Retrieving ISS Withholding Information

The system retrieves ISS withholding information differently when a voucher is matched to a purchase order than when no purchase order is associated with the voucher. If the voucher is matched to a purchase order, the system retrieves the ISS withholding information from the Purchase Order ISS Tax Information table (F76B705). When you enter a purchase order, the F76B705 table is populated with the service type code, city code, and whether ISS applies to the transaction.

If the voucher is not matched to a purchase order, the system uses the values in the supplier address book record and the processing options to determine the values used for processing ISS withholding.
