• What is the cause and solution for SAP error message VPD035 - Partner &1 already exists as &2 ?

  Certainly! Here's a detailed explanation for the SAP error message VPD035: Partner &1 already exists as &2:
  
  Error Message
  VPD035: Partner &1 already exists as &2
  
  Cause
  This error occurs when you try to assign or create a partner function in a sales document (such as a sales order, delivery, billing document, etc.) or in master data, but the partner number you are trying to assign already exists under a different partner function.
  
  &1 = Partner number you are trying to assign.
  &2 = Partner function under which this partner number already exists.
  
  In other words, the system prevents duplicate assignment of the same partner number to multiple partner functions where it is not allowed.
  
  When does it occur?
  
  During sales document processing (VA01, VA02, VA03).
  When maintaining partner functions in customer master or vendor master.
  When copying or creating documents where partner data is copied.
  When customizing or assigning partner functions in configuration.
  
  
  Explanation
  In SAP SD (Sales and Distribution), each partner function (e.g., Sold-to party, Ship-to party, Bill-to party, Payer) is assigned a partner number (customer/vendor). The system expects that a partner number is uniquely assigned to a partner function in a document or master data record.
  If you try to assign the same partner number to two different partner functions where this is not allowed, the system throws this error to avoid ambiguity in partner roles.
  
  Solution / How to fix
  
  
  Check existing partner assignments:
  
  Go to the sales document or master data where you are trying to assign the partner.
  Check the partner tab to see under which partner function the partner number already exists.
  
  
  
  Remove or change the duplicate partner assignment:
  
  If the partner number is assigned to a wrong partner function, delete or correct it.
  Assign the partner number only to the correct partner function.
  
  
  
  Use different partner numbers:
  
  If the business scenario requires the same partner number in multiple roles, check if this is allowed.
  Sometimes, the same partner number can be assigned to multiple partner functions, but only if the configuration allows it.
  If not allowed, use different partner numbers for different roles.
  
  
  
  Check partner determination procedure:
  
  Review the partner determination procedure in customizing (SPRO ? Sales and Distribution ? Basic Functions ? Partner Determination).
  Ensure that the partner functions and partner determination procedures are correctly configured.
  Sometimes, partner determination procedures restrict duplicate partner assignments.
  
  
  
  Check for user-exits or enhancements:
  
  Custom code might be enforcing additional checks.
  Review any user-exits or BAdIs related to partner assignment.
