  1. Cause of the Message
  
  This warning message appears when consumption values (historical consumption data used for forecasting and planning) that are assigned to specific MRP areas have been deleted.
  MRP areas are organizational units within a plant that allow for more granular material requirements planning.
  The deletion can occur due to:
  
  Manual deletion of consumption data.
  Data cleanup or archiving activities.
  Changes in MRP area assignments or configurations.
  System processes or transactions that remove obsolete or inconsistent consumption data.
  
  
  
  
  2. Meaning and Impact
  
  The message is a warning (W), not an error, indicating that consumption values linked to MRP areas have been removed.
  This can affect:
  
  Forecasting accuracy.
  Planning results for the affected MRP areas.
  
  
  It serves as an alert to planners or system administrators that historical data used for planning is no longer available for certain MRP areas.
  
  
  3. Solution / Recommended Actions
  
  Verify the Deletion:
  
  Check if the deletion was intentional (e.g., part of data cleanup).

  Review MRP Area Configuration:
  
  Ensure MRP areas are correctly defined and assigned.
