  Error Message
  WE230 - Additional EANs already used for reference material
  
  Cause
  This error occurs during the processing of IDocs (typically related to material master data, e.g., message type MATMAS) when the system tries to assign an Additional EAN (European Article Number) to a material, but the EAN is already assigned to another material in the system.
  In SAP, EANs (barcodes) must be unique identifiers for materials. If an EAN is already linked to one material, it cannot be assigned to another material as an additional EAN. The system checks for uniqueness and throws this error if a duplicate is detected.
  
  When does it occur?
  
  During inbound IDoc processing for material master data (e.g., MATMAS).
  When updating or creating material master records with additional EANs.
  When the EAN being assigned is already linked to a different material in the system.
