How to get the difference between more rows?

Hey guys, 

 

i need your help please i hava a huge table with lot of data (many excel files in one folder) and i want the differences between the Sources (excelfiles). 

 

I have found something which is almost good for that what i want in the Quick Measures:

 

Value difference from LIST_211022_MOT_PROG_P2022-01_final.xlsx =
VAR __BASELINE_VALUE =
    CALCULATE(
        SUM('Zusammenfassung'[Value]),
        'Zusammenfassung'[Source.Name]
            IN { "LIST_211022_MOT_PROG_P2022-01_final.xlsx" }
    )
VAR __MEASURE_VALUE = SUM('Zusammenfassung'[Value])
RETURN
    IF(NOT ISBLANK(__MEASURE_VALUE), __MEASURE_VALUE - __BASELINE_VALUE)
 
But the problem here ist that the Source is not dinamic, i have to filter between the differen excel files and need that den differences.
 
Almost like the function in the pivot tabel (show values as difference).
 
Can you help me please?

If you want to follow my suggestion and disply the results in a tablevisual, then place the Sorce Name column in the table along with the following measure. From the visual format options, activate the total and rename it "Difference"

Value =
VAR MeasureValue =
    SUM ( 'Zusammenfassung'[Value] )
VAR T1 =
    ADDCOLUMNS (
        VALUES ( 'Zusammenfassung'[Source.Name] ),
        "@Value", CALCULATE ( SUM ( 'Zusammenfassung'[Value] ) )
    )
VAR DifferenceValue =
    MAXX ( T1, [@Value] ) - MINX ( T1, [@Value] )
RETURN
    IF (
        HASONEVALUE ( 'Zusammenfassung'[Source.Name] ),
        MeasureValue,
        DifferenceValue
    )

If you wish to display the difference in a seperate chart, then place the following measure in the chart ALONE (don't place any column along with it in the same chart)

Value difference =
VAR T1 =
    ADDCOLUMNS (
        VALUES ( 'Zusammenfassung'[Source.Name] ),
        "@Value", CALCULATE ( SUM ( 'Zusammenfassung'[Value] ) )
    )
RETURN
    MAXX ( T1, [@Value] ) - MINX ( T1, [@Value] )

Hi @KimBoehmer 
Please refer to attached sample file with the solution. I've created a new column using power query to get the Source Number for sorting purposes.

Value = 
VAR MeasureValue =
    SUM ( 'Zusammenfassung'[Wert] )
VAR T1 =
    ADDCOLUMNS (
        VALUES ( 'Zusammenfassung'[Source.Name] ),
        "@Date", CALCULATE ( MAX ( 'Zusammenfassung'[Source.Number] ) ),
        "@Value", CALCULATE ( SUM ( 'Zusammenfassung'[Wert] ) )
    )
VAR FirstRecod =
    TOPN ( 1, T1, [@Date], ASC )
VAR LastRecod =
    TOPN ( 1, T1, [@Date] )
VAR DifferenceValue =
    MAXX ( LastRecod, [@Value] ) - MAXX ( FirstRecod, [@Value] )
RETURN
    IF (
        HASONEVALUE ( 'Zusammenfassung'[Source.Name] ),
        MeasureValue,
        DifferenceValue
    )

The error is gone but there is no output 

 

 

Here the example ( the older version is on top, the newest version on the bottom):

KimBoehmer_0-1663784527940.png

 

Normaly the difference between these two should be negative and not positiv.

 

Do you know what i mean?
