Changing a Hierarchy: Deleting Assignments  

To remove one or more objects from the hierarchy, proceed as follows:

...

       1.      Select the objects to be removed by positioning the cursor on each of the objects and activating Select/deselect node (for entity types) or Sel./desel. sub-tree (for data models).

       2.      Choose Modeling Object → Delete assignment.

The objects are automatically removed from the hierarchy.

You cannot remove an object from the hierarchy without also removing all its subordinate objects.

Delete assignment only removes objects from the data model hierarchy in question.
