Deferrals 
When a receivable is deferred, the payment due date is postponed to a later date. Whether a receivable can be deferred, depends on whether it fulfills the relevant legal requirements.
Deferrals are posted to a separate G/L account, which you define in the Customizing of Funds Management Government . For more information, see the IMG in the activities for Define Account Determination for Deferrals .
If you want to calculate deferral interest, you have to define an interest formula in the Customizing of Funds Management Government .For more information, see the IMG activity Define Interest Calculation .
In a deferral transaction, you can either defer a single FI document (individual deferral) or several due dates for a subledger account (mass deferral). In the case of a mass deferral, the program saves the documents created by the deferral in the system with a request number.The system can also save documents without a request number for individual deferrals, this is however not the case for mass deferrals.
The program copies the default values for personal data and FM account assignment from the source document to the entry mask of the deferral request. Other data, such as the CO account assignment or the number of the earmarked funds document, are not copied. The program only takes foreign currencies into consideration if all the selected documents have the same foreign currency.
This function refers to the whole deferral request and not to single items of the request.The installment calculation procedure you choose to generate due dates becomes effective if there are different documents with the same due date in one deferral request. During the sequential procedure all documents with the same due date are processed one after another, whereas during the proportional procedure the documents are processed proportionally.
When you enter a deferral request, the program can also calculate deferral interest. For more information, see Calculating Deferral Interest .
Deferral of FI documents from a previous fiscal year
If you want to defer documents posted in previous fiscal years that were carried forward to the new fiscal year with year-end closing operations, your selection of documents is not allowed to include any posted in the current fiscal year. If you post a deferral with “carried forward documents”, the program flags the reverse postings and posted deferral request with this as well.
If the master data of the FM account assignment is no longer up-to-date in the deferral fiscal year, the program determines the current account assignment and copies it to the deferral request as a default value. The program also writes this account assignment in the FI document for the reverse posting.
When you are posting the deferral request, the program generates reverse postings for the source documents for the deferral amounts. To do so, the program generates a new FI document for the original FI document. The due date of the reverse posting corresponds to the posting date of the deferral request.
For an overview of the postings generated by the system when deferring a request, choose Example: Posting a Deferral Request .
You reverse a deferral when the debtor does not pay the receivable, not even by the new due date.This is also known as cancellation of a deferral request.
If errors occur when a deferral is posted, a list is displayed containing all the documents already posted. You must reverse these documents, otherwise data may be inconsistent. Once you have reversed these documents, you must post the deferral again.
You also reverse postings if you have to change the due date of a posted deferral request.
For more information on this, see Reversing Deferral Requests .
You should delete any deferral requests you no longer need to process. For more information, see Deleting a Deferral Request .
Once the deferral request has been posted, you can use the archiving function of the Financial Accounting component to archive the original FI document, since it is not necessary to retain a link between the deferred FI document and the deferral document.
