Deferral Requests 
Special request that helps to map the Deferral of a receivable in the SAP system.
The deferral request is a request with request category 06.
As with requests, the deferral request is first saved as a parked document. The deferral document must undergo an approval procedure in the same way as a “normal” acceptance request, before it can be posted. There is more information on the general structure of requests here .
The deferral request relates to a source document (FI document). This FI document is part of a posted acceptance request that has not yet been paid. The (FI) document number of the source document is saved as the invoice reference.
The program automatically clears the open items from the original due date and the offsetting entry with the deferral request and its reversal.
When a deferral request is reversed, the system generates its own parked open item. An approval procedure for the reversal of the deferral is possible with this. For more information, see Reversing Deferral Requests .
For the deferral request, the G/L account specified in the Customizing of Funds Management in IMG activity Define Account Determination for Deferrals is also posted to. As soon as you have defined a G/L account, it is used in the deferral request and the corresponding reverse posting instead of the one defined in the account determination table.
If you generate interest items for a deferral, you can specify a revenue type or a commitment item to which this interest item should be posted. As such, the program posts the G/L account with what it determines from the IMG activity Define G/L Account Determination .
