How To Fix 5W138 - Recursion check: & cannot be assigned

5W138 - Overview

• Message type: E = Error

• Message class: 5W - Messages for PD (Particularly Workflow)

• Message number: 138

• Message text: Recursion check: & cannot be assigned

What causes this issue?

When a task group is assigned to a different task group or role, the
system determines whether the object to be assigned (which can also
contain other objects) triggers recursion.
This is the case if creating the relationship leads to the same task
group occurring more than once in a hierarchical structure.

System Response

The system prevents you from creating the relationship.

How to fix this error?

Make sure that the object to be assigned, and/or its hierarchically
subordinate objects, do not occur in the object hierarchy currently
being processed.

Procedure for System Administrators

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

• What is the cause and solution for SAP error message 5W138 - Recursion check: & cannot be assigned ?

  The SAP error message 5W138, which states "Recursion check: & cannot be assigned," typically occurs in the context of ABAP programming when there is an attempt to assign a value to a variable that leads to a recursive situation. This can happen when a variable is defined in such a way that its assignment depends on itself, either directly or indirectly, which can lead to infinite loops or stack overflow errors.
  
  Cause:
  
  Direct Recursion: The variable is being assigned a value that directly references itself.
  Indirect Recursion: The variable is assigned a value that references another variable, which in turn references the original variable.
  Improper Logic: The logic in the program may be flawed, leading to unintended recursive assignments.
  
  
  Solution:
  
  Review Variable Assignments: Check the code where the variable is being assigned. Ensure that the assignment does not directly or indirectly reference itself.
  Refactor Code: If recursion is necessary for your logic, consider refactoring the code to
