The accrual/deferral functionality is a function that allows you to accrue or defer interest or other cash flows for financial transactions. The procedures that are supported when configuring the accrual/deferral functionality are difference and amortization. Difference is a procedure that calculates the difference between the planned and posted cash flows and posts it as an accrual or deferral. Amortization is a procedure that calculates the amortized cost of a financial transaction and posts the difference between the nominal value and the amortized cost as an accrual or deferral.
