Combining two pivoted tables ("pivoted" by groupby in tables)

[JHopkins]

Hello,

I have been beating my head agains a wall for a week and need the help others.  I am able to pivot two sets of data into two separate report screens.  I am also able to "pivot" the two sets of data with GROUPBY into two separate tables.  I cannot for the life of me figure out how to combine the two tables into one.

Made Table:

Dimension	Date	Made
1	2020-11-03	1000
2	2020-11-03	1100
3	2020-11-03	900
4	2020-11-03	1200
5	2020-11-03	1300
6	2020-11-03	100
7	2020-11-03	500
8	2020-11-03	600
9	2020-11-03	500

Sampled Table:

Dimension	Date	Sampled
1	2020-11-03	50
2	2020-11-03	30
3	2020-11-03	50
4	2020-11-03	50
5	2020-11-03	30
6	2020-11-03	30
7	2020-11-03	10
8	2020-11-03	50
9	2020-11-03	20

I've tried joins,different summarizes, and have gotten very lost trying to understand the more detailed use of filters etc....My goal is to be able to display all of the data in one table like this:

Dimension	Date	Made	Sampled
1	2020-11-03	1000	50
2	2020-11-03	1100	30
3	2020-11-03	900	50
4	2020-11-03	1200	50
5	2020-11-03	1300	30
6	2020-11-03	100	30
7	2020-11-03	500	10
8	2020-11-03	600	50
9	2020-11-03	500	20

There are probably better ways when I bring the data in or when I create the tables themselves...I am hoping some more experienced minds can enlighten me.

Thanks!

Hi @JHopkins ,

There are two ways, one is to merge them in Power Query Editor.

Another way is to create a calculate column in Made table.

Sample column = 
CALCULATE(
    SUM('Sampled Table'[Sampled]),
    FILTER(
        'Sampled Table',
        'Sampled Table'[Dimension]='Made Table'[Dimension]
        &&'Sampled Table'[Date]='Made Table'[Date]))

If it doesn’t meet your requirement, could you please show the exact expected result based on the table that you have shared?

This should work:

let
    Source = Table.NestedJoin(#"Made Table", {"Dimension"}, #"Sampled Table", {"Dimension"}, "Sampled Table", JoinKind.Inner),
    #"Expanded Sampled Table" = Table.ExpandTableColumn(Source, "Sampled Table", {"Sampled"}, {"Sampled"})
in
    #"Expanded Sampled Table"
