Prerequisites
You know the process you want to record and the applications you require.
Procedure

If necessary, switch off the quick infos and the personal input help temporarily in each application to avoid these unnecessary elements being included in the recording.

In SAP R/3, for example, you make these settings under Customizing of local layout ® Options and Local Data.

Applications in the Applications to be recorded window are marked with a square:
Blue square: application is open and ready for recording.
White square: application is not open. The application is recorded as soon as it is opened.

If you want to record an R/3 System, select the SAP Logon application. If you use an older SAP GUI version (4.6D and below), select instead the FRONT application.
Result
You have made the required preparations and can record the tutorial (see
Recording Tutorials).
