• What is the cause and solution for SAP error message M3652 - Lot size of production version does not match alternative BOM ?

  The SAP error message M3652, "Lot size of production version does not match alternative BOM," typically occurs in the context of production planning and material management when there is a mismatch between the lot size defined in the production version and the lot size specified in the alternative Bill of Materials (BOM).
  Cause:
  
  Mismatch in Lot Sizes: The lot size defined in the production version does not match the lot size defined in the alternative BOM. This can happen if the production version is set up with a specific lot size that is different from what is defined in the BOM.
  Incorrect Configuration: The production version or the alternative BOM may not be configured correctly, leading to discrepancies.
  Changes in BOM or Production Version: If there have been recent changes to either the BOM or the production version, it may lead to inconsistencies that trigger this error.
  
  Solution:
  
  
  Check Lot Sizes: Verify the lot sizes defined in both the production version and the alternative BOM. Ensure that they match. You can do this by:
  
  Navigating to the production version in the SAP system and checking the lot size.
  Checking the alternative BOM for the same material and confirming its lot size.

  Changing the lot size in the production version to match the alternative BOM.
  Modifying the alternative BOM to match the lot size in the production version.
  
  
  
  Review Configuration: Ensure that the configuration for both the production version and the BOM is correct. This includes checking for any settings that may affect lot size determination.
  
  
  Recreate Production Version: If the issue persists, consider recreating the production version to ensure that it is correctly linked to the appropriate BOM.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on managing production versions and BOMs.
