    3. expand and rename [Saldo] column:

        #"Added Custom" = Table.AddColumn(#"Umbenannte Spalten", "Custom", each Date.AddMonths([Date],-1)),
    #"Merged Queries" = Table.NestedJoin(#"Added Custom", {"Nummer", "Custom"}, #"Added Custom", {"Nummer", "Date"}, "Sorted Rows", JoinKind.LeftOuter),
    #"Expanded Sorted Rows" = Table.ExpandTableColumn(#"Merged Queries", "Sorted Rows", {"Saldo"}, {"Saldo.1"}),
    #"Removed Columns" = Table.RemoveColumns(#"Expanded Sorted Rows",{"Custom"}),
    #"Renamed Columns" = Table.RenameColumns(#"Removed Columns",{{"Saldo.1", "saldo previous month"}})
in
    #"Renamed Columns"
