1. What is Outlier group In APO?

Not sure if outlier group exist in APO.....

Outlier: Lets say you have planned your expenses @ 500 $ per
month. However due to festivities you see sudden spike in
your expenses in the month of Oct, Nov and Dec (say by 400
). Your annual forecast was 6000 but due to recent 3 month
activity actual is 7200. These spikes are called outlier.

Smoothing: When you account for these changes over a period
of time (even distribution). In this case it would be 600
per month instead of 500 till Sept and 900 for Oct, Nov & Dec.

2. What is consensus forecast?how its used?what are the FORECAST models involved in?

Consensus forecast refers to a business process, not a
system function. It basically means forecast created with
the mutual agreement of the various business functions,
e.g. supply chain, finance, sales, etc.
As such it is not linked to any statistical forecast models
(I assume you meant that) and you can use any and all
models, it will not create a consensus forecast for you.
You have to take your numbers and discuss and agree about
them with your colleagues of the different departments.
That's what will make your forecast consensus based.
