Manage Relationship and joining a table on a csv column.

[Anduve11]

In our datawarehouse we have a Product Table and a Tag Table.  One product can have multiple tags. I'm trying to figure out how to join the two based on the TagID column in the product table being a comma separated value.  I'm looking for help on how to possibly join these tables and/or if it's easier how to change the table structure in the warehouse to make this work.  My goal is to be able to have a drop down filter of all Tag Descriptions so that someone can pick a tag and see the product information that's tied to that tag.

Any advice on how to use tags in power bi and in data warehouse architecture would be greatly appreaciated.

Hi @Anduve11,

One easy solution could be splitting the TagID in the Query Editor. Then you can establish a relationship between these two tables.
