Hello,
Accrual Rate defined in the rebate agreement is used to post the accruals in accounting.
When you create the Rebate agreement, you are defining the accrual rate on based on which system should make this accrual Posting.
For the invoice that are created in the system ( if the document is relevant for the rebate agreement i.e Account, Product etc) then the in pricing tab of the document, you would also find the additional price components : Accrual Rate (%) and Rebate Settlement Due Rate (%).
As well as in the journal entry for the invoice, you will find additional GL ( Depending on your configurations) that corresponds to the Accrued value.
Accrual Posting for Rebates
When you release a rebate-relevant billing document for transfer to accounting, an extract is created in the rebate application, and pricing checks whether a valid rebate agreement exists for this business transaction. If a valid agreement is found, it accumulates sales volume and posts accruals in accounting so that the funds are available later during the settlement.
