Roles determine what a user can see and do inside an application. But what happens when roles collide? It's possible for a user to have multiple roles within the same application. For example, say a user belongs to two groups, and you've granted both groups access to your application but with different roles.
When a user has two roles, Quickbase grants the user access permissions allowed by either role. In other words, Quickbase adds up everything a user CAN do according to any role they're assigned and allows it. For example, if one role says they can't add a record and the other role says they can, Quickbase lets them add a record.
If you've designed a special data entry form for each role, and a custom app Home page too, dual roles present a real conflict. Because the program can only display one form or one Home page, it must choose a role. To do so, Quickbase checks to see which role has the higher priority and displays the form or app Home page associated with that role. Role priorities apply to all aspects of a role, including settings on the User Interface tab.
You can control which role takes precedence over another from within the application.
Important: Role priority is not supported when a user has both 1) access via a role assigned to the user, and 2) access via a role assigned to a group the user belongs to. This means that someone who has been assigned to a role is given priority over a person assigned using a group invite.
To set role priorities:
- From the app Home page, click Settings. 
- Click Roles. 
- Drag the roles into the order that you'd like them to appear in. Roles nearer the top of the list have precedence over roles further down in the list. - You can select more than one role using the checkbox to the left of the role name, then drag and drop all selected roles to reorder. While dragging, a horizontal red line indicates the place where the role(s) will be dropped. A tooltip gives exact information about the number of roles being dragged and the drop location. - If you prefer to sort the roles by a column in the list, click the column header to sort by that column. Drag and drop is disabled while you have roles sorted by a column, and a warning to that effect is displayed at the top of the screen. Click the Return to role list order link to re-enable drag and drop. - Note: Sorting the role list does not affect role priorities. 
- Test role settings to make sure each role behaves correctly after you've made your changes.
