• What is the cause and solution for SAP error message WES_OUTBOUND131 - Material &1 / &2 of mat.grp.hierar. level &3 ignored, as no EAN is stored ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  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 the relevant field (usually in the material master, in the EAN/UPC tab).
  The material group hierarchy level expects an EAN for outbound processing, but none is assigned.
  Possibly, the integration or outbound interface requires EAN for identification, and without it, the material cannot be processed.
  
  
  Solution:
  
  
  Check and maintain the EAN for the material:
  
  Go to transaction MM02 (Change Material Master).
  Enter the material number (&1) and plant (&2).
  Navigate to the Additional Data tab or EAN/UPC tab.
  Maintain the correct EAN/UPC code for the material.
  Save the changes.
  
  
  
  Verify material group hierarchy settings:
  
  Check if the material group hierarchy level (&3) requires EANs.
  If EANs are mandatory for outbound processing, ensure all materials in that group have EANs.
  
  
  
  Reprocess the outbound message or transaction:
  
  After maintaining the EAN, retry the outbound processing or message generation.
  
  
  
  If EAN is not applicable:
  
  Review the business process to confirm if EAN is mandatory.
  If not, adjust the configuration or logic to allow processing without EANs, if possible.
