ALL function doesn't delete filter

[Anonymous]

Hello everyone!
I have very simple table 'Result' wich has columns Date_open, Date_close and Id.
I use two filters in dashboard: Date_open and Date_close
I want to create table with 2 columns:
1. Count Id with both filters: Date_close and Date_open
2. Count Id with one filters: Date_open

I have tried this code, which has to count id without filter on Date_close, but it doesn't work(( probably I don't understand ALL function correctly

CALCULATE (COUNT(result[id]), ALL(result[Date_close]))

NEVER use a single-table models. NEVER. They work counterintuitively and many a time will return wrong numbers without you even knowing it. Always use a proper star schema. ALWAYS.

Ignoring the above will result in you creating completely unreliable models that will calculate things you won't even be able to explain.

You shouldn't attempt these types of formulas without a Star Schema. Create lookup tables for both date columns and use those in your formulas and visuals. https://exceleratorbi.com.au/the-optimal-shape-for-power-pivot-data/
