Thanks for the reply.
I would like to it add as a dimension.
And yes, both fields are numeric.
I only have access on the database design not the SQL.
Main objective for this is to really filter our “0” stock in product_id and store_id level.
Which does not seem to be working if I create a filter at product_id with stock “>0” and another at store_id with stock “>0”. The value does not match-up when I downloaded the data without filters, and manually check the total stock “>0”, vs. to what I downloaded with the filters. So I thought I could add a new dimension and filter with this.
