Importing Tabular Model in PowerBI Dektop

Hi everyone,

I have an issue, importing a Tabular Model into Power BI Desktop. I have read about similar questions within this forum, however I think my question is slightly different:

I have made a Tabular Model, in which I inserted some tables with relevant data. Within the model, we created some relations between the different tables. 
I want to import this Tabular Model into Power Bi, keeping the relations that we have created in the original model. However, when I import the Tabular Model, I lose the relations that I created, thus getting different results, in relation to the results that I obtain, when I extract the results directly from the Tabular Model (which is the option Live Connect)

I do need to use the Import option, since the reports that I deliver are published outside my organization, thus not being able to Live Connect with the Tabular Model. 

My question is: " is there a possibility to import a Tabular Model in PowerBI, which contains the original relations created within it? If yes: what are the steps to take, to be able to succesfully import the Tabular Model as described above?

Thanks for your reply!
Kind regards,
Jurgen van Geest
