Combine Tables with Missing Rows

[Anonymous]

I have two tables as shown below:

Partner

Code	Partner	Backlog
1111	One	500
2222	Two	100
3333	Three	300

Project History

Partner Code	Amount	Project
1111	300	Proj1
1111	100	Proj2
2222	400	Proj3

When I combine the tables I get the below result:

Partner	Code	Amount
One	1111	400
Two	2222	400

However, what I'd like to see is the below:

Partner	Code	Amount
One	1111	400
Two	2222	400
Three	3333	0

Is there anyway to accomplish the above without actually merging the queries? The two tables are already large and would like to avoid that if possible.

Hi @Anonymous,

I try to reproduce your scenario, and get expected result. Please follow the steps below.

1. In query Editor, please click "Merge query as new" (highlighted in yellow). Merge the two tables by Code shown in picture2.

2. You will get the table below(Picture3), then remove the Backlog, Parter Code and Project fields.

3. Then click "Group by" as the picture4 shown.

4. Click "Apply" on Home page. You will get expected result shown in Picture5, and review my query statement.

Picture5

let
    Source = Table.NestedJoin(Partner,{"Code"},#"Project History",{"Partner Code"},"Project History",JoinKind.LeftOuter),
    #"Expanded Project History" = Table.ExpandTableColumn(Source, "Project History", {"Partner Code", "Amount", "Project"}, {"Project History.Partner Code", "Project History.Amount", "Project History.Project"}),
    #"Removed Columns" = Table.RemoveColumns(#"Expanded Project History",{"Backlog", "Project History.Partner Code", "Project History.Project"}),
    #"Grouped Rows" = Table.Group(#"Removed Columns", {"Code", "Partner"}, {{"Amount", each List.Sum([Project History.Amount]), type number}})
in
    #"Grouped Rows"

If you are merging the two queries you should be able to control the behavior in question with the Join Kind option:
