  SAP Error Message: WRF_APC657
  Text:
  
  You cannot copy prepack/variant information to a non-generic material.
  
  Cause:
  This error occurs when you attempt to copy prepack or variant configuration data from a generic material to a material that is not defined as generic in the system. In SAP, generic materials are special materials used in variant configuration scenarios to represent a family of products with different variants. Prepack or variant information is only valid for generic materials because it relates to variant configuration.
  If the target material is not flagged as generic (i.e., it does not have the variant configuration indicator set), the system prevents copying variant-specific data such as prepack or variant information to it.
  
  Explanation:
  
  Generic Material: A material that is set up for variant configuration (e.g., configurable products). It has the "Generic" indicator set in the material master.
  Prepack/Variant Information: Data related to variant configuration, such as variant characteristics, prepack definitions, or variant-specific BOMs.
  Non-generic Material: A standard material without variant configuration capabilities.
  
  The system enforces this restriction to maintain data consistency and integrity in variant configuration processes.
  
  Solution:
  
  
  Check Material Master Settings:
  
  Verify if the target material is flagged as a generic material.
  Go to transaction MM02 (Change Material) ? Basic Data 1 tab or Sales: General/Plant tab (depending on SAP version) and check if the "Generic" indicator (or variant configuration indicator) is set.
  
  
  
  Set the Material as Generic (if appropriate):
  
  If the target material should be a generic material (i.e., it is intended to be configurable), set the generic indicator.
  Save the changes and then retry copying the prepack/variant information.
  
  
  
  If the Material Should Not Be Generic:
  
  Do not copy prepack/variant information to it.
  Instead, create or use a generic material for variant configuration purposes.
  
  
  
  Review Variant Configuration Setup:
  
  Ensure that variant configuration is properly set up for the materials involved.
  Check the configuration profile and material type settings.
