DATEDIFF as DAX Measure
Hello all,
I am trying to create a measure that calculates the difference between 2 time columns (hh:mm:ss format) and gives a result as a decimal. DATEDIFF works as a calculated column, but I cannot figure out how to translate to a DAX Measure. My report is saying there is too much space being taken up, so I want to change these columns to measures.
Please help!
You could try either of these measure expressions
TimeDiff = SUMX(Table, Table[TimeColumn1] - Table[TimeColumn2]
or
TimeDiff = SUMX(Table, DATEDIFF(Table[TimeColumn1], Table[TimeColumn2], MINUTE))If you make a table visual with both time columns, you should see the difference when you add the measure. Or you could use the aggregate, maybe switching to AVERAGEX, MAXX, etc. depending on what you are looking for.
Also, there are probably more impactful ways to reduce the file size of your model.
If this works for you, please mark it as the solution. Kudos are appreciated too. Please let me know if not.
Regards,
Pat

[Date1] -[Date2] will give in that format.
If you get in in second, minute or hour refer this for the duration of your choice
Anonymous , in Measure you need to
measure = max([Date1]) -min([Date2])
Take care row context while using. refer this blog how summarize and valuea has been used
