If you have the Absences Administrators role, you will see a link to 'Holiday Plans' via the control panel, under the configuration menu.
If you select this link you will be taken to the 'Manage Holiday Plans' page where you can quickly create, edit, adjust and delete plans for groups of people and/or individual users.
Simply click the button ‘Select users or groups’ which will allow you to pick the user or group for which you wish to manage plans.
Once selected, you’ll see any plans associated with those selected. If they have one, then the plan can be edited using the options on the right hand side. If they don’t have one, you'll be provided with a simple interface to create one for them.
