  Error Message
  VPD031: Specify partner number for function &1
  
  Cause
  This error occurs during the processing of partner functions in SAP, typically in sales and distribution (SD) or customer/vendor master data maintenance. The system expects a partner number to be specified for a particular partner function, but it is missing.
  
  Partner function refers to roles like Sold-to party, Ship-to party, Payer, Bill-to party, etc.
  The system requires that for certain partner functions, a partner number (customer/vendor number) must be entered.
  If the partner function is assigned but the partner number is not specified, this error is triggered.
  
  
  When does it occur?
  
  During sales document creation (e.g., sales order, delivery).
  When maintaining partner data in customer/vendor master.
  When partner determination procedures are in use and a required partner number is missing.
  During partner assignment in billing or shipping documents.
  
  
  Solution
  
  
  Specify the partner number for the indicated partner function:
  
  Check the partner tab in the sales document or master data.
  Enter the correct partner number for the partner function mentioned in the error message (the placeholder &1 will be replaced by the partner function code, e.g., AG for Sold-to party).
  
  
  
  Check partner determination procedure:
  
  Verify the partner determination procedure assigned to the document or master data.
  Ensure that the partner function is correctly configured and that the partner number is maintained.
  
  
  
  Maintain partner master data:
  
  If the partner number is missing because the partner does not exist, create the customer/vendor master record first.
  Then assign the partner number to the partner function.
  
  
  
  Check user input:
  
  If the error occurs during manual entry, ensure the user inputs the partner number for mandatory partner functions.
  
  
  
  Customization:
  
  In SPRO, check the partner determination procedure under:
  Sales and Distribution -> Basic Functions -> Partner Determination -> Set Up Partner Determination
  Make sure the partner function is set as mandatory if required.
