Remove Filter Context to give aggregated count in table

Hi, 

 

I'm struggling with a really simple concept, and trying to get a measure which ignores initial filter context coming from a row in a table to correctly aggregate values. Screeshot below shoes the scenario. Basically want to go from table on the LHS to the table on the RHS. I understand why the Count becomes 1 for each MeetingID in the RHS table but am hitting a road block in getting the right DAX to give the 'Count Desired'. Any help much appreciated!

Re: Remove Filter Context to give aggregated count in table

try:

Count Desired = 
IF(
    COUNTROWS(FactMeetings) >0,
        CALCULATE(
            COUNTROWS(FactMeetings),
                 FILTER(
                     ALL(FactMeetings),
                     MAX( DimSalesePerson[Initials]) = FactMeetings[Initials]
                  )                      
        )
)

Re: Remove Filter Context to give aggregated count in table

Thanks @Nick_M , that works great! It was the MAX() part I was missing to try and redefine the required context. Though I can see the effect of removing the IF > 0 wrap around, I guess I don't fully understand the theory as why without it the filter between the tables seems to be multiplying out the columns.

Re: Remove Filter Context to give aggregated count in table

it has to do with :

FILTER(
                     ALL(FactMeetings),

The way ALL is being used here is to remove filters. There's more too it, but there are many sources out there that have explained this. But just play around with ALL using a table and ALL using a Table Column, ALLEXCEPT. Just see what happens and it will begin to click.
