Hi,
I'm trying to create a relationship between 2 dimensions in analysis services. I found this link which tells me how to do this:
https://docs.microsoft.com/en-us/analysis-services/tabular-models/create-a-relationship-between-two-tables-ssas-tabular?view=asallproducts-allversions
I opened the project with Visual Studio (with SQL Server Data Tools installed), but I couldn't find the Model menu that the above link states. Below is a screenshot of what I currently see (I've masked out the table / dimension names):

I was wondering if there's another way to create relationships between dimensions in SSAS? Is there a setting I need to change in order to make the Model menu appear (as per the link above). Thanks!
Sincerely,
Jason
