Bug 181355 Cross tab layout behavior
- add a cross tab item - try to drag and drop a level from the cube( in data explorer ) into the cross tab layout Currently this is not supported. User can only drag dimension nodes. Expected behavior - User should be able to drag level nodes too, this should actually add dimension to the cross tabl row/column area
