ADT Communication Log

Captures and displays every HTTP request and response between VS Code and SAP ADT in real time. Use it to diagnose slow operations, trace connection errors, or understand which ADT APIs the extension calls.

Start Logging

1. Open the Command Palette (Ctrl+Shift+P)
2. Run ABAP FS: Activate Communication Log
3. Select the SAP connection to monitor

The Communication Log panel opens at the bottom of the screen and immediately begins capturing traffic.

Stop Logging

Run ABAP FS: Deactivate Communication Log from the Command Palette.

Note: The log is held in memory only (up to 2000 entries). Entries are lost when you deactivate logging or close VS Code.
