  Error Message
  WXPB129: Specify a material group
  
  Cause
  This error occurs when a material group is required but has not been specified in a transaction or master data maintenance. Material groups are used in SAP to classify materials for reporting, pricing, and organizational purposes. The system expects a material group to be entered, but the field is left blank or the input is invalid.
  Common scenarios where this error might appear:
  
  Creating or changing a material master record (MM01/MM02) without specifying the material group.
  During sales order processing or pricing where material group is mandatory.
  In custom programs or user exits where material group is checked as a required field.
  
  
  Solution
  
  Specify a valid material group in the required field. Material groups are usually defined in the system and can be selected from a dropdown or search help.
  If you do not know the correct material group, consult your master data team or check the existing material master records for similar materials.
  If the material group field is missing or not mandatory but the system expects it, check the configuration or user exit that enforces this requirement.
  In case of custom developments or enhancements, verify if there is a validation logic that requires the material group and adjust accordingly.
  
  
  How to Specify Material Group
  
  Go to the material master transaction (e.g., MM01 or MM02).
  Navigate to the Basic Data 1 view.
  Locate the Material Group field.
  Enter the appropriate material group code or use the search help (F4) to select one.
  Save the material master record.
  
  
  Additional Information
  
  Material Group (MATKL) is a key classification field in SAP MM.
  Material groups help in grouping materials for pricing, reporting, and inventory management.
  Material groups are maintained in SPRO under:
  Logistics - General > Material Master > Settings for Key Fields > Define Material Groups
  If the material group is not defined or missing, you may need to create it in the customizing.
  Sometimes, the error can be triggered by user exits or BAdIs that enforce additional validations.
