How can I get a forecast in Demantra valued by item's unit price not only by quantity?

Hello Everyone.

We have Demantra version 7.3.0 and We would like to have our Demantra's Forecast calculated by item's price, not only by quantity. Sales force in our company not only what to analize forecast in quantities but also valued by item's unit price

According to some documentation, the price for the items can be collected from EBS by running collection for price list first,  and then  running the Workflow:  EBS Price List
Download, to download Price Lists using an import integration profile.

So far it is OK, but when we check the Series in the worksheet's setting,  we can only see the item's unit price in the series: EBS: Price lists but it doesn't value the forecast quantities.  so, it's not enough by collecting prices from ebs in order to have a valued forecast.
