• What is the cause and solution for SAP error message WY013 - Partner function & already maintained ?

  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.
  
  
  
  Avoid Duplicate Entries:
  
  Do not enter the same partner function twice.
  If you need to assign multiple partners, use different partner functions.
  
  
  
  Correct Partner Function Assignment:
  
  If you mistakenly tried to assign the same partner function twice, remove the duplicate entry.
  If you need to assign multiple partners, consider if a different partner function is appropriate or if the business process needs adjustment.
  
  
  
  Check Customizing (if applicable):
  
  In some cases, partner functions are defined in customizing (SPRO) under Sales and Distribution ? Partner Determination.
  Ensure that the partner determination procedure does not allow duplicates if that is not desired.
  
  
  
  
  Related Information:
  
  Partner Functions: Roles assigned to business partners in SAP SD and other modules.
  Partner Determination Procedure: Configuration that controls which partner functions are required or optional in a transaction.
  Common Transactions:
  
  VA01/VA02/VA03 – Sales Order processing
  VL01N/VL02N/VL03N – Delivery processing
  VF01/VF02/VF03 – Billing document processing
  XD01/XD02/XD03 – Customer master data
  
  
  
  
  Summary:
  
  Error WY013 means you are trying to maintain a partner function that already exists.
  Fix: Remove the duplicate partner function entry or assign a different partner function.
  Check: Partner assignments in the document or master data and partner determination customizing.
