You can block a room from automatic scheduling if it is unavailable at certain times because, for example, it is in use by another school.
Example: Room SH1 is used by another school on Mondays and Thursdays from the 6th to 8th periods and on Friday mornings.
| 1. | Select SH1 in the list of the rooms by clicking on it. |
| 2. | Click on the button <Time requests>. |
| 3. | Click on the <-3> button. |
| 4. | Select the periods in which you wish to block the room by marking them while holding the left mouse button pressed. |

The time request –3 blocks the rooms completely, i.e. optimisation will not schedule lessons in the room in the periods specified.
