Direct Query Calculate LastDate issue

[shippen70]

I am creating a visual for a Direct Query.  I need to return the LastDate from my Date Dimension table (Rolling Calendar) and pass that into my CALCULATE Function to sum the TotalDrawers for that date.  I keep getting a locking error.  When I check it in DAXStudio it indicated there is an issue with LASTDATE.  Seems that this has to do with the LASTDATE being used in a CALCULATE function on a Direct Query.  Any thoughts on how to resolve the issue?

WTDDrawers =

VAR SelectDate =

LASTDATE( 'Rolling Calendar'[Calendar Date] )

VAR DayNumberOfWeek =

WEEKDAY ( LASTDATE ( 'Rolling Calendar'[Calendar Date] ), 1 )

//VAR TestFirstDate = DATEADD ( SelectDate, ( -1 * DayNumberOfWeek ) + 1, DAY )

RETURN

CALCULATE (

SUM ( _AE1WeekComp[TotalDrawers] ),

DATESBETWEEN (

'Rolling Calendar'[Calendar Date],

DATEADD ( SelectDate, ( -1 * DayNumberOfWeek ), DAY ),

SelectDate

)

)

@shippen70 , Try like

WTDDrawers =
VAR SelectDate =
maxx(allselected('Rolling Calendar'), 'Rolling Calendar'[Calendar Date] )
VAR DayNumberOfWeek =
WEEKDAY ( SelectDate, 1 )
//VAR TestFirstDate = DATEADD ( SelectDate, ( -1 * DayNumberOfWeek ) + 1, DAY )
RETURN
CALCULATE (
SUM ( _AE1WeekComp[TotalDrawers] ),
DATESBETWEEN (
'Rolling Calendar'[Calendar Date],
DATEADD ( SelectDate, ( -1 * DayNumberOfWeek ), DAY ),
SelectDate
)
)

I did no check formula logic

Hi @shippen70 

Try MAX( 'Rolling Calendar'[Calendar Date] )

I tried using MAX but then I get the error that is needs a Column Reference.

Hi @shippen70 

Is this happening when using MAX( _ ) on its own or only as part of your synatx?
