Combine Tables with Missing Rows

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"
