How can I select data from two columns in different tables, in a column for a third table through relationships?
I'm using SSAS.
Like this:
Hey,
you could use the DAX function RELATED (https://msdn.microsoft.com/en-us/query-bi/dax/related-function-dax) when creating a calculated column and all the tables are related. It seems somewhat peculiar (at least for a Power BI datamodel) that table B is related to both tables (A and C) using column [ID].
It's more common to create a star schema in Power BI.
Maybe you can consider to create a relationship between table A and C, a 1 to 1 relationship.
Hopefully this gives you some ideas
Regards
Tom
