If the business partner is temporarily unable to pay his open items, the due date is postponed. Until the date specified, the deferred item will not be dunned in a dunning run and will not be selected by the payment run. Once the deferral date has passed, the item can be dunned again and collected.
Deferral can be performed manually in the document change transaction or automatically during returns processing. You can enter a deferral date when you post the document or when you change the line items in the document. The deferral does not change the original due date. The deferral date is used instead of the due date to automatically create dunning notices or debit memos.

Deferral can be posted as an installment plan with only one installment. The advantage of this method is that you can calculate and post charges and interest.
