'Invoice Advance Offer' is processed using IATPOP transaction.

Processing can be done manually, semi-STP or full STP.  When processing is done manually, the user will select the “buyer” and the “supplier” from the database. Pairing information as defined in transaction Maintain Pairing Buyer/Supplier such as the “Maximum Finance Percentage” will automatically be loaded.

Then the “Finance Base Documents” are entered in the respective panel. The “Total Invoice Amount” is calculated automatically and the “Advance Amount” is defaulted into the respective fields. The defaulting of the “Advance Amount” takes into consideration that it may not be higher than the “Maximum Finance Percentage”. The user may overwrite the defaulted “Advance Amount” with a lower amount.
