After Jet InsideNAV has been installed and configured and you have been using it for a while, you may want to select different objects from the Jet Analytics Data Warehouse to include in Dynamics NAV.
To remove an object from InsideNAV, following these steps:
From within Dynamics NAV, go to Departments and then to Jet InsideNAV
Select Jet SQL Object
In the Jet NAV SQL Object List, select the table(s) you wish to remove and then click Remove Object (located on the Home tool ribbon)
This will mark the object(s) in the Object Designer with DELETE in the Version List, and the object(s) will be available to be deleted.
