## DAX Weekly YOY

Hello everyone,

I need some help in DAX and I would really really appreciate any inputs.

This is my Quotes_Year_Wk table

Year_Week   Quotes

2019-25       13,582

2019-26       13,112

2019-27       12,908

2020-25       20,927

2020-26       21,126

2020-27       26,064

I want to calculate weekly YOY for quotes by using Year_Week column

For example, I want to know the YOY change in week 25.

From the table above, I want to get

2019-25       13,582

2020-25       20,927

Wk_YOY = 20,927/13,582-1

I honestly have a hard time figuring out the correct DAX to get the vakue I needed :'(

Thank you so much!

@Newbie_2020 , Split year and week .

year = left([Year_Week ],4)

Week  = right([Year_Week ],2)

better move week year to a new new table and create these columns there. Join on week year with the original table

example

YTD Week = CALCULATE(sum('Table'[Quotes]), FILTER(ALL('Date'),'Date'[Week]<=max('Date'[Week]) && 'Date'[Year]= max('Date'[Year])))
LYD Week = CALCULATE(sum('Table'[Quotes]), FILTER(ALL('Date'),'Date'[Week ]=max('Date'[Week]) && 'Date'[Year]= max('Date'[Year])-1 ))

'Date' is new table you have week year

very similar approach
