GL_DATE in RECEIPTS Form / AR_RECEIVABLE_APPLICATIONS_ALL

Hello,

 

Can anyone please help me to resolve the following issue using CUSTOM.pll?

 

1) Receipt is created in 01-Jan-11 (Receipt Date), GL_DATE = 01-Jan-11. No customer attached to this receipt. So this receipt status is unidentified receipt.

2) In 05-Feb-11 (Jan Period is still open), user adding the customer information to the receipt created in step 1. Now the receipt status become unapplied from unidentified. After saving the changes, Oracle Standard form calling some function and inserting the 2 new rows (UNID, UNAPP) in AR_RECEIVABLE_APPLICATIONS_ALL Table with Jan GL_DATE, i.e. 01-jan-11.

Can some one help me how to force the oracle using CUSTOM.pll to use the current GL_DATE instead of prior period GL_DATE.
