Normally CBS Administrators should not delete buildspaces in CBS Web UI. Deleting a single buildspace may put the development landscape into an inconsistent state. Instead the “delete track” function of the Change Management Service (CMS) should always be used. Deleting a CMS track automatically deletes the associated buildspaces.
If the track deletion in CMS should fail for some reason, CBS administrators can delete a buildspace manually.
...
1. Start the CBS Web UI.
2. Navigate to the Buildspaces view.
3. Select a buildspace to delete.
4. Choose Delete.
