  Check MRP Configuration:
  
  Go to the MRP configuration settings in your SAP system. This can usually be found in the SPRO transaction under the MRP settings.

  Identify Duplicates:
  
  Look for any duplicate entries in the MRP configuration. This may involve checking the settings for specific materials or product groups that may have been incorrectly configured.
  
  
  
  Correct Configuration:
  
  If you find multiple MRP modules assigned to the same level, you will need to decide which module should remain and remove the others. This may involve consulting with your planning team to understand the implications of the changes.
  
  
  
  Test Changes:
  
  After making the necessary corrections, run a test MRP run to ensure that the error does not reoccur and that the MRP process functions as expected.
  
  
  
  Documentation:
  
  Document the changes made to the configuration for future reference and to help prevent similar issues from arising.
