A Look Behind the Curtain – Lift the veil from saplogon.exe (Part 1)

The SAP logon program saplogon.exe is the centre of rotation of all communication between the SAP GUI for Windows and the SAP application server. The SAP logon is the one and only. If you want to know more details about the activities of the saplogon.exe process, you have the possiblity to use Microsofts Process Monitor from Set the filter to the process name saplogon.exe.


If you activate the capture, you can see a lot of details of activities of the following operation areas:

  1. Access to the file system.
  2. Access to the registry.
  3. Monitoring of the process and its threads, also DLL and device driver access.
  4. Network activities.

With this way it is e.g. very easy to detect the procedure of the execution of a SAP GUI Script via the playback function of the SAP GUI Scripting recorder – see also here.
