CALCULATETABLE Function error
I am using the following expression to poulate a measure:-
TestMeasure = CALCULATETABLE( 'Table', 'Table'Field <> BLANK() )
Which is returniong the following error: -
The expression refers to multiple columns. Multiple columns cannot be converted to a scalar value.
Isn't the whole point of CALCULATETABLE that it returns a table rather than a scalar value? Im very confused by this, any assistance would be greatly appreciated.
Im hoping to create the table so that I can then select the max value from a column within it.
Is there another way I can approach this?
Thanks

Anonymous thanks for the reply.
I had assumed as much (I'm quite new to PowerBI but I have a strong T-SQL background).
I am simply trying to select the maximum Date (ColA) from Table1 where ColB is not null. Im I going about this the wrong way?
I used you solution in my first itteration but it does not allow for the NULL filter.
Thanks
The problem was that I was trying to stuff a table into a scalar variable.
