Warehouse catalogue enables us to select tables we want to have in a microstrategy project. While creating a project through project creation assistant, it will guide through warehouse catalogue. Also we can load warehouse catalogue from microstrategy desktop -> Schema Menu
So warehouse catalogue can also be used for removing a table from the microstrategy project. In the right pane we will see all the objects that are selected in the microstrategy project. We can right click on an object to see the sample data, to find out the row count and to see the table structure.
