  Certainly! Here's a detailed explanation regarding the SAP error message WE064: New EAN replaces previous EAN, also as empty containers EAN:
  
  Error Message: WE064
  Text:
  
  New EAN replaces previous EAN, also as empty containers EAN
  
  Cause:
  This message occurs during the processing of IDoc messages related to material master data or packaging data, specifically when handling EAN (European Article Number) or GTIN (Global Trade Item Number) assignments.
  
  The system detects that a new EAN being assigned to a material or packaging type replaces an existing EAN.
  The replaced EAN is also used as an empty container EAN (i.e., an EAN assigned to an empty packaging material or container).
  This situation can cause inconsistencies or conflicts in the material master or packaging data because the same EAN is being reassigned or overwritten.
  
  In other words, the system warns that the new EAN you are trying to assign is replacing an EAN that is currently used as an empty container EAN, which might not be intended or could lead to data integrity issues.
  
  When does it occur?
  
  During IDoc inbound processing (e.g., MATMAS, PACKMAT, or similar IDocs) when updating or creating material master or packaging data.
  When EAN/GTIN data is maintained or changed via transactions or interfaces.
  When the same EAN is assigned to different packaging levels or material types, especially if one is an empty container.
  
  
  Solution:
  
  
  Check the EAN assignments:
  
  Verify the current EAN assignments in the material master (transaction MM03) or packaging material master (transaction PACK or MM02).
  Identify which material or packaging uses the EAN as an empty container.
  
  
  
  Analyze the business requirement:
  
  Confirm if the new EAN should indeed replace the old one.
  Check if the old EAN is still valid or if it should be deleted or deactivated.
  
  
  
  Correct the EAN data:
  
  If the EAN should not replace the old one, adjust the incoming data or IDoc to avoid overwriting.
  If the replacement is correct, ensure that the old EAN is properly removed or flagged as inactive in the system.
  Maintain the EAN assignments carefully to avoid conflicts between material and packaging EANs.
  
  
  
  Check customizing and master data consistency:
  
  Review the configuration for EAN/GTIN handling in SAP.
  Ensure that the packaging material and empty container EANs are correctly maintained and do not overlap with product EANs.
  
  
  
  Reprocess the IDoc or data after correction:
  
  Once the data is corrected, reprocess the IDoc or update the material master data.
