How to summarize /group by/ count measure values

[Tokkerashid]

Hi all,

I have trouble with grouping measure values. I have table events with columns: Product,  measure Price1 (p1) and then created measure Price2 (p2) from p1, and then Differece between these two prices (Diff), also a measure:

Product	p1 (measure)	p2           (measure)	Diff          (p1-p2)
a1	5,525	5,515	0,010
b2	5,535	5,515	0,020
b4	5,525	5,505	0,020
b6	5,520	5,510	0,010
c3	5,520	5,500	0,020
c5	5,525	5,520	0,005
a5	5,530	5,510	0,020
d2	5,505	5,500	0,005
d4	5,525	5,520	0,005

Now I want to group (count) these differences in this way, Value 0,005 is shown 3 times in table, 0,010 is shown 2 times, etc.:

Diff	Total
0,005	3
0,010	2
0,020	4

but it doesn't allow me to group measure valus.

(The CALCULATE  function cannot be used in an expression argument for the GROUPBY() function.)

Any ideas how to do this?

Thanks!

I resolved this issue in a way that I created new table from existing one with a Diff as a column. And then regular DISTINCTCOUNT works.

hi @Tokkerashid 

following your description, you may try to create a measure like this:

Measure = 
VAR _table1 = 
ADDCOLUMNS(
    SUMMRIZE(
        Products,
        Products[Product],
        Products[P1]
    ),
    "p2", [p2]
)
VAR _table2 = 
ADDCOLUMNS(
    _table1,
    "Diff",
    Products[p1]-[p2]
)
VAR _diff = SELECTEDVALUE(SegmentTable[Diff])
RETURN
COUNTROWS(FILTER(_table2), [Diff]= _diff )

The measure is supposed to plot a table visual with the SegmentTable[Diff] column. The Products table and SegmentTable are unrelated.

if case of issue, please consider providing some sample data.

Hi @FreemanZ ,

Unfortunatelly it is not working. Also p1 is a measure, and it is all one same table (Events).
it is not allow me to add in selectedvalue a measure

Have a look at the dynamic segmentation DAX pattern.
