ALLEXCEPT DAX Function in Power BI
The ALLEXCEPT DAX function removes all context filters on the table except filters that have been applied on the specified columns which are specified in the ALLEXCEPT function. It returns a table with all filters removed except for the filters on the specified columns.
DAX Syntax ALLEXCEPT(table, column[,column[,…]])
The function has the following parameters:
- table: The table over which all context filters are removed, except filters on those columns that are specified in subsequent arguments.
- column: The column for which context filters must be preserved. The column reference to the base table given in the first argument. It must be base columns and not column-expressions.
The first argument to the ALLEXCEPT function must be a reference to a base table. All subsequent arguments must be references to base columns. We cannot use table expressions or column expressions with the ALLEXCEPT function.
Example: Here in the formula, we are specifying that the measure is going to be filtered only based on the Name field of the Sheet1 table.
DAX
The output of the above measure is shown below:

In the above image we can see that the total measure value is shown in each row for all the countries even though we have filtered the countries by using slicer. So, it is not filtered based on Country field of the table.
At the same time, we can see that the measure is filtered on the Name field of the table.
