This DAX Power BI tutorial explains the difference between ALL() and REMOVEFILTERS() Dax functions.
Usage of ALL() Dax Function: This function removes the applied filters from the current filter context.
Syntax: ALL ({table or column, [column], [column] …})
1 table The table that you want to clear filters .
2 column The column that you want to clear filters .
ALL() Syntax
Parameters used in Syntax of ALL.
For detailed explanation of ALL() Please see : Usage of ALL()
Usage of REMOVEFILTERS() Dax Function : It Clear filters from the specified tables or columns.
Syntax: REMOVEFILTERS ({table or column, [column], [column] …})
1 table The table that you want to clear filters .
2 column The column that you want to clear filters .
REMOVEFILTERS() Syntax
Parameters used in Syntax of REMOVEFILTERS.
Return Type :N/A. Please See remarks below.
REMOVEFILTERS can only be used to clear filters but not to return a table.
This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules
Differences between ALL() and REMOVEFILTERS()
REMOVEFILTERS is just an alias of ALL here, so it works in the same manner.
Basically, using only 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 / CALCULATETABLE, it behaves differently: it removes filters from the table and does not return a table.
To eliminate this confusing behavior of ALL, REMOVEFILTERS was introduced to replace ALL when it is used inside CALCULATE.
Lets take an example of the below code .
ALL Sales =
CALCULATE(
SUM(financials[ Sales]),
All(financials[Country])
)
Here All is an context modifier.
Usage of REMOVEFILTERS :Its an Alias for ALL when its used inside a CALCULATE modifier.
Advantage: RemoveFilters is faster than ALL and hence more efficient.
Disadvantages: Also Remove Filters cannot be used in DQ mode
