• What is the cause and solution for SAP error message WE063 - New EAN replaces previous EAN, also as component EAN ?

  SAP Error Message:
  
  WE063 - New EAN replaces previous EAN, also as component EAN
  
  Cause of the Error
  This message occurs during the processing of IDoc messages related to material master or bill of materials (BOM) data, specifically when handling EAN (European Article Number) assignments.
  
  The system detects that a new EAN being assigned to a material or component replaces an existing EAN.
  The replaced EAN is also used as a component EAN in a BOM.
  This situation can cause inconsistencies because the EAN is linked both as a material identifier and as a component identifier in BOMs.
  The system issues this message as a warning or error to prevent unintended overwriting or conflicts in EAN assignments.
  
  
  Explanation
  
  EAN (European Article Number) is a barcode standard used to uniquely identify products.
  In SAP, EANs are maintained in material master records and can also be assigned to BOM components.
  When an IDoc tries to assign a new EAN that replaces an existing one, and that existing EAN is still referenced as a component EAN in BOMs, SAP raises this message.
  This is to ensure data integrity and avoid confusion in material/component identification.
  
  
  Solution / How to Resolve
  
  
  Check the EAN assignments:
  
  Verify the current EANs assigned to the material and BOM components.
  Use transaction MM03 (Display Material) to check EANs in the material master.
  Use transaction CS03 (Display BOM) to check component EANs.
  
  
  
  Analyze the IDoc data:
  
  Review the IDoc segment where the EAN is being changed.
  Confirm if the new EAN should indeed replace the old one.
  
  
  
  Adjust the EAN assignments:
  
  If the new EAN is correct, update the BOM components to reflect the new EAN.
  Alternatively, if the old EAN is still valid as a component EAN, reconsider replacing it.
  
  
  
  Synchronize EANs in BOM and material master:
  
  Ensure that EANs used in BOM components are consistent with material master EANs.
  If necessary, update BOM components to use the correct EANs.
  
  
  
  Reprocess the IDoc:
  
  After corrections, reprocess the IDoc to confirm the message no longer appears.
  
  
  
  Consult SAP Notes:
  
  Check for any SAP Notes related to message WE063 for specific patches or updates.
