I would very much appreciate any help that can be offered on this, as I am unsure how to go about resolving. Thanks in advance.
Why does the null show? Is it possible to remove the null from showing in the filter?
Note: I tried to use a parameter that takes the inputs A or B, and a calculated field (below) to filter by, but this only ever returns the value "Drop" - maybe someone can enlighten me on this too?
IF ATTR([Source 2 (Example_Dataset)].[Baseline Source 2]) = [Baseline Parameter]
OR ATTR([Baseline Source 1]) = [Baseline Parameter]
Again, thank you for the help,
