Condition contracts are used in this process to enter sales commission agreements with external sales agents. In a condition contract you specify the commission recipient, the organizational and process control parameter, the business volume selection criteria, the sales commission conditions, and the settlement calendar with the settlement dates for delta accrual, partial settlement, and final settlement. The delta accruals settlement reflects a procedure in which accruals for commissions are not posted together with transactional documents but are posted at a later date in a specific settlement run. When carrying out the partial and final settlements of a condition contract, you perform the sales commission calculation based on business volume and commission conditions and you create the settlement documents that reflect an invoice from the external sales agents for the arrangement of sales deals. This scope item supports two data sources for the business volume determination: sales and distribution (SD) billing documents that have already been paid and SD billing documents without check for payment.
