SAP Note 13829 - Canc. billing docs influence sales qual. for rebate

Symptom:

Cancelled billing documents are considered in the sales qualifying for rebate. They increase the sales qualifying for rebate and are displayed in the drill-down.

Cause and prerequisites

The cancellation billing document type (for example, S1) is marked as not qualifying for volume-based rebate. As a result, the cancellation billing document does not reduce the sales qualifying for rebate.
The cancellation billing document contains the same values as the cancelled billing document. Only the values of the cancellation
billing docuement have a different +/- sign. For this reason, the total of cancellation billing document and the cancelled billing document is 0. If the cancellation billing document and the cancelled billing document are qualifying for volume-based rebate, the cancellation is correctly taken into account during the rebate settlement.

Solution
1) Mark the cancellation billing document as qualifying for volume-based rebate.

Caution: If the cancellation billing document is marked as qualifying for volume-based rebate, you may only cancel billing documents qualifying for volume-based rebate with this cancellation billing document type. If you cancel a billing document not qualifying for volume-based rebate with a cancellation billing document qualifying for volume-based rebate, this would reduce the sales qualifying for rebate although the original billing document is not qualifying for volume-based rebate.
