  Meaning / Cause
  This error occurs when the system tries to assign or reference a business partner (such as a customer, vendor, or contact person) for a specific partner function in a document or master data record, but the partner number found does not exist in the master data.
  In other words:
  
  The system found a partner number assigned to a partner function.

  Business partner roles in SAP CRM or S/4HANA
  
  
  Solution / How to fix
  
  
  Check the partner number:
  
  Verify the partner number assigned to the partner function.
  Make sure the partner number exists in the relevant master data (Customer master, Vendor master, or Business Partner master).
  
  
  
  Create or maintain master data:
  
  If the partner number does not exist, create the master data record for that partner.
  Use transaction codes like:
  
  XD01 / VD01 for Customer master creation
  XK01 for Vendor master creation
  BP for Business Partner creation (in S/4HANA or SAP CRM)
  
  
  
  
  
  Correct the partner assignment:
  
  If the partner number is incorrect, correct it in the document or master data.
  Use partner determination or partner assignment screens to update the partner number.
  
  
  
  Check partner determination procedure:
  
  Review the partner determination procedure configuration to ensure correct partner functions and partner numbers are assigned.
  Use transaction VOPA or SPRO to check partner determination settings.
  
  
  
  Data consistency check:
  
  Run consistency checks or reports to identify missing or incorrect partner master data.
  If data was migrated, verify the migration steps and data completeness.
