Smart SAP Assistant

• What is the cause and solution for SAP error message AMDP_DBG031 - Debugging for connection "&1" already in use by user "&2" client "&3". ?

  The SAP error message AMDP_DBG031 indicates that a debugging session for a specific connection is already in use by another user. This typically occurs when multiple users attempt to debug the same ABAP Managed Database Procedure (AMDP) or when a single user tries to initiate a debugging session on the same connection that is already being debugged.
  Cause:
  
  Concurrent Debugging: Another user is already debugging the same connection.
  Session Overlap: The same user may have multiple debugging sessions open for the same connection.
  Connection Lock: The connection might be locked due to a previous debugging session that hasn't been properly closed.
  
  Solution:
  
  Check Active Sessions: Verify if another user is currently debugging the same connection. You can use transaction SM50 or SM66 to check active processes and see if someone else is using the debugger.
  Terminate Other Sessions: If you have access, you can terminate the other debugging session using transaction SM50 or SM66. Be cautious with this approach, as it may disrupt another user's work.
  Wait for Release: If you cannot terminate the other session, you may need to wait until the other user finishes their debugging session.
  Use a Different Connection: If possible, try to use a different connection or client to debug your AMDP.
  Close Unused Sessions: Ensure that you close any debugging sessions that you are not actively using to avoid locking issues in the future.
  
  Related Information:
  
  Debugging AMDP: When debugging AMDPs, it's important to manage your sessions carefully, especially in a multi-user environment.
  Transaction Codes: Familiarize yourself with transaction codes like SM50 (Process Overview) and SM66 (Global Process Overview) to monitor and manage active sessions.
  User Management: Ensure that user roles and permissions are set correctly to avoid unauthorized access to debugging sessions.
