I had find all the forums but couldn't find a similar one. Please help.
For F-28 Post Incoming Payments, user will need to select AR invoices (field Reference) one by one in order to clear the outstanding invoices.
User can use the additional selections --> reference and input all the values. However, there are thousands of invoices to be inputted. The screen allows for 16 input values each time.
Is there any user exit for this "additional selections" screen? So that user can upload all the values from files when clicking one button from screen.
