Your realizations are a translation of the requirements model to the
analysis/design model. Don't correlate your logical view packages with Use
Cases. It's perfectly fine to have a Use Case realization use classes that
exist in many different packages. Therefore, try the following:
-in the Logical View, create a Use Case realizations package.
-create a Use Case realization for each Use Case.
-create your diagrams that show the participation of the objects that
fullfill a Use Case. This will be a set of interaction diagrams for each Use
Case flow of events, and a class diagram illustrating the view of
participating classes for that Use Case.
-keep in mind that any relationships that exist among the classes need to
coincide with any package dependencies that may have been defined.
All of this is separate from your actual subsystem packages.

> Hello,
>
> While doing the architecture for our system I came across the following
> problem, which I'll describe in general terms:
>
> I have a use case UC1.
> The sequence diagram of UC1 shows 2 analysis classes A, and B.
> The architect decided to put class A in sub-system SSa and class B in SSb
> (i.e. two separate packages in the Logical View, each with its own
> analysis
> classes).
> Now I want to make the use case realisation (diagram) of UC1. What do I
> do?
> Put it in SSa and use class B in SSa? The consequence is that looking at
> SSb it is very hard to see that one of its analysis classes participates
> in
> the realisation of UC1.
> Or is it possible that UC1 be realised by 2 -incomplete- use case
> realisations, one in each subsystem?
