• What is the cause and solution for SAP error message WG043 - Incorrect MRP controller & sent / determined ?

  SAP Error Message:
  
  WG043 - Incorrect MRP controller & sent / determined
  
  Cause:
  This error occurs during the Material Requirements Planning (MRP) run or related transactions when there is a mismatch or inconsistency between the MRP controller assigned to a material and the MRP controller that is either sent or determined by the system. Essentially, the system detects that the MRP controller in the material master or the planning file entry does not match the expected or configured MRP controller for the planning run or process.
  Common causes include:  
  
  The MRP controller assigned to the material master (in MRP 1 view) is different from the MRP controller used in the planning run or the one stored in the planning file.  
  Changes in MRP controller assignments that were not properly updated or synchronized.  
  Incorrect or inconsistent configuration in the MRP controller settings or planning parameters.  
  Data inconsistencies due to manual changes or incomplete master data maintenance.
  
  
  Solution:
  To resolve the WG043 error, follow these steps:
  
  
  Check the MRP Controller in the Material Master:
  
  Go to transaction MM02 (Change Material) or MM03 (Display Material).
  Navigate to the MRP 1 view.
  Verify the MRP controller assigned to the material.
  
  
  
  Check the MRP Controller in the Planning File Entry:
  
  Use transaction MD21 (Display Planning File Entry) or MD22 (Change Planning File Entry).
  Verify the MRP controller assigned to the material in the planning file.
  
  
  
  Synchronize or Correct the MRP Controller:
  
  If there is a mismatch, update the MRP controller in the material master to the correct value.
  Alternatively, if the planning file entry is incorrect, delete and regenerate the planning file entry using MD20 (Create Planning File Entry) or by running MRP again.
  
  
  
  Check MRP Controller Configuration:
  
  Verify the MRP controller settings in customizing (SPRO) under Production ? Material Requirements Planning ? Master Data ? Define MRP Controllers.
  Ensure that the MRP controller is correctly defined and active.
  
  
  
  Re-run MRP:
  
  After correcting the MRP controller, run MRP again (transaction MD01, MD02, or MD03) to ensure the error is resolved.
  
  
  
  Additional Checks:
  
  If the error persists, check for user exits or custom enhancements that might affect MRP controller determination.
  Review change logs or transport requests if recent changes were made to MRP controllers or material master data.
