Is it possible to mantain RELM product links to the DM model before changes were made in it?

Hi everybody,

I having problems with RELM , when I add link-s to Rhapsody DM model-s. When I add to a product a link to a DM model, and I make changes in the model, it does not mantain the previous state of the model. When I open the link, it opens the model but changed and it does not alert about that change, is it correct?

I hope someone can explain me why is this happening, pehaps it is not possible what I am trying to do.

Mikel
