Distinct average by two categories

[Anonymous]

Hello. (sorry for the earlier incomplete post). I am new to power BI. I would like a measure to do a Distinct Average of a column using two (or more) categories for grouping.

ID         DATE                Type       Data1    Data2  Data3...etc.

1          01/01/2020         A            3            8

1          01/01/2020         B            5            2

1          01/01/2020         B            5            4

1          01/01/2020         B            5            3

1          01/01/2020         C            7            1

1          01/01/2020         C            7            2

2          01/01/2020         C            7            2

2          01/01/2020         C            7            1

etc...

I would like the Distinct AVG_ID_DATE measure to give: average for Data 1 (ID/Date/Type):

ID        DATE                AVG_ID_DATE

1          01/01/2020       5  (3+5+7)/3 

Thanks!

@Anonymous I suggest transforming such a 2-dimensional into a 1-dimensional table in the first place, so that a versatile measure can be authored instead of specific Data1, Data2, ...

Measure = AVERAGEX ( DISTINCT ( DS ), DS[Value] )

That probably would simplify things (a simpler table). Thanks!

@Anonymous ,

Try like

Averagex(union(distinct(Table2[Value]),distinct(Table2[Value])),[Value])

Can you share sample data and sample output in table format?

[Anonymous]

Sorry. See edited post above...I tried to clarify why I need distinct average...

[amitchandak]

@Anonymous , Try as a new measure

averageX(values(Table[Type]), max(Table[Data1]))

or
averageX(summarize(Table,Table[DATE],Table[Type],"_1", max(Table[Data1])),[_1])

I tried the 2nd suggestion, it worked. Thanks!

To add a 3rd group_by category, just add it to the summarize table?

averageX(summarize(Table, Table[ID], Table[DATE],Table[Type],"_1", max(Table[Data1])),[_1])
