YoY Variance: Trouble Excluding When Most Recent Week's Data is Absent

I've built a YoY variance chart for sell-out sales but problem is I'm using CURDATE for the most recent week and it's showing -100% until I upload the most recent sales data.

 

I've proposed the below but it's coming up with an error message. Any help is appreciated!

 

(CASE when (`Sales Week` like '%2018%' then `week_number`)=(`Sales Week` like '%2017%' then `week_number`) then

              SUM(CASE WHEN TRIM(YEAR(`Date`))=YEAR(CURDATE()) then (`Sell_out_value`) else 0

              End)

              /

             SUM(CASE WHEN TRIM(YEAR(`Date`))=Year(ADDDATE(CURDATE(), interval -1 year)) then (`Sell_out_value`) else 0

             End)

             -1

else 0

end)

  • Your exterior CASE WHEN has some syntax errors, but instead of trying to fix those, you might could try this:

    CASE WHEN `Sales Week` LIKE '%2018%' AND `Sell_out_value` IS NOT NULL THEN 
    SUM(CASE WHEN TRIM(YEAR(`Date`))=YEAR(CURDATE()) then (`Sell_out_value`) else 0

    End)

    /

    SUM(CASE WHEN TRIM(YEAR(`Date`))=Year(ADDDATE(CURDATE(), interval -1 year)) then (`Sell_out_value`) else 0

    End)

    -1

    else 0

    end

    Hope that helps,
