Question

Ajusted demand modifed by an odd number

+1

Hello community,

We are in IFS Cloud 24R2 and we would like to upgrade to 25r2 Su9. I have a problem this yhe adjusted demand in forecast demand.

The quantity in “adjusted demand” is changed by a process. I can't figure out why this happens or how to prevent it.

I get the impression that these changes are related to the qualification task.

Thanks for your help.

Hi Sabrina,

I discussed this with colleagues in IFS Product & Tech (IFS R&D) and it looks like Demand Planner Data Cleansing is at work here.

Data Cleansing is a feature of the Demand Planning forecast engine that cleans historical demand data as part of the forecasting process.

This helps to prevent unusual spikes or one-off demand events from distorting the statistical forecast.

The standard Data Cleansing method performs the following tasks:

Calculates the standard deviation of historical demand.
Identifies demand values that are more than three standard deviations from the norm.
Replaces those extreme values with the 3 sigma limit before forecast model calculations are performed.

I hope that this helps!

Richard.

Hi Sabrina,

Apologies, I should have mentioned that! 😀

You control it in the Demand Plan Server / Advanced Server Settings

Filter for Setting = ‘CleansingMethod’

CleansingMethod: 0=No Data Cleansing, 1=Cleanse Data (according to the Standard Derivation Method). The Default Setting = 1.

Try setting the CleansingMethod = 0 and Adjusted Demand periods should never be automatically adjusted.

Good luck,

Richard.
