Short-Term Waiver/Remission 
The short-term waiver of an open claim means that the entitlement due is not pursued further. The difference between a short-term waiver and a remission is the following: with a short-term waiver, the entitlement itself is not waived, whereas this is the case with a remission.
The prerequisites for using short-term waivers and remissions are defined by law.
Both the short-term waivers/remissions and reversals of short-term waivers refer to an original document (FI document). For short-term waivers/remissions , this FI document is a component of a posted acceptance request that has not yet been paid. For the reversal of a short-term waiver or remission, it is a posted short-term waiver or a posted remission.
You can use this function either to process a single FI document (individual short-term waiver) or several due dates for a subledger account (mass short-term waiver or mass remission). During mass processing, FI documents are not grouped together – this is sometimes the case with mass deferrals. The documents are then processed individually instead, by entering the invoice reference, and then saved in the database.
If you want to process documents with different currencies at the same time during mass processing, the data saved to the database may be inconsistent. In this is the case, the program only executes the short-term waiver/remission in the local currency.
A short-term waiver and remission functions as an acceptance request. If you enter a short-term waiver (a remission), the system copies the original document specified and creates the short-term waiver (the remission). This is saved in the system as a parked document. The short-term waiver (the remission) has the opposite +/- sign to the original item.
The parked document must undergo an approval procedure like a “normal” acceptance request. The posting can take place after the short-term waiver (remission) has been approved.
Note
As of 4.01A, it is only possible to waive a partial amount of an acceptance request.
Short-term waivers and remissions are cleared automatically when they are posted. The system clears the original document (outgoing payment/acceptance request or the posted down payment) with the short-term waiver or remission. If more short-term waivers refer to the original document, these are also considered and cleared. Of course, documents are only cleared automatically when the balance between the original document and the document(s) that refer to it is 0 in the company code currency.
