Now that you've created a Gaps template, you can apply it to the relevant weeks so you can send out your shifts or run the Autoscheduler.
In the 'Scheduler' click on 'Tools' and 'Apply gaps template'.
Select the location and template you want to apply, choose the date you want the template to start from, and how many weeks you want to apply it for.
Once you've hit 'Apply' the Gaps should appear in the Gaps row as specified. From here, you can either send out the Gaps notifications for employees or run the Autoscheduler.
