Hi Anonymous

please try

NewMeasure =
MAXX (
TOPN (
1,
FILTER (
ADDCOLUMNS (
FILTER ( ALLSELECTED ( 'Table'[Date] ), 'Table'[Date] <= MAX ( 'Table'[Date] ) ),
"@Value",
VAR CurrentDate = 'Table'[Date]
RETURN
CALCULATE ( [Measure], 'Table'[Date] = CurrentDate )
),
[@Value] <> BLANK ()
),
'Table'[Date]
),
[@Value]
)

Hello tamerj1 , Thank you for the answer ,However the measure still shows the same results as what I had before ( for your info I replaced Mesure with the max of the total number I had in the column)

Measure = MAXX (
TOPN (
1,
FILTER (
ADDCOLUMNS (
FILTER ( ALLSELECTED ( 'kpi TotalErrorHistory'[Date]), 'kpi TotalErrorHistory'[Date]<= MAX ( 'kpi TotalErrorHistory'[Date] ) ),
"@Value",
VAR CurrentDate = 'kpi TotalErrorHistory'[Date]
RETURN
CALCULATE ( [Measure 2], 'kpi TotalErrorHistory'[Date] = CurrentDate )
),
[@Value] <> BLANK ()
),
'kpi TotalErrorHistory'[Date]
),
[@Value]
)

Please try

Measure2 =
MAXX (
TOPN (
1,
FILTER (
ALLSELECTED ( 'kpi TotalErrorHistory' ),
'kpi TotalErrorHistory'[Date] <= MAX ( 'kpi TotalErrorHistory'[Date] )
),
'kpi TotalErrorHistory'[Date]
),
'kpi TotalErrorHistory'[TotalNumber]
)

tamerj1 Thank you for the suggestion, but this formula replaces the existing totals by max :

This dhould work. You csn replace the outer MAXX with SUMX to sum the rows at total level

Measure1 =
VAR SelectedTable =
ALLSELECTED ( 'kpi TotalErrorHistory' )
VAR CurrentDate =
CALCULATE (
MAX ( 'kpi TotalErrorHistory'[Date] ),
ALL ( 'kpi TotalErrorHistory'[KPIDescription] )
)
RETURN
MAXX (
VALUES ( 'kpi TotalErrorHistory'[KPIDescription] ),
MAXX (
TOPN (
1,
FILTER (
SelectedTable,
VAR KPIDesc = 'kpi TotalErrorHistory'[KPIDescription]
RETURN
'kpi TotalErrorHistory'[Date] <= CurrentDate
&& 'kpi TotalErrorHistory'[KPIDescription] = KPIDesc
),
'kpi TotalErrorHistory'[Date]
),
'kpi TotalErrorHistory'[TotalNumber]
)
)

Would you please place tge following measure in the matrix values and let me know what result do you get?

CALCULATE (
MAX ( 'kpi TotalErrorHistory'[Date] ),
ALL ( 'kpi TotalErrorHistory'[KPIDescription] )
)

tamerj1 This measure shows the date next to the values that are not empty

Apologies for the late response. I got engaged with something else.

This has to be a dimension table. Create a new calculated table

Dates = ALLNOBLANKROW ( 'kpi TotalErrorHistory'[Date] )

create the relationship between the two tables. Place the new dimension date column in the columns of the matrix instead of tge original one. Tyen try the following measure in the values. Remember you can change the MAXX to SUMX based on your requirement.

Measure1 =
VAR SelectedTable =
ALLSELECTED ( 'kpi TotalErrorHistory' )
VAR CurrentDate =
MAX ( 'Dates'[Date] )
RETURN
MAXX (
VALUES ( 'kpi TotalErrorHistory'[KPIDescription] ),
SUMX (
TOPN (
1,
FILTER (
SelectedTable,
VAR KPIDesc = 'kpi TotalErrorHistory'[KPIDescription]
RETURN
'kpi TotalErrorHistory'[Date] <= CurrentDate
&& 'kpi TotalErrorHistory'[KPIDescription] = KPIDesc
),
'kpi TotalErrorHistory'[Date]
),
'kpi TotalErrorHistory'[TotalNumber]
)
)

Thanks @tamerj1 for the answer. It unfortnathly didn't show the expected result .

I finally created Date.WeekOfYear column and the totals were grouped accordinaly , so no emty values were left
