SAP Message WU254 - The promotion contains materials that have not been assigned to a module

Diagnosis
Subsequent processing has already been carried out using manual modulesfor the promotion. At the time of the first subsequent processing step,all materials were assigned to at least one module. 'Listing withmanual modules' was therefore defined for the promotion.
However, the promotion contains materials which are not yet assigned toa module. This means that materials were added to the promotion at alater date. Subsequent processing for the material is only possiblewhen the material has been assigned to a module.

System Response
To ensure that data remains consistent, processing is not carried out.

Procedure
Assign the new material(s) to an existing promotion module. If theexisting modules have already been listed, create a new module, andassign the material(s) to this. Restart terminated subsequentprocessing. Do not forget to subsequently list the new module youcreated.
