GL_DATE. ACCOUNT_CLASS defines which type of distribution row you are on. The ACCOUNT_CLASS REC represents the receivable account and is for the total amount of the invoice. There can be at most two REC rows. One that has a ACCOUNT_SET_FLAG set to Y and the other has ACCOUNT_SET_FLAG set to N. Use LATEST_REC_FLAG to join to the later of the two rows. ACCOUNT_SET_FLAG is Y if this row is part of an account set. An account set is a set of rows that represent a model distribution. Account sets are used for invoices with rules. The rows represent how the actual distribution rows should be created and what percentage of the actual distribution should be allocated to each account. For invoices with rules, the distributions are not created when the invoice is initially created. Instead, the invoices are created when the Revenue Recognition program is run. The primary key for this table is CUST_TRX_LINE_GL_DIST_ID.
AR_PAYMENT_SCHEDULES_ALL
This table stores all transactions except adjustments and miscellaneous cash receipts. Oracle Receivables updates this table when activity occurs against an invoice, debit memo, chargeback, credit memo, on account credit, or receipt. Oracle Receivables groups different transactions bythe column CLASS. These classes include invoice (INV), debit memos(DM), guarantees (GUAR), credit memos (CM), deposits (DEP),chargebacks (CB), and receipts (PMT). Transaction classes determine which columns in this table Oracle Receivables updates when a transaction occurs, and whether a transaction relates to either the RA_CUSTOMER_TRX_ALL table or the AR_CASH_RECEIPTS_ALLtable. AR_PAYMENT_SCHEDULES_ALL joins to the RA_CUSTOMER_TRX_ALL table for non–payment transaction entries such as the creation of credit memos, debit memos, invoices, chargebacks, or deposits. AR_PAYMENT_SCHEDULES_ALL uses the foreign key CUSTOMER_TRX_ID to join to the RA_CUSTOMER_TRX_ALL table for these transactions. AR_PAYMENT_SCHEDULES_ALL joins to the AR_CASH_RECEIPTS_ALL table for invoice–related payment transactions using the foreign key CASH_RECEIPT_ID. When a receiptis applied, Oracle Receivables updates AMOUNT_APPLIED, STATUS and AMOUNT_DUE_REMAINING. STATUS changes from ’OP’ to ’CL’for any transaction that has an AMOUNT_DUE_REMAINING value of 0(Zero). ACTUAL_DATE_CLOSED and GL_DATE_CLOSED are populated with the date of the latest transaction. For a receipt, the amount due remaining includes on account and unapplied amounts. Oracle Receivables stores debit items such as invoices, debit memos, chargebacks, deposits, and guarantees as positive numbers in the AMOUNT_DUE_REMAINING and AMOUNT_DUE_ORIGINAL columns. Credit items such as credit memos and receipts are stored as negative numbers. In Release 10, receipts can be confirmed or not confirmed as designated by the CONFIRMED_FLAG column. The sum of the AMOUNT_DUE_REMAINING column for a customer for all confirmed payment schedules reflects the current customer balance. If this amount is negative, then this column indicates the credit balance amount currently available for this customer. For invoices with split terms, one record is created in RA_CUSTOMER_TRX_ALL and one record is stored in AR_PAYMENT_SCHEDULES_ALL for each installment. In AR_PAYMENT_SCHEDULES_ALL, DUE_DATE and AMOUNT_DUE_REMAINING can differ for each installment of a split term invoice. Each installment is differentiated by the TERMS_SEQUENCE_NUMBER column.
If you create a debit memo reversal when you reverse a receipt, Oracle Receivables creates a new payment schedule record for the debit memo and fills in REVERSED_CASH_RECEIPT_ID with the CASH_RECEIPT_ID of the receipt that was reversed. Oracle Receivables creates a new payment schedule record when you create a chargeback in the Receipts window. ASSOCIATED_CASH_RECEIPT_ID is the cash receipt of the payment you entered when you created the chargeback in this window. GL_DATE_CLOSED indicates the general ledger date on which your transaction was closed.
This column identifies which transactions Oracle Receivables selects when it displays current and overdue debit items in the aging reports. The aging reports also utilize the current balances in AMOUNT_DUE_REMAINING to display outstanding amounts for current and overdue debit items. ACTUAL_DATE_CLOSED gives the date on which you applied a payment or credit to an open transaction that set AMOUNT_DUE_REMAINING to 0 for that transaction. Oracle Receivables uses ACTUAL_DATE_CLOSED to determine which transactions to include when you print statements. The primary key for this table is PAYMENT_SCHEDULE_ID, which identifies the transaction that created the row.

