Hi,
I have an excel array formula that I need help in writing the DAX eqivalent.
Columns
Station ID
Start Time
End Time
My formula captures the start time of next start per Station ID.
Next Start Time - Excel Array Formula
{=MIN(IF(A3:A$4983=A2,IF(B3:B$4983>C2,B3:B$4983)))}
I would like to have this calculated in DAX, but cannot figure out equivalent.
Any help would be greatly appreciated.
/tks

Solved! Go to Solution.
@cfstout you can use a measure like this
NextStart =
CALCULATE (
MIN ( 'tbl'[Start Time] ),
'tbl'[Start Time] > MAX ( 'tbl'[Start Time] ),
ALLEXCEPT ( 'tbl', 'tbl'[Station ID] )
)
Hi, thanks for the response.
I am unable to get this to work... would you mind attaching the .pbix file so I can see how you created the VAR?

Thanks so much for your help. Works great!
Hi,
This DAX should do what you want:
The basic logic is to remove filters with ALL and keep the relevant filters with variables. You might need to add SiteID as an variable.
I hope this post helps to solve your issue and if it does consider accepting it as a solution and giving the post a thumbs up!
Proud to be a Super User!
