  Error Message
  WY072: Partner function & must be unique in master record
  
  Cause
  This error occurs when you try to assign the same partner function more than once to a single business partner master record or customer/vendor master record where the partner function is supposed to be unique.
  In SAP, certain partner functions (like Sold-to party, Ship-to party, Bill-to party, Payer, etc.) must be assigned only once per master record. If you attempt to assign the same partner function multiple times, the system throws this error.
  
  When does it occur?
  
  While creating or changing a customer or vendor master record.
  While maintaining business partner roles and partner functions.
  During sales document processing if partner functions are maintained incorrectly.
  When customizing partner functions in the IMG and assigning them to roles.
  
  
  Solution
  
  
  Check the master record:
  
  Go to the customer/vendor or business partner master data.
  Review the partner functions assigned.
  Ensure that the partner function in question is assigned only once.
  
  
  
  Remove duplicate partner functions:
  
  If duplicates exist, delete the extra entries so that each partner function appears only once.
  
  
  
  Adjust partner function assignment in customizing (if applicable):
  
  Go to SPRO ? Logistics General ? Business Partner ? Partner Functions.
  Verify the partner function settings and uniqueness constraints.
  If you have custom partner functions, ensure they are configured correctly.
  
  
  
  Check sales document partner assignment:
  
  If the error occurs during sales order creation, check the partner tab.
  Remove duplicate partner functions.
  
  
  
  Use transaction codes:
  
  For Business Partner: BP
  For Customer Master: XD02 (Change), VD02 (Change Sales Area Data)
  For Vendor Master: XK02
  
  
  
  
  Additional Information
  
  Partner functions define the role of a partner in a business transaction (e.g., Sold-to party, Ship-to party).
  Some partner functions are mandatory and unique per master record.
  The error ensures data consistency and prevents ambiguity in partner roles.
  If you need multiple partners with the same role, consider if the business process or master data model needs adjustment.
