System Response
The system cannot calculate any sales prices in the distribution chainfor the plants selected.

Procedure
If you enter a plant on the initial screen for sales pricecalculations, you no not have to enter a distribution chain. If you donot enter a distribution chain, the system takes all distributionchains into account to which the plant is assigned and for whichplant-specific sales prices are defined. Try the transaction again,entering the plants but leaving the distribution chain empty.
If the distribution chains determined are not what you expected, checkthe distribution chains assigned to the plants in the plant masterdata. Then check which pricing levels are allowed below thedistribution chain level. You check this in(Distribution chain control).
