TT313 - Details

• The SAP error message TT313 "Loop overflow" typically occurs in the context of SAP ABAP programming, particularly when there is an issue with recursive function calls or excessive looping in the code. This error indicates that the system has detected a loop that has exceeded the maximum allowed iterations, leading to a potential infinite loop situation.
  Causes:
  
  Excessive Recursion: A function or method is calling itself too many times without a proper exit condition.
  Infinite Loops: A loop structure (like a DO, WHILE, or FOR loop) does not have a valid termination condition, causing it to run indefinitely.
  Data Structure Issues: Problems with data structures that lead to unexpected behavior in loops, such as circular references.
  Incorrect Logic: Logical errors in the code that prevent the loop from terminating as expected.
  
  Solutions:
  
  Review Code Logic: Check the logic of the loops and recursive function calls to ensure that they have proper exit conditions.
  Limit Recursion Depth: If recursion
