There are three types of default data grid views:
  1. User Default View - your own default view
  2. Foundation Default View -   everyone's default view
  3. Default View - system default view
When you click on a tab in FIMS, the system determines what view it is going to display.  If there is a User Default View, that view will be displayed.  If not, it checks to see if there is a Foundation Default View.  If not, it will display the Default View.  So a User Default View has priority over both the Foundation Default View and the Default View. See Solution #25180 on how to create a User Default View.
