• What is the cause and solution for SAP error message WZ166 - Result dependent on a check function module ?

  Certainly! Here's a detailed explanation regarding the SAP error message WZ166 - Result dependent on a check function module:
  
  SAP Error Message: WZ166
  Text: Result dependent on a check function module
  
  Cause
  This message typically appears in the context of SAP Workflow or Business Rules Framework plus (BRFplus) or during custom validations where the outcome/result of a process or decision depends on the execution of a check function module.
  
  The system is indicating that the result of a current operation or decision is not fixed but depends on the evaluation of a check function module.
  This usually means that the system is calling a custom or standard function module designed to perform some validation or check, and the final result depends on the output of this function.
  The message can appear if the function module returns a certain status or if the workflow/rule engine is configured to show this message as an informational or warning message.
  
  
  When does it occur?
  
  During workflow processing, when a step's outcome depends on a function module that performs checks.
  In custom validations or user-exits/enhancements where a function module is called to validate data or business logic.
  In BRFplus rules or decision tables where a function module is used as a condition or expression.
  When a result or status is not directly determined by the system but by the logic inside the function module.
  
  
  Solution / How to handle it
  
  
  Check the Function Module:
  
  Identify the function module mentioned or involved in the process.
  Review its code and logic to understand what checks it performs and what results it returns.
  Ensure the function module is working correctly and returning expected results.
  
  
  
  Review Workflow or Rule Configuration:
  
  If this message appears in a workflow, check the workflow step or container element that calls the function module.
  Verify the conditions or decision logic that depend on the function module's output.
  Adjust the workflow or rule logic if necessary to handle the function module's results properly.
  
  
  
  Debugging:
  
  Use transaction SWI1 or SWI2_DIAG to trace workflow logs.
  Debug the function module to see what input it receives and what output it returns.
  Check if the function module raises any exceptions or returns unexpected values.
  
  
  
  Check Message Handling:
  
  Sometimes, this message is informational and does not indicate an error.
  If it is causing issues, check if the message class and number can be suppressed or handled differently in the workflow or program.
  
  
  
  Consult Documentation or SAP Notes:
  
  Search for SAP Notes related to the function module or the workflow template.
  Check if there are known issues or patches available.

  Summary
  
  WZ166 indicates that the result of a process depends on a check function module.
  It is usually informational but points to a dependency on a function module's logic.
  To resolve or understand it, review the function module, workflow/rule configuration, and debug as needed.
