Allow multiple form instances
Select this check box to allow the user to open more than one instance of a window. Clear this check box to prevent the user from opening more than one instance of a single window.
For example, a user with this setting can select Purchasing > Purchase Requests > Enter multiple times to open multiple instances of the Purchase Requests Enter window and work on multiple purchase requests simultaneously. A user without this setting can only open a single Purchase Requests Enter window.
This check box is selected by default for new users.
