  SAP Error Message: WE045
  Text: "Material number & already assigned as set EAN"
  
  
  Cause:
  This error occurs during the processing of IDoc messages (typically inbound IDocs related to material master data, e.g., message type MATMAS) when the system tries to assign an EAN (European Article Number, i.e., barcode) to a material, but the EAN is already assigned to another material or set in the system.
  In other words, the EAN (barcode) you are trying to assign to a material is already linked to another material or material set in SAP. Since EANs must be unique identifiers for materials, SAP prevents duplicate assignments to maintain data integrity.
  
  When does it occur?
  
  During inbound IDoc processing for material master data (e.g., MATMAS IDocs).
  When updating or creating material master records with EANs.
  When trying to assign an EAN that is already assigned
