Accruals 
You can accrue committed amounts in funds management to post expenses in the fiscal periods in which they occur.
Note
Since off-invoice discount committed amounts expense in SAP ERP as they occur, no accrual postings are necessary. Off-invoice discounts are imported from SAP ERP into SAP CRM and posted as expenses, payments, and fund consumptions. Accruals are calculated for all other committed amounts.
Product category data can be exchanged between SAP CRM and SAP ERP. For more information, see SAP Note 1106673.

Calculate accruals
You can schedule an accrual calculation run in the batch processing framework. The accrual method can use various reference data types, depending on what you have defined in Customizing. Examples include sales volumes (SAP ERP), trade promotion management (TPM) planning data, or funds data. The accrual results are stored within the accrual staging area.
Edit accrual results
You can edit the accrual results before posting accruals by performing a search and choosing Edit Amount in the Result List.
Post accruals
You must schedule an accrual posting run in the batch processing framework to post the accrual results as fund postings, which are transferred to SAP ERP financials.
Reverse accruals
To reverse an accrual posting run, you can schedule an accrual reversal run in the batch processing framework. Accrual reversals represent an entire accrual posting run and not a single fund posting.
