I need the date of a blank count

[Julux12]

Hello everyone! I hope you are well, i have the following problem with a data of date (in text format or date format) and the type of work, so, the date I need is the one that has the minimum value, that is, the one where no count was found (means that there was no type "S" work on that date), as shown in the following image

to better test this I made a test table like this

Date                 Type of work

3/01/2023	M
3/01/2023	M
3/01/2023	S
3/01/2023	S
2/01/2023	M
2/01/2023	M
2/01/2023	M
1/01/2023	M
1/01/2023	S

and i put my matrix with the data

and i tried the following meausure for this but obviously it didn't work for me

date for min work S =

var _summarized = SUMMARIZE(Table_1, Table_1[Date], "var1",

CALCULATE(COUNT(Table_1[Type of work]),FILTER(Table_1, Table_1[Type of work] = "S"))

)

return MINX(

    FILTER(

        _summarized,

        [var1] = MINX(_summarized,[var1])

    ),

    [Date]

)

please, can you help me ?

try this @Julux12 

Measure = 
VAR base = tbl
VAR s =
    SUMMARIZE ( FILTER ( base, [Column2] = "S" ), [Column1] )
VAR m =
    SUMMARIZE ( FILTER ( base, [Column2] = "M" ), [Column1] )
VAR anti =
    TOPN ( 1, EXCEPT ( m, s ), [Column1], ASC )
RETURN
    MAXX ( anti, [Column1] )
