  Error Message
  WRF_APC062: Material type for material &1 is blank
  
  &1 will be replaced by the material number in the actual message.
  
  
  Cause
  This error occurs because the system is trying to process a material, but the Material Type field for that material is empty or not maintained in the material master record.
  
  The Material Type is a mandatory field in the material master (usually in the Basic Data 1 view).
  If this field is blank, SAP cannot determine how to handle the material in various processes, including planning, procurement, or production.
  This error often appears in processes related to APC (Advanced Planning and Optimization) or other planning scenarios where material type is essential for logic branching.
  
  
  Solution
  
  
  Check the Material Master:
  
  Go to transaction MM03 (Display Material).
  Enter the material number mentioned in the error message.
  Navigate to the Basic Data 1 view.
  Verify if the Material Type field is filled.
  
  
  
  Maintain the Material Type:
  
  If the material type is blank, use transaction MM02 (Change Material).
  Enter the material number.
  Go to Basic Data 1 view.
  Enter the appropriate material type (e.g., ROH, FERT, HALB, etc.).
  Save the changes.
  
  
  
  Check Material Creation Process:
  
  Ensure that when materials are created, the material type is always maintained.
  If materials are created via interfaces or batch jobs, check those processes for missing data.
  
  
  
  Re-run the Process:
  
  After maintaining the material type, re-run the process that triggered the error.
