Defining source and target for relationship matrix

[nexdev]

Hi

I have created a model to describe some customer and product requirements, with views within the model root node as follows:

• Customer A's requirements
• Customer B's requirements
• Product requirements

All customer requirements are described using requirement elements, but product requirements are described using both requirement and usecase elements. I have defined realize relationships between product and customer requirements and would like to create a relationship matrix for each set of customer requirements to show the relationship between customer and product requirements.

The problem that I have is that I can't find a way of defining the relationship matrix so that, for example, Customer A's requirements are the source and the Product requirements (requirement and usecase elements) are the target that gives me the result I need. Choosing a package to define the source and target includes elements that I don't need, e.g. actors and packages, and using a search (which can restrict the results to requirement and usecase elements) doesn't seem to allow a starting point in the model hierarchy to be defined, so I get both customer and product elements returned by the search.

Is there a way to do this?

Thanks
