# 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?