RA_CUSTOMER_TRX_ALL
This table stores invoice, debit memo, commitment, and credit memo header information. Each row includes general invoice information such as customer, transaction type, and printing instructions. You need one row for each invoice, debit memo, commitment, and credit memo you create in Oracle Receivables. Invoices, debit memos, credit memos, and commitments are all distinguished by their transaction types stored in RA_CUST_TRX_TYPES_ALL. If you entered a credit memo, PREVIOUS_CUSTOMER_TRX_ID stores the customer transaction identifier of the invoice you credited. In the case of on account credits, which are not related to any invoice at creation, PREVIOUS_CUSTOMER_TRX_ID is null. If you created an invoice against a commitment, Oracle Receivables stores the customer transaction identifier of the commitment in INITIAL_CUSTOMER_TRX_ID, otherwise it is null. COMPLETE_FLAG stores ’Y’ for Yes and ’N’ for No to indicate if your invoice is complete. When you complete an invoice, Oracle Receivables creates your payment schedules and updates any commitments against this invoice. Before an invoice can be completed, it must have at least one invoice line, revenue records must exist for each line and add up to the line amount, and a sales tax record must exist for each line.
Required Columns:
SOLD_TO_CUSTOMER_ID,
SOLD_TO_SITE_USE_ID,
BILL_TO_CUSTOMER_ID,
BILL_TO_SITE_USE_ID,
SHIP_TO_SITE_USE_ID,
PRINTING_OPTION,
PRINTING_PENDING,
TERM_ID,
REMIT_TO_ADDRESS_ID,
PRIMARY_SALES_REP_ID, and
INVOICE_CURRENCY_CODE
are required even though they are null allowed. The primary key for this table is CUSTOMER_TRX_ID.
RA_CUSTOMER_TRX_LINES_ALL
This table stores information about invoice, debit memo, credit memo, and commitment lines. For example, an invoice can have one line for Product A and another line for Product B. You need one row for each line. Invoice, debit memo, credit memo, and commitment lines are distinguished by the transaction type of the corresponding RA_CUSTOMER_TRX_ALL record.Also, credit memos are required to have a value in PREVIOUS_CUSTOMER_TRX_LINE_ID, except on account credits which are not related to specific invoices/invoice lines at creation time, will not have values in this column. QUANTITY_ORDERED stores the amount of product ordered. QUANTITY_INVOICED stores the amount of product invoiced. For invoices entered through the window, QUANTITY_ORDERED and QUANTITY_INVOICED must be the same. For invoices imported through AutoInvoice, QUANTITY_ORDERED and QUANTITY_INVOICED can be different. If you enter a credit memo, QUANTITY_CREDITED stores the amount of product credited. UOM_CODE stores the unit of measure code as defined in MTL_UNITS_OF_MEASURE. UNIT_STANDARD_PRICE stores the list price per unit for this transaction line. UNIT_SELLING_PRICE stores the selling price per unit for this transaction line. For transactions imported through AutoInvoice, UNIT_STANDARD_PRICE and UNIT_SELLING_PRICE can be different. DESCRIPTION, TAXING_RULE, QUANTITY_ORDERED, UNIT_STANDARD_PRICE,UOM_CODE, and UNIT_SELLING_PRICE are required even though they are null allowed. LINE_TYPE differentiates between the different types of lines that are stored in this table. LINE points to regular invoice lines that normally refer to an item. TAX signifies that this is a tax line. The column LINK_TO_CUST_TRX_LINE_ID references another row in this table that is the invoice line associated with the row of type TAX. FREIGHT works the same way as TAX but there you can have at most one FREIGHT type l ine per invoice line of type LINE. You can also have one line of type FREIGHT that has a null LINK_TO_CUST_TRX_LINE_ID (and this is referred to as header level freight). CHARGES works just like the LINE type. A line_type of ’CB’ is created for a Chargeback line. For every row in this table that belongs to a complete transaction (where RA_CUSTOMER_TRX.COMPLETE_FLAG = Y), there must be at least one row in the table RA_CUST_TRX_LINE_GL_DIST (which stores accounting information), even for non–postable transactions. The primary key for this table is CUSTOMER_TRX_LINE_ID.
