  The SAP error message WM257 ("Value-only mat. for mat. group & not defined (edit mat. group)") typically occurs in the Warehouse Management (WM) module when you are trying to perform an operation involving a material that is classified as a "value-only" material, but the system cannot find the necessary configuration for the material group associated with that material.
  Cause:
  
  Material Group Configuration: The material group for the material in question is not properly defined in the system. This can happen if the material group is set up as a value-only material group but lacks the necessary settings or definitions.
  Material Master Data: The material master data for the specific material may not be complete or correctly configured, particularly in the context of warehouse management.
  Warehouse Management Settings: There may be issues with the warehouse management settings that relate to how value-only materials are handled.
  
  Solution:
  
  
  Check Material Group Configuration:
  
  Go to the transaction code OMD1 (or use the appropriate path in your SAP system) to check the configuration of the material group.
