Filtering and comparing two month year

[Anonymous]

What I want to do here is this, I have 3 years worth of data and what to compare costs in any given month.

How do I get create a calculated column that will be the difference of Cost Per Kg (in the right) - Cost Per Kg (in the left)

So in the example below, I would want have a column there that would be called Cost Per Kg (difference)

Row 1 will then be 15.66-15.74

Could you please help me stalwar1‌ /swuehl‌?

Thanks.

May be using Before function

CostPerKgExpression - Before(CostPerKgExpression)

Missing Manual - Before() and After()

Thanks for the response. How do I do generate the calculated column in the pivot table?

[sunny_talwar]

Not sure I understand your question?

I was hoping to create a new column in the pivot like below. Thanks.

Just add a new measure like this

CostPerKgExpression - Before(CostPerKgExpression)

Make sure to replace the CostPerKgExpression above with the expression you have for CostPerKg..

Does this make sense?

Cost Per Kg is actually Cost/Weight.

When I added measure of Cost Per Kg Delta with Expression: ceil( Sum([Total Amount])/Sum([Actual Weight]),0.01)-Before(ceil( Sum([Total Amount])/Sum([Actual Weight]),0.01))

The other month would not show up, this is how it looked like

You still have 2017-02 selected for your chart right?
