Create a table based on a date

[Slaper]

I have the following problem. 

Create a measure :

NewTableLastDate =
var
Find =SWITCH(
WEEKDAY(TODAY(),2)
,1,today()-4
,7,today()-3
,6,today()-2
,today()-1
)
Var compare = if(
Find > max('tbl'[Dates])
,max('tbl'[Dates])
,Find
)
return compare

then a create a table:

TodayDat = filter('tbl','tbl'[Dates]=[NewTableLastDate])

But the filter is not working like this. if I do it like this, then it works.

NewTableLastDate =

SWITCH(

    WEEKDAY(TODAY(),2)

    ,1,today()-4

    ,7,today()-3

    ,6,today()-2

    ,today()-1

)

What am I doing wrong?

Hi @Slaper ,

What Greg_Deckler said makes sense.

In DAX, measures are designed to aggregate data and return a single value.

The problem arises from trying to compare the column directly to the measure in the function. You should use calculated columns to achieve the desired results.

Replace NewTableLastDate with a calculated column so that you can use this column directly in filter expressions.

I would be grateful if you could provide me with sample data, please remove any sensitive data in advance.

If you have any further questions please feel free to contact me.

I have found the solution,

TodayDat =
VAR Find =SWITCH(
WEEKDAY(NOW(),2)
,1,today()-4
,7,today()-3
,6,today()-2
,today()-1
)
VAR Compare=if(
Find > max('tbl'[Dates])
,max('tbl'[Dates])
,Find
)
RETURN
CALCULATETABLE (
FILTER ( tbl, 'tbl'[Dates]=Compare))

@Slaper You can't use measures like that. Measures are for use at the reporting level.
