How To Fix DBGEXT030 - Breakpoints for user &1 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: 030

• Message text: Breakpoints for user &1 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 user &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 of
user &V2& 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 of user &V1&
hitting a breakpoint are debugged by a debugger launched in your current
logon session.

• What is the cause and solution for SAP error message DBGEXT030 - Breakpoints for user &1 have already been set by another logon session. ?

  The SAP error message DBGEXT030 indicates that breakpoints have already been set for a specific user in another logon session. This typically occurs when a user is debugging an ABAP program and tries to set breakpoints while another session is already active with breakpoints set for the same user.
  Cause:
  
  Multiple Sessions: The user has multiple sessions open in SAP, and breakpoints have been set in one of those sessions.
  Debugging Mode: The user is trying to debug a program while another debugging session is already active for the same user.
  User Lock: The debugging environment locks the user to prevent conflicts when multiple sessions are trying to set breakpoints.
  
  Solution:
  
  Close Other Sessions: Check if there are other active sessions for the same user. If so, close those sessions or log out of them.
  Remove Breakpoints: If you have access to the other session, you can remove the breakpoints from there. You can do this by:
  
  Going to the debugger in the active session.
  Navigating to the breakpoints and deleting them.
  
  
  Use a Different User: If possible, log in with a different user ID to set breakpoints without conflicts.
  Wait for Timeout: If you cannot access the other session, you may need to wait for the session to time out or be terminated by the system administrator.
  
  Related Information:
  
  Debugging in SAP: When debugging in SAP, it's important to manage breakpoints carefully, especially in a multi-session environment.
  Transaction Codes: You can use transaction codes like SM50 (to view active processes) or SM66 (to view global processes) to monitor sessions and processes.
  User Management: If you frequently encounter this issue, consider discussing with your SAP Basis team about user session management and debugging practices.
  
  If the problem persists after trying the above solutions, it may be beneficial to consult with your SAP Basis or technical support team for further assistance.
