is a temp table-like function possible?

[jim_lucht]

Hi Folks

I'm working with a large medical claims file in a Tabular data model in Connect Live mode and am looking for a way to get ALL claims for individuals who have ever had a particular procedure.

In SQL I would create a temp table with the person IDs of those who have had Procedure X and then join that back to the claims table to grab all claims under that person ID.

I've poked around quite a bit and haven't been able to find a solution. Perhaps there is a complex DAX function we can add to the Tabular Model that can add a flag field based on hard-coded value? Perhaps this is something that's easier to do by hitting the Tabular model with Dax Studio or the Excel plugin?

Many thanks for any help and ideas you can lend!

Hi @jim_lucht

The structure of what you are wanting to do is basically Basket Analysis:

http://www.daxpatterns.com/basket-analysis/

If you want to calculate specific measures filtered to claims for those individuals who have ever had a particular procedure, you could use the pattern on that page with a 'Filter Procedure' table with inactive relationship.

Possibly another approach would be to have a PersonID-Procedure bridge table, related to your PersonID column with a bidirectional relationship - haven't tried that before myself.

Cheers,

Owen
