Dear Experts,

I need your help for solving this issue.

Asper as cline requirement,we write a program for vendor pre payment process.In this programe we make a payment for single vendor based on profit center and posting dates.In the program first screen give inputs like dates,Vendor,profit center,house bank and check lot.When we execute,its shown all due date documents.In this stage we give interest as manual,go to next screen ,its shown interest calculation amount and due days.After that its calling F-58.

Issue is  in F-58 all documents are not picked, I checked payment terms and interest calculation.

I will be very thankful for your help.
