Any time requests entered for the lesson (in the lesson row) or the elements involved in the lesson are highlighted with their appropriate colour code. Time requests entered under the master data of a subject are displayed in a separate row. The example shows that a time request has been entered for subjects "DS" and "HE".
If you have entered unspecified time requests, you can assign these a different colour in the time request window (e.g. purple for -3 for class 3b).

Time requests entered under master data or lessons can be deleted direct in the scheduling dialogue by clicking on the <Delete period> button or by pressing the <Delete> key, or modified in the time request window.
