• What is the cause and solution for SAP error message WSUBST024 - Error while calling the central determination logic ?

  The SAP error message WSUBST024: Error while calling the central determination logic typically occurs in the context of substitution and validation rules in SAP, especially when the system tries to execute a central determination (a kind of rule or logic that determines values automatically) and encounters an issue.
  
  Cause
  
  Incorrect or incomplete configuration of the central determination logic.
  The central determination logic (function module or BAdI) being called is not implemented or has errors.
  The custom code or standard logic used in the central determination contains syntax errors, runtime errors, or missing data.
  The context or data passed to the central determination logic is invalid or incomplete, causing the logic to fail.
  Missing or incorrect authorization for the user executing the logic.
  The central determination procedure is not assigned or activated in the relevant substitution or validation rule.
  
  
  Solution
  
  
  Check the substitution/validation rule configuration:
  
  Go to transaction GGB0 (Substitution) or GGB1 (Validation).
  Verify that the central determination procedure is correctly assigned and active.
  
  
  
  Analyze the central determination logic:
  
  Identify the function module or BAdI implementing the central determination.
  Check for any custom code errors or missing implementations.
  Use transaction SE37 to test the function module independently.
  Use transaction SE18/SE19 to check BAdI implementations.
  
  
  
  Check the input data:
  
  Ensure that the data passed to the central determination logic is complete and valid.
  Debug the substitution/validation process to see what data is passed and where it fails.
  
  
  
  Check authorizations:
  
  Verify that the user has the necessary authorizations to execute the substitution/validation and the central determination logic.
  
  
  
  Debugging:
  
  Set a breakpoint in the central determination function module or BAdI implementation.
  Run the transaction or process triggering the substitution/validation.
  Analyze the call stack and data to find the exact cause of the error.
