  Error Message
  VP220: Partner function & must be unique
  
  Cause
  This error occurs when you try to assign the same partner function more than once to a business partner or in a sales document where the partner function is expected 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 document or master data record.
  For example:
  
  In a sales order, you cannot assign two different partners with the same partner function.
  In customer master or business partner master data, the partner function must be unique per partner.
  
  
  When does it occur?
  
  During sales document creation or change (e.g., sales order, quotation).
  During business partner or customer master data maintenance.
  When copying or creating documents where partner functions are assigned.
