Using Filters

[Anonymous]

Hello

Is there a complete tutorial/guide on 'filtering' in PowerBI/DAX? Apart from the obvious visual filters?

I am figuring out how to use them (e.g. how to make All Page visual filters not to apply to a Measure with CALCULATE) but I then forget because it's not very straightforward.

Is there a definite and complete guide that I can refer to?

Thanks!

Hi @Anonymous ,

Here I will answer your question and give you some advise.

e.g. how to make All Page visual filters not to apply to a Measure with CALCULATE

Try ALL function, it will remove all filter from your report, and your measure won't be impacted by report filter / slicer.

Measure looks like as below.

Measure =
CALCULATE(
	SUM('Table'[Data]),
	ALL('Table')
)

You may refer to  the blog or video as below to learn more details.

@Anonymous Well, there is the Definitive Guide to DAX book, which is always good to have.

For example, this does not seem to work:

KPI = DISTINCTCOUNT(A[Column1])&" out of "&CALCULATE(DISTINCTCOUNT(A[Column1]),ALL(A[Column5])>TODAY()-7)

The True/False expression does not specify a column. Each True/False expressions used as a table filter expression must refer to exactly one column.
