How To Fix DBGEXT031 - Breakpoints for this TID have already been set by another logon session.

SAP Error Message - Details

• Message type: E = Error

• Message class: DBGEXT - Low level Debugger Interface

• Message number: 031

• Message text: Breakpoints for this TID have already been set by another logon session.

What causes this issue?

You want to set a new external breakpoint or delete an existing one.
However, there are already external breakpoints for terminal ID &V1&,
set by user &V2&. But these were set in another logon session. The last
breakpoints have been set there &V3& hours and &V4& minutes ago.
That means that the current debugger activation for external requests
with the current terminal ID is assigned to this other logon session and
as a consequence the debugger for those requests is launched there.

System Response

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

How to fix this error?

You should decide whether you want to take over this debugger
activation. If you do so, all upcoming external requests tagged with
this terminal ID hitting a breakpoint are debugged by a debugger
launched in your current logon session.

• What is the cause and solution for SAP error message DBGEXT031 - Breakpoints for this TID have already been set by another logon session. ?

  The SAP error message DBGEXT031 indicates that breakpoints have already been set for a specific Transaction ID (TID) in another logon session. This typically occurs when multiple sessions are trying to debug the same program or transaction simultaneously, and the debugger is unable to handle multiple breakpoints for the same TID.
  Cause:
  
  Multiple Sessions: You have multiple SAP GUI sessions open, and at least one of them has set breakpoints for the same transaction or program.
  Shared Debugging: If you are working in a shared environment, another user might have set breakpoints for the same transaction.
  Debugging Configuration: Sometimes, the debugger settings or configurations might lead to this issue.
  
  Solution:
  
  Close Other Sessions: Check if you have other SAP sessions open that are debugging the same transaction. Close those sessions or remove the breakpoints in those sessions.
  Remove Breakpoints: If you have access to the other session, you can remove the breakpoints set there. You can do this by navigating to the debugger and clearing the breakpoints.
  Use a Different TID: If possible, try using a different transaction ID or program to debug.
  Log Off Other Users: If you are in a shared environment and have the necessary permissions, you may log off other users who are debugging the same transaction.
  Restart the Debugger: Sometimes, simply restarting the debugger or the SAP GUI can resolve the issue.
  
  Related Information:
  
  Debugging in SAP: When debugging in SAP, it is important to manage breakpoints carefully, especially in a multi-user environment.
  Transaction Codes: Familiarize yourself with transaction codes like /h to start debugging and BREAK-POINT statements in ABAP code.
  SAP Notes: Check SAP Notes for any specific patches or updates related to debugging issues, as there may be known issues or fixes provided by SAP.
