The SAPF103 program reads open items in a customer account and transfers any doubtful receivables to a special general ledger account if the balance is greater than zero and the transfer posting deadline has been reached. It clears the original item and posts a new item with a specified general ledger indicator. For example, if an invoice is due longer than the transfer posting period, the program will select the item and post it to the special general ledger account. The baseline date field helps determine the amount of provision, and the original invoice number can be found in the assignment field. Any credit memos are also transferred to reduce previously made provisions for doubtful receivables.
