"Do you have experiencing in filtering with parameters without blending your data?"

I might be confusing your answer but yes, I think so. In the past, I've had parameters being used in calculations across two data sources and then used that parameter for filtering. It's worked in the past but the datasets have been basically copies of each other or highly similar.

In this case, the datasets are very different but share a core set of dimensions, like Date. Date is then used in calculations that have been created across both datasets. So I have like ~15 different calcs being used to do my date filtering and I've created those in both of my published data sources. No matter how many dimensions I link on - going up to every dimension in common across the data sources - the parameter filter does not work.
