Count IDs which Increased/Decreased

[ET1995]

Hi all,

Please please help me out with this. So this is my table (made using the power BI visual matrix). The rows are IDs and the columns are Dates, usually a week apart (but not always). The values are sum of the quantity of each ID (PDQ). I want to count the number of IDs, which have at leaste ONE change across these 8 weeks.

SKU	1/6/2021	1/13/2021	1/20/2021	1/27/2021	2/3/2021	2/10/2021	2/17/2021	2/24/2021
A	1	1	1	1	1	1	1	1
B	2	2	3	3	3	3	1	1
C	3	3	4	4	5	5	5	4
D	3	3	3	3	3	3	3	2
E	1	1	1	1	1	1	1	1
F	3	3	3	3	3	3	3	3
G	0	1	1	1	1	1	1	1
H	4	4	5	5	5	5	5	5
I	3	3	3	3	3	3	3	3
J	2	2	2	2	2	2	2	2
K	1	1	1	1	1	0	0	0
L	4	4	4	4	4	4	4	4
M	1	1	1	1	1	1	1	1

I have a measure which calculates the previous week's PDQ:

lastpdq = 
var latestDate = MAX(Append1[MinDate])
VAR prevDate = CALCULATE(MAX(Append1[MinDate]),Append1[MinDate]<latestDate,ALLSELECTED(Append1[MinDate]))
RETURN
CALCULATE(
SUM(Append1[PDQ]),
Append1[MinDate]=prevDate, ALLSELECTED(Append1[MinDate]))

Using this I calculated the Variance between previous and current week. I used this to apply condiitional formatting as well and it works perfectly fine.

I tried using this (and much more) to get the count, but nothing is working:

Count = CALCULATE(
    COUNTROWS( SUMMARIZE( Append1, Append1[SELL_ID] )),
    FILTER( SUMMARIZE( Append1,Append1[SELL_ID] ),[Variance]>0||[Variance]<0))

Hi @ET1995 ,

Use something like:

Count IDs changed at least once =
VAR a =
    ADDCOLUMNS (
        SUMMARIZE ( 'Table', 'Table'[SKU] ),
        "VALUE",
            COUNTROWS (
                DISTINCT (
                    SELECTCOLUMNS (
                        FILTER (
                            SUMMARIZE (
                                'Table',
                                'Table'[SKU],
                                'Table'[Date],
                                "PDQ", COUNT ( 'Table'[SKU] )
                            ),
                            'Table'[SKU] = EARLIER ( 'Table'[SKU] )
                        ),
                        "VAUE1", [PDQ]
                    )
                )
            )
    )
RETURN
    COUNTX ( FILTER ( a, [VALUE] >= 2 ), 'Table'[SKU] )
