When you want to edit a closed stock unit, ResBook will allow you to do so. Editing a closed room will allow you to change the date the room is closed for.
To edit a closure you must click on the closure you wish to edit on the calendar:
Then:
Old Calendar: hover over the closure and select [Edit closed Room] |  |
New Calendar: click on the closure and select [EDIT CLOSED ROOM] |  |
A pop-up screen will then appear:
Old Calendar: Make the appropriate changes and then select [CLOSE STOCK UNITS]. |  |
New calendar: Make the appropriate changes and then select [Submit]. |  |
Return to your calendar, and the changes should appear.
