How To Fix DBGEXT002 - Another session (user &2) exists with global debugging scope for TID &1

SAP Error Message - Details

• Message type: E = Error

• Message class: DBGEXT - Low level Debugger Interface

• Message number: 002

• Message text: Another session (user &2) exists with global debugging scope for TID &1

What causes this issue?

There is already another logon session of user &V2& active, which has
system-wide debugging scope for request tagged with terminal ID &V1&.

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 select a local debugging scope so that you not interfere with
actions of the other logon session. If you continue, then there can be
unpredictable behavior and debugging may not work as you expect.

• What is the cause and solution for SAP error message DBGEXT002 - Another session (user &2) exists with global debugging scope for TID &1 ?

  The SAP error message DBGEXT002 indicates that another user session is currently using the global debugging scope for the specified transaction ID (TID). This typically occurs when multiple users attempt to debug the same program or transaction simultaneously, which can lead to conflicts.
  Cause:
  
  Concurrent Debugging: Another user (identified by user &2) is already debugging the same transaction or program with the same TID.
  Global Debugging Scope: The debugging session is set to a global scope, which means it affects all users and sessions, not just the one initiating the debug.
  Session Management: The system restricts multiple sessions from debugging the same transaction to prevent inconsistencies and conflicts in the debugging process.
  
  Solution:
  
  Identify the Other Session: Check which user is currently debugging the transaction. You can do this by using transaction SM50 (Process Overview) or SM66 (Global Process Overview) to see active sessions and identify the user.
  Wait for Release: If the other user is actively debugging, you may need to wait until they finish their debugging session.
  Terminate the Other Session: If you have the necessary authorizations and it is appropriate to do so, you can terminate the other user's debugging session. This can be done through transaction SM50 or SM66 by selecting the process and choosing to terminate it.
  Use Local Debugging: If possible, switch to local debugging instead of global debugging. This allows you to debug your session without interfering with others.
  Communicate with the Other User: If you know the user who is debugging, you can communicate with them to coordinate debugging efforts.
  
  Related Information:
  
  Debugging Modes: SAP provides different debugging modes, including local and global debugging. Understanding the differences can help in managing debugging sessions effectively.
  User Authorizations: Ensure that you have the necessary authorizations to terminate sessions or to debug programs.
  Performance Considerations: Be cautious when terminating sessions, as it may affect other users' work or lead to data inconsistencies.
  
  By following these steps, you should be able to resolve the DBGEXT002 error and continue with your debugging efforts.
