You can enter an accrual rate manually in each condition record. The accrual rate should reflect, as accurately as possible, the rate at which the rebate will be calculated at final settlement.

Every time you process a rebate-relevant billing document (an invoice, a credit or debit memo), the system automatically posts an accrual to financial accounting (FI). Within FI, the rebate accrual is posted to two accounts: a sales deduction account and an accrual account. The accrual account is cleared when the rebate agreement is settled with a credit memo.
