When I'm updating our data model, sometimes I want to "lift" a primary key out to a new, parent data set. For example, I have a "Web Conversion" table, which had a primary key of "Conversion ID". I'm lifting that up to it's own SQL data set, since other tables use the same conversion IDs, and I'd like a single model to relate them all (see image below). However, whenever I try to adjust a field to be a relationship instead of an attribute, it screws up any downstream dependencies (see pic). Is there not a way to do this w/o screwing up all my insights, metrics, and dashboards?
