Data type & formatting

Hi 

 

I have data in weeks and years

originally in excel it is in 1/2017.. 2/2017... 3/2017 format

In PBI query view i split the columnt to have week and year 

week    year

1          2017

2          2017

3          2017

 

I would like PBI to recognize this as date Data type so I can use it

 

Anyone can help ..

tahnx

Well, if you don't know what ISO is (despite my explanation...), then I guess your week numbering is like the system used in the USA, where the week starts on Sunday, January 1 is week 1 and week 2 starts on the first Sunday after January 1.

 

In that case, you can add a column with formula:

 

= Date.StartOfWeek(Date.AddWeeks(#date([year],1,1),[week]-1))

By the way, your "Creation week" is a number in Power Query with the year in the fraction part (i.e. as decimals).

If you are using ISO week numbering (i.e. Monday is the first day of the week and the first Thursday in a year is in week 1 and each ISO week has 7 days - also around January 1st) then refer to my solution over here.

I am not sure what ISO means. however here are some pictures to get better idea what my issue is

THis is the orginal format

Here is what happens when I change the data type to date. In adition i tried to change the Year column into Date/Year/Yeartransformed.PNG

 

Hope you can understand better.

 

I would like to have the same view as in the first picutre but the data type will be Date

 

Thank you
