Can Parameter Filter All Dataset?

Hi Anonymous ,

1. First of all, an optimized model of the star structure is a prerequisite for everything, which will avoid a lot of potential trouble.

2. I'm assuming that some tables are located where the crossfilter can't be passed, and you can use the crossfilter function in some MEASURES to appropriately adjust the crossfilter direction to be both-directional.

3. There doesn't seem to be a great way to do this for tables that don't have relational joins nor related fields.

There is a dynamic M query parameter under DirectQuery, but based on your description it doesn't look like it applies to your case.
