You can permanently delete a warehouse group from the Data Warehouse Center; if you do so, the warehouse group definition will no longer exist in the Data Warehouse Center.
To remove a warehouse group definition:
From the Data Warehouse Center tree, expand the Administration folder, then expand the Warehouse Users and Groups folder.
Click the Warehouse Groups folder. Any existing warehouse groups are displayed in the pane on the right side of the window (the contents pane).
In the contents pane, right-click the warehouse group that you want to remove and select Remove from the pop-up menu. A confirmation window opens.
Click OK.
The warehouse group icon and its associated definition are deleted.
