• What is the cause and solution for SAP error message RLB075 - Library &1 is called recursively ?

  The SAP error message RLB075 ("Library &1 is called recursively") typically occurs when a function module or method is called in a recursive manner, leading to an infinite loop or excessive depth of calls. This can happen in various scenarios, such as when a function module calls itself directly or indirectly through other function modules.
  Cause:
  
  Direct Recursion: A function module or method is directly calling itself without a proper exit condition.
  Indirect Recursion: A function module calls another function module, which in turn calls the first one, creating a loop.
  Improper Logic: The logic within the function may not have a proper termination condition, leading to repeated calls.
  Configuration Issues: Sometimes, configuration settings or custom developments can lead to unexpected recursive calls.
  
  Solution:
  
  Review the Code: Check the implementation of the function module or method that is causing the error. Look for any direct or indirect calls to itself.
  Add Termination Conditions: If recursion is intended, ensure that there are proper termination conditions to prevent infinite loops.
  Debugging: Use the ABAP debugger to trace the call stack and identify where the recursion is happening. This can help pinpoint the exact location in the code.
  Refactor Code: If recursion is not necessary, consider refactoring the code to use iterative logic instead of recursive calls.
  Check for Configuration Issues: If the error is related to a specific configuration, review the settings and ensure they are correct.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to the specific function module or method you are working with.
  Documentation: Review the documentation for the function module or method to understand its intended use and any limitations.
  Performance Considerations: Recursive calls can lead to performance issues, so it's essential to evaluate whether recursion is the best approach for your use case.
  
  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 function module or method in question.
