WY013 - Details

• SAP Error Message:
  WY013 - Partner function & already maintained
  
  
  Cause:
  This error occurs when you try to assign or maintain a partner function in a business transaction (such as a sales order, delivery, billing document, etc.) that has already been assigned or maintained for the same partner function in that document or master data.
  In other words, the system is preventing duplicate entries of the same partner function for the same partner in the document or master record.
  
  Explanation:
  
  Partner functions define roles of business partners in a transaction (e.g., Sold-to party, Ship-to party, Payer, Bill-to party).
  Each partner function should be unique per document or master record.
  If you attempt to add the same partner function twice, SAP throws this error to avoid inconsistencies.
  
  
  
  Solution:
  
  
  Check Existing Partner Functions:
  
  Review the partner functions already assigned in the document or master data.
  Use transaction codes like VA03 (Display Sales Order), VD03 (Display Customer), or the relevant transaction to view partner assignments.