RA_CUST_TRX_LINE_GL_DIST_ALL
This table stores the accounting records for revenue, unearned revenue and unbilled receivables for each invoice or credit memo line. Each row includes the GL account and the amount of the accounting entry. The AMOUNT column in this table is required even though it is null allowed. You need one row for each accounting distribution. You must have at least one (but you can have multiple) accounting distributions for each invoice or credit memo line. Oracle Receivables uses this information to post the proper amounts to your general ledger. If your invoice or credit memo has a transaction type where Post to GL is set to No, Oracle Receivables assigns Null to GL_DATE. If your AutoAccounting is unable to complete your general ledger default accounts using the AutoAccounting rules you define, incomplete general ledger accounts are stored in CONCATENATED_SEGMENTS. If you are importing a transaction through AutoInvoice and the general ledger date of your transaction is in a closed accounting period, AutoInvoice uses the general ledger date of the first open accounting period and stores the original general ledger date in ORIGINAL_GL_DATE. ACCOUNT_CLASS defines which type of distribution row you are on. The ACCOUNT_CLASS REC represents the receivable account and is for the total amount of the invoice. There can be at most two REC rows. One that has a ACCOUNT_SET_FLAG set to Y and the other has ACCOUNT_SET_FLAG set to N. Use LATEST_REC_FLAG to join to the later of the two rows. ACCOUNT_SET_FLAG is Y if this row is part of an account set. An account set is a set of rows that represent a model distribution. Account sets are used for invoices with rules. The rows represent how the actual distribution rows should be created and what percentage of the actual distribution should be allocated to each account. For invoices with rules, the distributions are not created when the invoice is initially created. Instead, the invoices are created when the Revenue Recognition program is run. The primary key for this table is CUST_TRX_LINE_GL_DIST_ID.
AR_PAYMENT_SCHEDULES_ALL
This table stores all transactions except adjustments and miscellaneous cash receipts. Oracle Receivables updates this table when activity occurs against an invoice, debit memo, chargeback, credit memo, on account credit, or receipt. Oracle Receivables groups different transactions bythe column CLASS. These classes include invoice (INV), debit memos(DM), guarantees (GUAR), credit memos (CM), deposits (DEP),chargebacks (CB), and receipts (PMT). Transaction classes determine which columns in this table Oracle Receivables updates when a transaction occurs, and whether a transaction relates to either the RA_CUSTOMER_TRX_ALL table or the AR_CASH_RECEIPTS_ALLtable. AR_PAYMENT_SCHEDULES_ALL joins to the RA_CUSTOMER_TRX_ALL table for non–payment transaction entries such as the creation of credit memos, debit memos, invoices, chargebacks, or deposits. AR_PAYMENT_SCHEDULES_ALL uses the foreign key CUSTOMER_TRX_ID to join to the RA_CUSTOMER_TRX_ALL table for these transactions. AR_PAYMENT_SCHEDULES_ALL joins to the AR_CASH_RECEIPTS_ALL table for invoice–related payment transactions using the foreign key CASH_RECEIPT_ID. When a receiptis applied, Oracle Receivables updates AMOUNT_APPLIED, STATUS and AMOUNT_DUE_REMAINING. STATUS changes from ’OP’ to ’CL’for any transaction that has an AMOUNT_DUE_REMAINING value of 0(Zero). ACTUAL_DATE_CLOSED and GL_DATE_CLOSED are populated with the date of the latest transaction. For a receipt, the amount due remaining includes on account and unapplied amounts. Oracle Receivables stores debit items such as invoices, debit memos, chargebacks, deposits, and guarantees as positive numbers in the AMOUNT_DUE_REMAINING and AMOUNT_DUE_ORIGINAL columns. Credit items such as credit memos and receipts are stored as negative numbers. In Release 10, receipts can be confirmed or not confirmed as designated by the CONFIRMED_FLAG column. The sum of the AMOUNT_DUE_REMAINING column for a customer for all confirmed payment schedules reflects the current customer balance. If this amount is negative, then this column indicates the credit balance amount currently available for this customer. For invoices with split terms, one record is created in RA_CUSTOMER_TRX_ALL and one record is stored in AR_PAYMENT_SCHEDULES_ALL for each installment. In AR_PAYMENT_SCHEDULES_ALL, DUE_DATE and AMOUNT_DUE_REMAINING can differ for each installment of a split term invoice. Each installment is differentiated by the TERMS_SEQUENCE_NUMBER column.
If you create a debit memo reversal when you reverse a receipt, Oracle Receivables creates a new payment schedule record for the debit memo and fills in REVERSED_CASH_RECEIPT_ID with the CASH_RECEIPT_ID of the receipt that was reversed. Oracle Receivables creates a new payment schedule record when you create a chargeback in the Receipts window. ASSOCIATED_CASH_RECEIPT_ID is the cash receipt of the payment you entered when you created the chargeback in this window. GL_DATE_CLOSED indicates the general ledger date on which your transaction was closed.
This column identifies which transactions Oracle Receivables selects when it displays current and overdue debit items in the aging reports. The aging reports also utilize the current balances in AMOUNT_DUE_REMAINING to display outstanding amounts for current and overdue debit items. ACTUAL_DATE_CLOSED gives the date on which you applied a payment or credit to an open transaction that set AMOUNT_DUE_REMAINING to 0 for that transaction. Oracle Receivables uses ACTUAL_DATE_CLOSED to determine which transactions to include when you print statements. The primary key for this table is PAYMENT_SCHEDULE_ID, which identifies the transaction that created the row.

