All() function doesn't work properly in calculate function

Hi Anonymous ,

It may be that your data is too complex generating auto-exist reactions.

The normal behavior for DAX expressions containing the ALL() function is that any filters applied will be ignored. However, there are some scenarios where this is not the case because of auto-exist, a DAX technology that optimizes filtering in order to reduce the amount of processing required for certain DAX queries. An example where auto-exist and ALL() provide unexpected results is when filtering on two or more columns of the same table (like when using slicers), and there is a measure on that same table that uses ALL(). In this case, auto-exist will merge the multiple filters into one and will only filter on existing combinations of values. Because of this merge, the measure will be calculated on the existing combinations of values and the result will be based on filtered values instead of all values as expected.
