## Need help with showing differences

I want to show the difference between 2012 and 2011 data.  I have the data in the pivottable chart in Qlikview, but I cannot figure out how to show the difference between year.  For example, i sold 10000 of product A in 2011, and 12500 of product A in 2012.  I want another column that shows me the difference of 2500.

Hi

You can do this with the following expressions (modify as required):

• Sum({<Year = {2011}>} Sales)
• Sum({<Year = {2012}>} Sales)
• Sum({<Year = {2012}>} Sales) - Sum({<Year = {2011}>} Sales)

You need a Year field for this to work. If you don't have one, add one in your load script with

Sales,

SalesDate,

Year(SalesDate) As Year,

..

FROM ..;

You might want to post your qvw (or a sample thereof) for more specific assistance.

Hope that helps

Hi,

I should agree with Jonathan. His solution will work perfectly.

But you can also try this expression which is exactly what you have asked.

Count({<Product={'A'}, Year={2012}>} DISTINCT Product) - Count({<Product={'A'}, Year={2011}>} DISTINCT Product)

The above expression gives you the difference of no of Product A sold in 2012 and 2011.

## Re: Need help with showing differences

Hi,

No need of writing any new expressions for this, just use the expressions you already used for 2011 and 2012.

Suppose if your expression name Year 2011 and Year 2011 the the difference of this expression would be

=[Year 2012] - [Year 2011]

Hope this helps you.

Jagan.

## Need help with showing differences

One more question, I want to see the difference between year and a specific company.  So i need to say where year = 2011, which is work, but also where COMPANY = KateAspen.  I need that in the same query, how would i do that.

Hi

Just add it to the set expression like this:

Sum({<Year = {2011}, Company = {'KateAspen'}>} Sales)
