Need help with used DC model

Hi all,

I've created 2 localdevelopment projects.

One mainproject and one models project.

In the models project i created a public part for a rfc model.

I add this public part to my Used DCs of my mainproject.

Now I want to use this model in this project bud I don't know how to do that.

When I choose add from the context menu from "Used Models" I can't find him there.

Please help, what am i doing wrong?
