Trade Promotion Execution 
In this process, you execute trade promotions. After you have planned a trade promotion (see Trade Promotion Planning), you negotiate the actual execution with your customers and the trade spends related to it. As soon as you receive orders within trade promotions, the system transfers the planning data to SAP R/3. Since the system recognizes the relationship between the order and the trade promotion, trade spends are taken into account during invoicing or accruals are built up for rebate agreements. As soon as the vendor pays out rebates (for example, because of sales figures), the system reverses the accruals.

You can also carry out a simulation of billing.

1. The system transfers rebate agreements and condition records (SAP R/3)
2. The order determines the trade promotion and conditions (SAP CRM)
The system can carry out a validation, that is, check whether or not a trade promotion is relevant for the respective order item. To do this, the system can use data that is not part of the trade promotion data and could therefore not be checked at the time of campaign determination.

You can only use the validation by implementing the Business Add-Ins (BAdIs) CRM_CAMPAIGN_BADI and CRM_MKTPL_VALI.
