What-if parameters

At the retail company i work, the sales men are giving the customers discounts. At the end of  the year, the sum of sales after discount =100M and the total dicounts amount=45M. 

i want to make a what if parameter to the discounts in which i make it dynamic to show that :


if we decreased  the discount amount by 10% the sales would have increased by so and so ..


how can I achieve that ?

Hi Moeaqrl,


This is fairly easy to achieve in PowerBI desktop.

Go to Modelling -> What if -> New parameter


Change to below values, for a % change






This then creates a discount field which can be used in a slider for the data entry, and referenced in measures:




New discount % = PercentDiscount[PercentDiscount Value]
Sum of Sales without Discount = sum('what if'[Sales]) + sum('what if'[Discount])
New Discount, $ = [Sum of Sales without Discount] * PercentDiscount[PercentDiscount Value]
New Sales Amt = [Sum of Sales without Discount]-[New Discount, $]
Difference = [New Sales Amt]-sum('what if'[Sales])
Resulting table - is dynamic when the value in the slider is changed
