    Hi Anonymous ,

    1. add a custom column like:

    2. merge queries:

    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"

I think this would be better served by a DAX Measure. And [Nummer] is strictly a dimension of your data.

i did it with dateadd:

Saldo Last Month = CALCULATE(SUM(ER_und_Bilanz[Saldo]),VALUES(ER_und_Bilanz[Nummer]),DATEADD(ER_und_Bilanz[Date],-1,MONTH))

 

But I'm working with a slicer, and then the month before must also be selected that it works. thats why i thought a want to add a column where the data from last month is already inside. so i only have to select one month
