  Error Message
  VP503: Partner & already exists for function &
  
  Cause
  This error occurs when you try to assign a business partner (e.g., a customer, vendor, contact person) to a partner function in a sales document or master data, but the same partner is already assigned to that partner function.
  In SAP Sales and Distribution (SD), each partner function (like Sold-to party, Ship-to party, Bill-to party, Payer, etc.) can only have one unique partner assigned. If you attempt to assign the same partner twice to the same partner function, the system throws this error.
  
  When does it typically occur?
  
  During sales order creation or change (transaction VA01/VA02).
  When maintaining customer master or partner determination.
  When copying or creating documents where partner assignments are involved.
  When customizing or assigning partners in partner determination procedures.
