Hello there spandy34 ! I figure that you are expecting a measure so here goes.

Hope this works for you:

Lost Time = DATEDIFF ( SELECTEDVALUE ( 'Table'[Actual_Duration_mins] ), SELECTEDVALUE ( 'Table'[Comm_Duration_mins] ), MINUTE )

Hope this answer solves your problem!

Thank you very much

So I have the column below which is a which the format Time. I want to create another column that is a decimal of that so for example if the column says 0.30 I want the new column to display 0.5 as a decimal of an hour.

Can you help with the DAX for that please.

THank you goncalogeraldes

You can use the FORMAT() function:

New column = FORMAT ( Table[Comm_Duration_mins], "General Number" )

What field type does my new column need to be as I get the following response as the new column is set to text?

Just go:

New column = VALUE( FORMAT ( Table[Comm_Duration_mins], "General Number" ) )

I have put this in and get the following:-

this is what I have put in the column

Comm_Duration_Decimal = VALUE(FORMAT ( Procurement_Data_2[Comm_Duration_mins], "General Number" ) )

Try this then:

Comm_Duration_Decimal = VALUE ( FORMAT ( SELECTEDVALUE ( Procurement_Data_2[Comm_Duration_mins] ), "0.00" ) )
