• What is the cause and solution for SAP error message M3349 - EAN/packaging data copied from reference although base unit changed ?

  The SAP error message M3349 indicates that there is an issue with the handling of EAN (European Article Number) or packaging data when the base unit of measure for a material has been changed. This error typically arises in the context of material master data management, particularly when dealing with packaging and EAN information.
  Cause:
  The error occurs when the system detects that the EAN or packaging data has been copied from a reference material, but the base unit of measure for the material has been changed.

  To resolve this error, you can take the following steps:
  
  
  Check Base Unit of Measure: Verify the base unit of measure for the material in question. Ensure that it is set correctly according to your business requirements.
  
  
  Review EAN/Packaging Data: Check the EAN and packaging data associated with the material. If the base unit of measure has changed, you may need to update or remove the EAN and packaging data to ensure it aligns with the new base unit.
