  SAP Error Message: WG091
  Text: For PO copy for material &, send suppliers. Wrong: &/&
  
  Meaning / Cause:
  This error typically occurs during the process of copying or creating a Purchase Order (PO) when the system tries to send the PO to the supplier(s). The message indicates that there is an issue with the supplier data related to the material in the PO.
  More specifically:
  
  The system is trying to send the PO to a supplier for a particular material.
  However, the supplier information (such as the vendor number or partner function) is incorrect, missing, or inconsistent.
  The placeholders & and &/& in the message represent the material number and supplier/vendor details, respectively.
  This can happen if the supplier is not assigned correctly to the material master or if the partner function for the supplier in the PO is not maintained properly.
  
  
  Common Causes:
  
  
  Missing or Incorrect Vendor Assignment in Material Master:
  
  The material master record does not have a valid vendor assigned in the purchasing view.
  
  
  
  Partner Function Not Maintained:
  
  The partner function for the supplier in the PO header or item is missing or incorrect.
  
  
  
  Vendor Master Data Issues:
  
  The vendor master record might be blocked or incomplete.
  
  
  
  Copy Control Settings:
  
  Incorrect copy control settings between documents (e.g., from PR to PO) might cause supplier data not to be copied correctly.
  
  
  
  Output Determination Issues:
  
  The output type or message determination for sending the PO to the supplier is not configured properly.
  
  
  
  
  Solution / How to Fix:
  
  
  Check Material Master:
  
  Go to transaction MM03 (Display Material).
  Check the Purchasing view to ensure that a valid vendor is assigned to the material.
  If missing, assign a valid vendor in the Purchasing view (transaction MM02).
  
  
  
  Check Vendor Master:
  
  Use transaction XK03 or MK03 to display vendor master data.
  Verify that the vendor is active and not blocked for purchasing.
  
  
  
  Check Partner Functions in PO:
  
  In the PO, check the partner tab to ensure the supplier is correctly assigned with the appropriate partner function (e.g., VN for vendor).
  If missing, add the correct partner.
  
  
  
  Review Copy Control Settings:
  
  Use transaction OMJJ or NACE to check copy control settings between documents.
  Ensure that supplier data is correctly copied from the source document to the PO.
  
  
  
  Check Output Determination:
  
  Use transaction NACE to check output types for purchasing documents.
  Verify that the output message for sending PO to the supplier is correctly configured and assigned.
  
  
  
  Recreate or Correct the PO:
  
  After correcting the master data or partner functions, try to recreate or copy the PO again.
