DAX REMOVEFILTERS vs ALL

Question

How to substitute REMOVEFILTERS in the following code with old school functions ALL and VALUES instead? This exercise is just to better understand REMOVEFILTERS.

Answer 1

REMOVEFILTERS is just an alias of ALL here, so it works just the same.

Basically, ALL returns a table including all rows, ignoring any filters that might have been applied.

However, when ALL is used as a filter argument of CALCULATE or CALCULATETABLE, it behave totally differently: it removes filters from the table and does not return a table.

To alleviate this confusing behavior of ALL, REMOVEFILTERS was introduced to replace ALL when it is used inside CALCULATE.