AR_RECEIVABLES_TRX_ALL
This table links accounting information with your Receivables Activities. Possible types of activities include Adjustment, Miscellaneous Cash, and Finance Charges. If your type is Miscellaneous Cash, you can associate either a distribution set or a standard accounting flexfield to your Receivables Activity. Oracle Receivables uses one row for each activity. You use your receivables activities to speed receipt entry and generate finance charges. The other types of activities that were valid in release 9 and no longer valid in Release 10 were converted (as part of the upgrade) such that the actual accounting flexfield CODE_COMBINATION_ID is stored in the table instead of the RECEIVABLES_TRX_ID. In Release 9, all of these references were in AR_BATCH_SOURCES; they are now in AR_RECEIPT_METHOD_ACCOUNTS_ALL. The primary key for this table is RECEIVABLES_TRX_ID.
AR_RECEIVABLE_APPLICATIONS_ALL
This table stores all accounting entries for your cash and credit memo applications. Each row includes the amount applied, status, and accounting flexfield information. Possible statuses of your applications include APP, UNAPP, ACC, and UNID. You use this information to determine the applications of your payments or credit memos. CONFIRMED_FLAG is a denormalization from AR_CASH_RECEIPTS_ALL.If the cash receipt is not confirmed, the applications of that receipt are not reflected in the payment schedule of the transaction it is applied against. There are two kinds of applications: CASH and CM (for credit memo applications). This is stored in the column APPLICATION_TYPE.
CASH applications represent applications of a cash receipt. When a cash receipt is initially created, a row is created in this table that has a status of UNAPP for the amount of the cash receipt. Each subsequent application creates two rows – one with a status of APP for the amount being applied to the invoice and one with status UNAPP for the negative of the amount being applied. Ifyou reverse a cash application, a row with status APP with the inverse amount of the original application (i.e. the negative of the original application amount) is created. The corresponding UNAPP rows is alsocreated which will have a positive amount (the same amount as the application being reversed). For example: UNAPP 100 creation of a$100 cash receipt APP 60 application of $60 of this cash receipt UNAPP –60 this row takes away (debits) unapplied APP –60 reversal of the $60 application UNAPP 60 this rows puts back(credits) unapplied The sum of the AMOUNT_APPLIED column for CASH applications should always equal the amount of the cash receipt. CM applications, on the other hand, do not have rows of status UNAPP. They only use rows with a status of APP. CASH_RECEIPT_ID stores the cash receipt identifier of the receipt you entered. Oracle Receivables concurrently creates a record of this receipt in the AR_CASH_RECEIPTS_ALL table.
This column is null for a credit memo application. CODE_COMBINATION_ID stores valid Accounting Flexfield segment value combinations that will be credited in the General Ledger when this application is posted. A negative value in AMOUNT_APPLIED becomes a debit. The STATUS of a receivable application determines which flexfield account Oracle Receivables uses. For example, if you enter a cash receipt of $500 as Unidentified, Oracle Receivables creates a record in theAR_RECEIVABLE_APPLICATIONS_ALL table with AMOUNT_APPLIED = 500 and STATUS = ’UNID’. Oracle Receivables uses the foreign key CODE_COMBINATION_ID to associate this payment with the Unidentified flexfield account. CUSTOMER_TRX_ID, CASH_RECEIPT_ID, and PAYMENT_SCHEDULE_ID identify the transaction that you are actually applying. APPLIED_CUSTOMER_TRX_ID and APPLIED_PAYMENT_SCHEDULE_ID identify the invoice or credit memo that receives the application. For example, if you apply a receipt against an invoice, Oracle Receivables creates a record in the AR_RECEIVABLE_APPLICATIONS_ALL table. The CASH_RECEIPT_ID and the PAYMENT_SCHEDULE_ID of this record identify the receipt you are applying. APPLIED_PAYMENT_SCHEDULE_ID and APPLIED_CUSTOMER_TRX_ID for this record belong to the invoice that is receiving the application. If you apply a credit memo against the invoice, Oracle Receivables creates a record in the AR_RECEIVABLE_APPLICATIONS_ALL table that has theCUSTOMER_TRX_ID and the PAYMENT_SCHEDULE_ID of the credit memo you are applying. The APPLIED_PAYMENT_SCHEDULE_ID and the APPLIED_CUSTOMER_TRX_ID of this record belong to the invoice that is receiving the application. If you combine an on account credit and a receipt, Oracle Receivables creates a record in the AR_RECEIVABLE_APPLICATIONS_ALL table.
The PAYMENT_SCHEDULE_ID and the CASH_RECEIPT_ID of this record identify the receipt. The APPLIED_PAYMENT_SCHEDULE_ID and the APPLIED_CUSTOMER_TRX_ID of this record identify the on account credit that you are combining with the receipt. The primary key for this table is RECEIVABLE_APPLICATION_ID, which uniquely identifies the transaction that created the row.
