  SAP Error Message:
  WES_OUTBOUND131
  Text: Material &1 / &2 of mat.grp.hierar. level &3 ignored, as no EAN is stored
  
  Meaning / 
  Cause:
  This message occurs during outbound processing (often in SAP WM/EWM or related logistics modules) when the system tries to process or send data related to a material that belongs to a material group hierarchy level, but the material does not have an EAN (European Article Number, i.e., barcode) assigned or stored in the system.
  
  Material &1 = Material number
  &2 = Plant or other identifier
  &3 = Material group hierarchy level
  
  The system expects an EAN to be present for the material at the specified material group hierarchy level to proceed with outbound processing (e.g., for labeling, identification, or integration with external systems). Since no EAN is found, the material is ignored/skipped.
  
  
  Cause:
  
  The material master data is incomplete or missing the EAN/UPC barcode.
  The EAN is not maintained in
