• What is the cause and solution for SAP error message WES_OUTBOUND133 - Material &1 / &2 ignored, as no EAN is stored ?

  SAP Error Message:
  
  WES_OUTBOUND133 Material &1 / &2 ignored, as no EAN is stored
  
  Meaning / Cause:
  This error occurs during outbound processing (e.g., delivery or shipping processes) when the system tries to handle a material but cannot find an associated EAN (European Article Number, also known as GTIN - Global Trade Item Number) for that material in the relevant plant or sales organization context.
  
  Material &1 = Material number  
  &2 = Plant or relevant organizational unit
  
  The EAN is required for identification and communication with external systems (e.g., warehouse, logistics partners, or EDI interfaces). If the EAN is missing, the system cannot process the material for outbound delivery or related processes, so it ignores the material and issues this warning/error.
  
  Typical Causes:
  
  EAN not maintained for the material: The material master does not have an EAN assigned in the relevant plant or sales org.
  EAN maintained but not valid for the current organizational context: EAN might be maintained but not for the plant or sales org involved in the outbound process.
  Incorrect or incomplete master data setup: The material master or EAN master data is incomplete or inconsistent.
  Customizing or interface expects EAN: Some outbound processes or interfaces require EANs for materials, and if missing, the system flags this.
  
  
  How to Check / Verify:
  
  
  Check EAN in Material Master:
  
  Transaction: MM03 (Display Material)
  Navigate to Additional Data ? EAN/UPC tab
  Verify if an EAN is maintained for the material.
  
  
  
  Check EAN per Plant:
  
  EANs can be plant-specific. Make sure the EAN is maintained for the plant (&2) mentioned in the error.
  
  
  
  Check if EAN is valid for the sales org or distribution channel if relevant.
  
  
  Check if the EAN is active and not flagged for deletion.
  
  
  
  Solution / Resolution:
  
  
  Maintain EAN for the material:
  
  Use transaction MM02 (Change Material)
  Go to Additional Data ? EAN/UPC tab
  Add the correct EAN for the material and plant.
  
  
  
  If multiple EANs exist, ensure the correct one is assigned and active.
  
  
  If EAN is not required for your business process, check if the outbound process or interface can be adjusted to not require EANs.
  
  
  If the error occurs in an interface (e.g., EDI or warehouse integration), coordinate with the technical team to handle missing EANs or adjust mapping.
  
  
  
  Additional Information:
  
  EAN/GTIN is a standard barcode number used globally to identify trade items.
  In SAP, EANs are stored in the material master under the Additional Data tab.
  Some industries (e.g., retail, pharmaceuticals) require EANs for all materials.
  Missing EANs can cause issues in automated picking, packing, shipping, and EDI communication.
  This message is often a warning but can block processing depending on configuration.
