  SAP Error Message:
  WES_OUTBOUND121 No EAN could be defined for material &1 and unit of measure &2
  
  Meaning / 
  Cause:
  This error occurs when the system tries to determine an EAN (European Article Number, also known as GTIN - Global Trade Item Number) for a specific material and unit of measure but fails to find a valid EAN assigned in the system.
  
  The EAN is typically required for outbound processes such as shipping, labeling, or EDI (Electronic Data Interchange) messages.
  The system looks for an EAN that matches both the material number and the unit of measure (UoM).
  If no EAN is maintained for the combination of material and UoM, the system cannot proceed and throws this error.
  
  
  Common Scenarios:
  
  Outbound delivery processing where EAN is mandatory.
  EDI or IDoc processing where EAN is required for material identification.
  Label printing or barcode generation where EAN is needed.
  Integration with warehouse management or
