R12.2.4 Functionality

Payment Accounting is when Payment Clears 

1.Made the Invoice 
2.Validate the Invoice 
3.Made the Payment 
4.Run the Create Accounting Program (Invoice Accounted to Yes & Payment Accounting to Processed) 
5.Clears the Payment from Cash Management (Payment goes on Accounting Partial) 
6.Run the Create Accounting again (Payment Accounting is Processed) 


R12.0.6 Functionality
Payment Accounting is when Payment Clears 

1.Made the Invoice 
2.Validate the Invoice 
3.Made the Payment 
4.Run the Create Accounting Program (Invoice Accounted to Yes & Payment Accounting to Unprocessed) 
5.Clears the Payment from Cash Management (Payment Accounting is still Unprocessed) 
6.Run the Create Accounting again (Payment Accounting is Processed) 

As you can see above there is a difference in Accounting Status Starts from step 4 in both 12.0.6 and 12.2.4 Functionalities. 
Is this is a Standard Functionality in R12.2.4 that the Payment Accounting is Processed two times One Accounting through Program after Payment and Second Accounting after Clearing?

--------------------------------------------------------------------------------------------------------------------------

Initially system used to work as below 
R12.0.6 

1- Create and Account for an Invoice 
2- Pay in Full 
3- Run Create Accounting 

In this case, the Payment Created remains in status U/U (unprocessed) in xla_events 

This is modified in the bug 9245156 to work as below 

R12.2.4

1- Create and Account for an Invoice 
2- Pay in Full 
3-Run Create Accounting 

Now system will show the Payment is accounted and stamp Payment Created status N/P 

This mainly to avoid the Payment showing in period close exception report before clearing the Payment. 

This is modified in file apslappb.pls and system is working as intended in current version of application 

This changes are done due to Period Closing Purpose 

Hope this clarifies
