You may want to copy an application that has relationships with other applications. If you are copying a detail application that has cross-application relationships, you have several options. You can:
Maintain the relationship in the copy
Remove the relationship in the copy
Grant clone access to the relationship in the copy
When you copy an application, you can choose to maintain its cross-application relationships in the new copy. When you choose this option, QuickBase creates a cross-application relationship between the new detail application and the Master Application specified in the original relationship. If you don't have admin permissions on the Master Application, you'll need to request these permissions for this relationship to work properly.
Note, however, that QuickBase does NOT add the new detail application (the new copy) to the cross-application permissions of the Master application.
You can also choose to remove any cross application relationships that exist when you copy an application. If you choose this option, you'll see that the relationship still exists in the copy; however, it is disabled. If you look at this relationship on the Relationships tab, you'll find that the relationship goes to an "Unknown Table" in the Master Application, as shown below. Later, if you change your mind, you can re-enable these relationships.

You'll see this choice only if you have Administration permissions on the Master Application. Selecting this choice will maintain the cross-application relationship in the copy, but will also add the copy to the Cross-Application Permissions of the Master Application. After copying the application, you'll see the new copy listed in the cross-application permissions for the master application:

To copy an application with a cross-application relationship:
Open the detail application that you want to copy.
In the menu bar on any application page, do one of the following:
Select Customize > Application and click the Management tab. Then click Copy application. If this command is not listed, then the app manager has not granted you permission to copy the application.
Or select Customize > Import/Export and click the Copy this application radio button, then click the Copy This Application link.
Enter a new name and description (optional) for the application.
Specify whether QuickBase should copy the application data, users, and roles when it makes the copy. (See Copy an Application with Data for more information.)
Tell QuickBase what to do with the cross-application relationships when it makes the copy. Choose one of the following:
Maintain cross-app relationship
Remove cross-app relationship
Grant clone access to the cross app
Click Copy Application. QuickBase creates and opens the application copy.
Once you've created your copy, you may want to take some additional steps:
Invite users. Even if you chose to grant users of the original application access to the new one by leaving their roles in place, you should bring the new application to their attention. If so, go to the Manage Users page and invite them.
Activate existing emails. When QuickBase copies your application, it copies any automated emails you've set up, but deactivates them in the new application. If you want QuickBase to start churning out emails from your new application, you must activate them. (Read how to activate and deactivate notifications, subscriptions and reminders.)
Note: If the application you're copying has a shared multiple-choice list that points to field in an outside application, the list will still draw from the field and application you specified when you set it up. However, if a shared multiple choice field points to a field within the same application, that shared multiple choice setup will be copied in its entirety. In other words, within the copied application, the shared multiple choice field points to the copied source multiple choice field. Read more about shared multiple choice fields.
