• What is the cause and solution for SAP error message VPD_DETERM_LOG008 - Mandatory function cannot be filled with '0' ?

  The SAP error message:
  VPD_DETERM_LOG008: Mandatory function cannot be filled with '0'
  
  Cause:
  This error occurs during the determination of partner functions in sales documents (e.g., sales orders, deliveries, billing documents) when a mandatory partner function is assigned an invalid or empty value, specifically '0'. In SAP SD (Sales and Distribution), certain partner functions (like Sold-to party, Ship-to party, Payer, Bill-to party) are mandatory and must be assigned valid partner numbers.
  The system tries to fill a mandatory partner function but finds the value '0', which is not a valid partner number. This usually happens due to:
  
  Incorrect or missing partner determination procedure configuration.
  Partner determination procedure assigns a partner function but the partner number is not maintained or is zero.
  Custom code or user exit/modification incorrectly sets partner function to '0'.
  Master data issues where the partner number is missing or zero.
  Incomplete or incorrect partner determination condition records.
  
  
  Solution:
  
  
  Check Partner Determination Procedure:
  
  Go to transaction VOPA (Partner Determination Procedures).
  Verify the partner determination procedure assigned to the sales document type.
  Ensure that mandatory partner functions are correctly configured and assigned.
  
  
  
  Check Partner Functions in Sales Document:
  
  In the sales document, check the partner tab.
  Make sure that mandatory partner functions have valid partner numbers assigned (not '0' or blank).
  
  
  
  Review Partner Determination Condition Records:
  
  Use transaction V/44 or V/45 to check condition records for partner determination.
  Ensure that the condition records do not assign '0' as a partner number.
  
  
  
  Check Master Data:
  
  Verify that the customer master data (transaction XD03, VD03, or FD03) is complete and valid.
  Ensure that the partner numbers used are active and valid.
  
  
  
  Debug or Review Custom Code:
  
  If there are user exits or BADIs related to partner determination (e.g., USEREXIT_MOVE_FIELD_TO_VBPA in MV45AFZZ), check if any code sets partner function to '0'.
  Correct the logic to assign valid partner numbers.
  
  
  
  Recreate or Adjust Partner Determination Procedure:
  
  If the procedure is corrupted or incorrectly maintained, recreate or adjust it.
  
  
  
  
  Additional Information:
  
  Partner functions are critical in sales documents for pricing, delivery, billing, and communication.
  The error prevents saving or processing the sales document because mandatory partner data is incomplete.
  This error is common when customizing or migrating data without proper partner assignments.

  Summary:
  
  Cause: Mandatory partner function assigned invalid partner number '0'.
  Solution: Correct partner determination procedure, assign valid partner numbers, check master data and custom code.
  Check: VOPA, sales document partner tab, condition records, customer master data, and user exits.
