• What is the cause and solution for SAP error message /PLMI/BO_MAT028 - EAN &1 is already used in material &2; enter a different EAN value ?

  The SAP error message /PLMI/BO_MAT028 EAN &1 is already used in material &2; enter a different EAN value indicates that you are trying to assign an EAN (European Article Number) to a material that is already associated with another material in the system. This typically occurs when you are attempting to create or update a material master record and the EAN you are trying to use is already in use by a different material.
  Cause:
  
  Duplicate EAN Assignment: The EAN you are trying to assign is already linked to another material in the SAP system.
  Data Entry Error: There may have been a mistake in entering the EAN, leading to an attempt to reuse an existing EAN.
  Material Master Configuration: The system is configured to prevent duplicate EANs for different materials to maintain data integrity.
  
  Solution:
  
  
  Check Existing EANs: 
  
  Use transaction code MM03 (Display Material) to check the material that is currently using the EAN you are trying to assign. 
  You can also use transaction MM02 (Change Material) to see the details of the material that is already using the EAN.
  
  
  
  Use a Different EAN: 
  
  If the EAN is indeed already in use, you will need to assign a different EAN to the material you are trying to create or update.
  
  
  
  Update Existing Material: 
  
  If the EAN should be associated with the new material, consider whether you need to update the existing material to remove the EAN or reassign it.
  
  
  
  Consult with Your Team: 
  
  If you are unsure about the EAN assignment, consult with your inventory management or product management team to determine the correct EAN to use.
  
  
  
  Check for System Configuration: 
  
  If you believe this is an error and the EAN should be allowed for multiple materials, you may need to check with your SAP Basis or configuration team to see if there are any settings that can be adjusted.
