• What is the cause and solution for SAP error message SY072 - RTJ stack overflow for & ?

  The SAP error message SY072 indicates a "RTJ stack overflow," which typically occurs when there is a recursive function call that exceeds the allowed stack size. This can happen in various scenarios, such as when a program or function calls itself too many times without a proper exit condition, leading to a stack overflow.
  Causes:
  
  Recursive Function Calls: A function is calling itself without a proper base case or exit condition.
  Infinite Loops: A loop that does not terminate can lead to excessive stack usage.
  Excessive Data Processing: Processing large amounts of data in a single function call can lead to stack overflow.
  Configuration Issues: Incorrect configurations in the system or program logic that lead to unexpected behavior.
  
  Solutions:
  
  Review Code for Recursion: Check the code for any recursive function calls and ensure that there is a proper base case to terminate the recursion.
  Optimize Loops: Ensure that loops have proper exit conditions and are not running indefinitely.
  Break Down Functions: If a function is processing too much data, consider breaking it down into smaller, manageable pieces.
  Increase Stack Size: In some cases, increasing the stack size in the system configuration may help, but this is generally a workaround rather than a solution.
  Debugging: Use debugging tools to trace the execution of the program and identify where the overflow is occurring. Look for patterns in the call stack that lead to the overflow.
  Check for Updates: Ensure that your SAP system is up to date, as patches and updates may resolve known issues related to stack overflows.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues related to the SY072 error. SAP frequently publishes notes that provide solutions or workarounds for specific error messages.
  Transaction Codes: Use transaction codes like SE80 (Object Navigator) or SE37 (Function Module) to analyze the code and identify the source of the error.
  Performance Monitoring: Monitor system performance to identify any unusual behavior that may lead to stack overflow errors.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with SAP support or a developer with experience in debugging SAP applications.
