    Error Message Text:
    WER121 - "No valid partner found for partner function &"
    
    
    Cause: This error occurs when the system cannot find a valid business partner assigned to a specific partner function in a document or master data. In SAP, partner functions define roles of business partners (e.g., sold-to party, ship-to party, payer, contact person). If the partner function is required but no partner is assigned or the assigned partner is invalid or incomplete, the system raises this error. Common scenarios include: Missing partner assignment in sales documents (e.g., sales order, billing document). Partner function not maintained in customer master or vendor master. Incorrect or incomplete partner determination procedure. Partner determination procedure not assigned or configured properly.
    Solution: Check Partner Assignment: Verify that the required partner function is assigned a valid partner in the document or master data. For sales documents, check the partner tab and assign the correct partner. Maintain Partner Determination Procedure: Go to transaction VOPA (Partner Determination Procedures)
