How To Fix FDT_SERVICE180 - Recursion error in application exit class &1 method &2 for id &3

FDT_SERVICE180 - Overview

• Message type: E = Error

• Message class: FDT_SERVICE - Formula & Derivation Tool: Services

• Message number: 180

• Message text: Recursion error in application exit class &1 method &2 for id &3

What causes this issue?

BRFplus has detected a deep recursion for the call of an application
exit method. To prevent endless runtime and eventually a stack overflow,
BRFplus issues an exception in case the application exit method is
called more than 3 times recursively for the same object ID.
Such a situation might e.g. occur, if the application exit reacts on the
change of a BRFplus object. If the implementation performs again a
change on the object, this will cause yet another call of the same
application exit. Unless there's a condition that stops changing the
same object again and again, this would lead to endless recursion.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

System Response

A CX_FDT_SYSTEM exception is thrown.

How to fix this error?

The implementation of the application exit must ensure that it is not
causing unintended recursion.

Procedure for System Administrators

Contact the owner of the application exit class.

FDT_SERVICE180 - Details

• The SAP error message FDT_SERVICE180 indicates a recursion error in an application exit class. This typically occurs when a method is called recursively without a proper exit condition, leading to an infinite loop or excessive depth of method calls. Here’s a breakdown of the cause, potential solutions, and related information:
  
  Cause:
  
  Recursive Method Calls: The most common cause is that a method is calling itself directly or indirectly without a proper termination condition.
  
  Configuration Issues: Incorrect configuration of the application exit or the associated classes can lead to unexpected behavior.
  Data Issues: Sometimes, the data being processed can lead to unexpected recursive calls, especially if the data structure is not as expected.
  Custom Code: If there is custom code in the application exit, it may not be handling certain scenarios correctly, leading to recursion.
  
  
  Solution:
  
  Review the Code: Check the implementation of the method mentioned in the error message. Look for any recursive calls and ensure that
