Summing up sales for previous year

Hello -

 

I'm trying to pull into a table on my card the following:

 

Current Year Sales

Previous Year Sales

 

The calculation I'm using for previous year sales in beast mode is 

 

CASE
WHEN YEAR(current_date()) = YEAR(`week_beginning`) - 1
THEN SUM(`sales`)
ELSE 0
END

 

or

 

sum(CASE
WHEN YEAR(current_date()) = YEAR(`week_beginning`) - 1
THEN `sales`
ELSE 0
END)

 

but I'm getting a value of 0 for previous year sales.

 

The data is aggregated weekly data we receive from a partner.

 

Thank you

    I think the likely solution is that on the card itself, you need to specify the date range to include the previous 2 years, like pictured in the attached.

     

    Let me know if that helps.

    I think that you are subtracting 1 from the wrong year field:

     

    try this.

     

    sum(CASE
    WHEN YEAR(current_date())-1 = YEAR(`week_beginning`)
    THEN `sales`
    ELSE 0
    END)

    Moving the 1 to the first instance worked on some level, but only when I pull in a long date range, i.e., 2 years. What I'm trying to do though, is pull sales for any date range, say 1 week or 1 month and compare those sales to the previous year sales during the same time frame. I tried using this query

     

    sum(CASE
    WHEN year(`week_beginning`)-1 = year(`week_beginning`)
    THEN `sales`
    ELSE 0
    END)

     

    Which instead of using current_date() in the first instance, I use week beginning in hopes that whatever week I want to look at for this year, it will bring in previous year sales for the same week. This isn't working either, however.

    Have you looked into the period over period graphs?
