Duplicate rows with new values

[Drors]

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,

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] ) )

wow thank you it works!

Do you have any idea how to do it with a regular table and not calculated one, I think it will make my work difficault later..

and again, Thank you very much, I work on it all day

Hi @Drors

I will look into Power Query solution

@MarcelBeugcould you help?

[MarcelBeug]

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"

Hi @MarcelBeug , superb solution.

Is there a chance to change number of new rows dynamicly based on value from column, differently for every row? So the same rows needs to be duplicated 2 and some 12 times depending what value is in columnt QTY in row that is duplicated. Can I ask for an example in m-language?

2nd question is about changing values in 2 kolumns for each duplicated row. How to change date adding 1 month (as in the example) and in the same time add 1 day for date_2. 

Thank you in advance
