MINX of Measure not behaving as expected

[colsen12]

I have a slicer to select a Country, and a table with 3 measures based on this slicer. The three measures are: Average Historical ASP, Average Material Cost, and Margin. I am trying to add a 4th measure which finds the minimum value from all values in the Margin column.

The formula I am currently using is: 

Min Margin = MINX('Historical ASP', [Margin])

I would expect that with all Country values selected, it should show 3.27 as Min Margin for all rows in the above. Where am I going wrong?

hi @colsen12 

Seems on the wrong granularity,  try like:

Min Margin =
MINX(
    SUMMARIZE(
        'Historical ASP', 
        'Historical ASP'[Country], 
        'Historical ASP'[PH7]
    ),
    [Margin]
)

@colsen12 Try:

Min Margin = 
  VAR __Table = SUMMARIZE(ALL('Historical ASP'),[Country],"__Margin",[Margin])
  VAR __Result = MINX(__Table,[__Margin])
RETURN
  __Result

@Greg_Deckler Thanks that works. Was wondering, if I wanted to measure MINX only for selected Country fields from the slicer, where do I add that in?

Try ALLSELECTED instead of ALL.
