Weekyear ISO comparison

[noliverte]

Hello,

I have 1  table  with details of the sessions each days (2015-->2020) Named Freq-web-all

I have a calendar calculated field Named Calendrier

I linked these 2 tables in the model view on date (date with calendar date)

I would like to show sessions evolution (%) between week w-1 et week w-2 based on today's date

(today is wednesday 09/12/2020 , week 50... I would like to display the sum of my sessions week 49 and 48)

What I tried :

• insert weekyear number in my sessions table but I didn't succeed. (with iso version)
• sum sessions with a filter based on the weekyear ISO number

Could you help to build my measure based on W-1 ?

A response would be greatly appreciated

Have a nice day

Hi @noliverte ,

You can create a yearweek number like this

calendar =
ADDCOLUMNS (
    CALENDAR ( DATE ( 2015, 1, 1 ), TODAY () ),
    "yearweek",
        YEAR ( [Date] ) & "-"
            & WEEKNUM ( [Date] ),
    "sort",
        YEAR ( [Date] ) * 100
            + WEEKNUM ( [Date] )
)

For filtering the value you want, you could create a relationship between the calendar table and the main table.

The sort column is created to sort the yearweek colulmn.

After the above steps are completed, you can create a view to filter.

You can check more details from here.
