Receipt application window "Document Number" column does not appear LOV

Dear all,

In R12.1.3 instance,

1. Setup the document sequence once AR invoice is generated he Document number will be generated automatically along with Transaction number.

2  In Receipt application screen while applying the receipt usually we will get the transaction number in LOV in Apply to field

3. Add a field using show filed option and inserted a column "Document Number"
4. We are looking that the document number field also should appear as mandatory with LOV, so users can apply the receipt using with document number.

Found a 11i Bug 836660 - APPLICATION RECEIPT SCREEN DOES NOT SHOW DOCUMENT NUMBER IN FOLDER
