Open the selected document in the tab marked with a question mark (tile on the left side). Hover the cursor over the field in the ABSENCES column until a plus icon appears, then click it. If the schedule is in edit mode, a message will appear—confirm it. Select the appropriate absence from the displayed list and confirm by clicking OK. Enter the absence details, such as date, hours, comment, or attachment, and then confirm the entered data. The absence will be added to the schedule.
For more information, see the article: Absence planning.

In the mobile app, an absence can be added directly from the schedule view. Simply tap the floating action button and select Absence. Then choose the appropriate type of absence from the list, fill in the details such as date, hours, comment, or attachment, and finally confirm the entered information by tapping OK. Once saved, the absence will automatically appear in the schedule.
