Duplicate rows with new values

Hi,

 

I have a table like that :  Customer|Date|amount

 

I need to duplicate each row 12 times each time with the next month 

example:

original row

customer   |   Date    | amount

1                | 1/1/17   | 100

 

I need it to be like : 

customer   |   Date    | amount

1                | 1/1/17   | 100

1                | 1/2/17   | 100

1                | 1/3/17   | 100

1                | 1/4/17   | 100

 

Is it possible to do it with power bi?

 

Thanks,

Re: Duplicate rows with new values

Hi @Drors

 

Try this solution

 

Go to Modelling Tab>>> New Table

 

New Table =
GENERATE (
    TableName,
    VAR mymonth = MONTH ( TableName[Date] ) RETURN GENERATESERIES ( 0, 11, 1 )
)

Now Add this CALCULATED COLUMN to your NEW TABLE

 

New date =
DATE ( YEAR ( 'New Table'[Date] ), MONTH ( 'New Table'[Date] ) + 'New Table'[Value], DAY ( 'New Table'[Date] ) )

Re: Duplicate rows with new values

This would be my Power Query solution:

 

let
    Source = TableName,
    DateList = Table.TransformColumns(Source,{{"Date", (startdate) => List.Transform({0..11}, each Date.AddMonths(startdate,_)), type {date}}}),
    #"Expanded Date" = Table.ExpandListColumn(DateList, "Date")
in
    #"Expanded Date"
Specializing in Power Query Formula Language (M)
