How To Fix VY017 - Recursive call: Routine &1, Stack &2, Maximum &3

SAP Error Message - Details

• Message type: E = Error

• Message class: VY - Messages for freight processing

• Message number: 017

• Message text: Recursive call: Routine &1, Stack &2, Maximum &3

What causes this issue?

The routine as been called recursively.
The maximum nesting depth (stack) has been exceeded.

System Response

To prevent the recursive call of the routines becoming a loop,
processing was terminated after a maximum number of calls.
The maximum number of recursive calls is specified in the routine.

How to fix this error?

Check whether the data processed is consistent. If necessary, increase
the maximum number or recursive calls.

• What is the cause and solution for SAP error message VY017 - Recursive call: Routine &1, Stack &2, Maximum &3 ?

  The SAP error message VY017 indicates a recursive call in a routine, which means that a function or routine is calling itself either directly or indirectly, leading to a stack overflow. This can happen in various scenarios, such as during the execution of a user exit, a BAdI implementation, or a custom program.
  Cause:
  
  Recursive Function Calls: The most common cause is that a function or routine is designed in such a way that it calls itself without a proper exit condition.
  Circular Dependencies: If two or more routines call each other in a circular manner, it can lead to infinite recursion.
  Incorrect Logic: Logic errors in the code can lead to unintended recursive calls.
  Configuration Issues: Sometimes, configuration settings in the system can lead to unexpected behavior in custom routines.
  
  Solution:
  
  Review the Code: Check the routine mentioned in the error message (indicated by &1) for any recursive calls. Ensure that there is a proper exit condition to prevent infinite recursion.
  Debugging: Use the debugger to trace the execution flow and identify where the recursive calls are happening. This can help pinpoint the exact location of the issue.
  Refactor Code: If recursion is necessary, consider refactoring the code to use an iterative approach instead of recursion, if possible.
  Check for Circular Calls: If multiple routines are involved, check for circular dependencies and modify the logic to avoid them.
  Test Changes: After making changes, thoroughly test the routine to ensure that the error does not occur again and that the functionality remains intact.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues related to the specific version of SAP you are using. There may be patches or updates that address this issue.
  Performance Considerations: Recursive calls can lead to performance issues, so it's essential to ensure that the logic is optimized.
  Documentation: Review the documentation for any user exits or BAdIs you are using to understand their intended behavior and any limitations.
  
  If the issue persists after following these steps, consider reaching out to SAP support or consulting with a developer who has experience with the specific routines in question.
