• What is the cause and solution for SAP error message TK813 - Too many recursive calls (> &1) in &2 ?

  The SAP error message TK813 indicates that there are too many recursive calls in a particular program or function module, exceeding the defined limit. This typically occurs when a function or method calls itself directly or indirectly in a way that leads to an infinite loop or excessive recursion depth.
  Cause:
  
  Recursive Function Calls: The most common cause is a function or method that calls itself without a proper exit condition, leading to an infinite loop.
  Circular Dependencies: If two or more functions call each other in a circular manner without a proper termination condition, it can lead to excessive recursion.
  Configuration Issues: Sometimes, configuration settings or incorrect logic in the program can lead to unexpected recursive calls.
  Data Issues: Input data that leads to unexpected behavior in the logic of the program can also cause excessive recursion.
  
  Solution:
  
  Review the Code: Check the function or method that is causing the recursion. Ensure that there is a proper exit condition to prevent infinite recursion.
  Debugging: Use debugging tools to trace the function calls and identify where the recursion is happening. Look for the call stack to see how many times the function is being called.
  Refactor Code: If necessary, refactor the code to eliminate unnecessary recursive calls. Consider using iterative approaches instead of recursion if applicable.
  Increase Recursion Limit: If the recursion is valid and necessary, you may consider increasing the recursion limit in the system settings, but this is generally not recommended as a first solution.
  Check for Circular Calls: Ensure that there are no circular calls between functions that could lead to excessive recursion.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to the specific function or module you are working with.
  Performance Considerations: Excessive recursion can lead to performance issues and stack overflow errors, so it’s important to address the root cause.
  Testing: After making changes, thoroughly test the program to ensure that the recursion behaves as expected and does not lead to further issues.
  
  If the problem persists after trying the above solutions, consider reaching out to SAP support or consulting with a developer who has experience with the specific module or function in question.
