The data needed in the forms can be found in a dialog box.

Click on the "magnifying glass"-icon to open a new window, where you can search for the needed data.

Usually, there is a CODE and a NAME in a dialog box. (For example: when searching for a student, the dialog box contains the student's ID and his/her NAME.)

If you know the CODE by heart, you can fill it in the appropriate field, and the system adds the NAME itself.

To use the dialog boxes, you need to enable the JavaScript in your internet browser!!!
