  The SAP error message MF004 typically indicates that the system is unable to find a valid product group for the material you are trying to process. This error can occur in various contexts, such as during material master creation, planning, or when executing certain transactions related to materials.
  Cause:
  
  Missing Product Group: The most common cause is that the material you are working with does not have a product group assigned to it in the material master data.
  Incorrect Configuration: The product group may not be properly configured in the system, or it may not exist in the relevant organizational unit.
  Data Inconsistency: There may be inconsistencies in the data, such as missing or incorrect entries in the material master or related tables.
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to the material master record (transaction code MM03).

  Check Configuration:
  
  Review the configuration settings for product groups in the system. This may involve checking the relevant customizing settings in SPRO (transaction code SPRO).

  Data Consistency Check:
