Quickly setup users to perform more than one role within your operation!
What happens if one role gives the user permission to do something and the other role does not?
If any of the roles give the user permission to do something, the user gets permission to do it.
Here's an example of why you would add a user to more than one role:
Let's say you have an Instructor Role setup with the following permission: "Yes, this user can edit student's reservations.
You have a user named Betty that is assigned to the Instructor Role and therefore is able to "edit student's reservations."
You also have a Front Desk Role that has the following permission: "Yes, this user can dispatch aircraft."
Now let's say you also want Betty to help perform all front desk tasks in addition to her instructing tasks. To give Betty of the Front Desk Role permissions, simply assign Betty to the Front Desk Role also. The result, in this example, is that Betty will have permission to both "edit her student's reservations" as well as "dispatch aircraft."
To assign a user to more than one role you can edit the user's role assignment or use the tool for assigning mass users to roles which makes it easy to move/copy a user to a different/additional role.
Keep in mind, the less roles you assign a user to, the easier it is to understand where the user is getting their permissions. Therefore, it is recommended that you only assign users to multiple roles when it is completely necessary. It is usually unnecessary to assign a user to multiple roles that have many overlapping permissions.
