Changes Between Reports - Complexity Management

Hi Anonymous ,

Will attach Pbix in  a couple.  The crux was selecting the second month, and creating new table from the merge, and using anti.  This is all in Power Query so should be fully auto.
Let me know if you have any questions.

If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos are nice too.

let
    Source = Table.NestedJoin(September, {"Emp"}, August, {"Emp"}, "August", JoinKind.RightAnti),
    #"Expanded August" = Table.ExpandTableColumn(Source, "August", {"Emp", "ID"}, {"August.Emp", "August.ID"}),
    #"Removed Columns" = Table.RemoveColumns(#"Expanded August",{"Emp", "ID"})
in
    #"Removed Columns"
