I use transaction F-44 to Settle the Invoice with the Advance payment and the balance about i want to remain as a payable amount. therefore I use the option of " res. item" in F-44. The issue i have is when i use the function the remaining about (payable ) is recorded with the document type " AB" but I want it to be saved a " RE" or 'KR" as invoice document type. how can i make the change?
