There are a number of merge unit restrictions.
Note these restrictions for merge units:
- After a graphical merge, referenced model elements
that are not accessible are displayed as "unresolved" in the resulting
sequence diagram. For example, model elements that are outside of IBM® Rational® Rhapsody® but
referred to by diagram elements inside Rational Rhapsody refer
are displayed as "unresolved").
- Model elements cannot be edited in diagram graphical
merge mode.
- Many of the model diagrams are displayed in read‑only
mode except for merged statecharts, activity diagrams, and sequence
diagrams. Therefore, some product functionality is not available in
read‑only diagram views, for example:
- Movement
- Changing the element properties
- Opening referenced diagrams
