SAP Note 26958 - Rounding error for rebate with FC

Symptom:

The rebate payment causes large rounding differences.

If the currency of the condition record deviates from the payment currency or local currency, a currency translation occurs too soon.

Example:
The volume rebate condition is 0.25 DEM per 1 Kg
The local currency is NLG. The exchange rate is: 1 DEM is 1.13 NLG.
the sales volume qualifying for volume-based rebate is 100 Kg.

The payment we calculated is: 0.25 DEM is 0.28 NLG.
0.28 NLG times 100 Kg gives 28.00 NLG.
The payment should be calculated as:
0.25 DEM times 100 Kg gives 25.00 DEM.
25.00 DEM is 28.25 NLG.

Drill-down can also cause large rounding differences.
