Last values from measures in a table

Hi,
I need to calculate last values from measures in a table.
The table below shows last 2 dates from 1 year selection.

The Grade and Freq measures and based on MEAN ans STDEV.S calculations
I need measures to calculate
Max Grade to equal a reslut of "B"
Max Freq of the Max Grade to equal a reslut of "High" (if there was a high and low result for Grade "B" the Freq = "Low")

I also need a measure to concatenate the Analyte names for every Grade = Max Grade for the entire selected date range

4/8/2020 has highest grade "C" so Concatenate = Cu, Se, Zn


I can cant filter to last date as this would change the calculations for Grade and Freq as they are dynamically based on the entire selected date range. 

Last 2 dates

First 2 dates

Calulations:

Cont Mean = CALCULATE(DIVIDE([Cont Total],[Cont Count]))

Cont Total = [Historical Total]+[Samples Total]

Cont Count = [Historical Count]+[Samples Count]
 
Cont Std Dev = CALCULATE(STDEV.S('Labware'[Calculated Value]),DATESBETWEEN(Labware[Calendar Date],[Historical Date],[First Sample Date]),ALL(Labware[LIMS Text ID]))
 
Grade = Switch(
True(),
'Labware'[CtA]<3.5,"A",
'Labware'[CtB]<3.5,"B",
'Labware'[CtC]<3.5,"C",
'Labware'[CtD]<3.5,"D",
"E")
 
CtA = CALCULATE(IF([V]>0,[Cp]+(([V]-(MAX('Labware'[A Grade])-1.78*[Cont Std Dev]))/[Cont Std Dev]),IF([V]>MAX('Labware'[A Grade]),7,0)))
 
CtB = CALCULATE(IF([V]>0,[Cp]+(([V]-(MAX('Labware'[B Grade])-1.78*[Cont Std Dev]))/[Cont Std Dev]),IF([V]>MAX('Labware'[B Grade]),7,0)))
 
CtC = CALCULATE(IF([V]>0,[Cp]+(([V]-(MAX('Labware'[C Grade])-1.78*[Cont Std Dev]))/[Cont Std Dev]),IF([V]>MAX('Labware'[C Grade]),7,0)))
 
CtD = CALCULATE(IF([V]>0,[Cp]+(([V]-(MAX('Labware'[D Grade])-1.78*[Cont Std Dev]))/[Cont Std Dev]),IF([V]>MAX('Labware'[D Grade]),7,0)))
 
Thanks Rodney

Hi,

I have made some progrerss with concatenate. Shows correct result in table but as a card result is Blank

 

zenton_0-1657171480648.png

Limiting Contam Test =

VAR VisualValues =
CALCULATETABLE (
ADDCOLUMNS (
SUMMARIZE (
Labware,
RMD_tlkp_AnolyteMasterList[strColumnLabel],
Labware[Calendar Date],
Labware[LIMS Text ID]
),
"@Grade", Labware[Grade]
),
ALLSELECTED ()
)
VAR MAXGRADE =
MAXX ( VisualValues, [@Grade] )
VAR GRADE =
SWITCH (
TRUE (),
'Labware'[CtA] < 3.5, "A",
'Labware'[CtB] < 3.5, "B",
'Labware'[CtC] < 3.5, "C",
'Labware'[CtD] < 3.5, "D",
"E"
)
RETURN
CALCULATE (
CONCATENATEX (
RMD_tlkp_AnolyteMasterList,
RMD_tlkp_AnolyteMasterList[strLegendName],
", "
),
ALLSELECTED (),
FILTER ( Labware, GRADE = MAXGRADE )
)

Hi @zenton ,

You can create a measure as below and put this new measure onto the card visual:

New Measure =
MAXX (
    GROUPBY (
        Labware,
        Labware[Date],
        Labware[LIMS Text ID],
        Labware[Analyte],
        Labware[Freq],
        Labware[Grade]
    ),
    [Limiting Contam Test]
)

If the above one can't help you get the desired result, please provide some sample data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file. You can refer the following link to upload the file to the community. Thank you.

Hi @v-yiruan-msft

Calculation won't accept Labware[Grade] or Labware[Freq] because they are Measures.
I can try to make simplified pbix file but not easy to do. 80 Tables, 50 relationships and 320 Measures

Thanks Rodney

Hi @v-yiruan-msft 

I have made a simplififed version of PBIX with 2 sample reports
