Hello,
Maybe this will help... The code to generate a payment terms installment should only effect the Account Receivable Account and the Amount being posted with the correct Due Date. For example, you have an Invoice for 100,000.00. Your terms are 33% NET 30, 33% NET 60, Remainder NET 90 or 34%, total 100%. Upon posting the Original Invoice, the Posted Document Number was split into 3 Documents with a -1, -2 on the 2nd and 3rd document. The first was Document No. 12345 for 33,000.00, NET 30. Next was Document No. 12345-1, 33,000 NET 60, and last Document was 12345-2 34,000 NET 90. All with the same Document Date just different Payment Terms update.
Hope this helps.
Thanks,
Steve
