Hello,
I was reading the SAP documentation regarding the Outlier correction with the median method and this question came in my mind. There was a formula for expected value:

and there was also a formula for the tolerance lane: Sigma * Expected value. So does this mean that
1. if a historical value is outside the range: ex-post forecast ± Sigma * Expected value, where ex-post forecast is the Expected value because ex-post forecast is calculated with median method, then it corrects the value
or does it mean that
2. if a historical value is outside the range: historical value ± Sigma * Expected value then it corrects the value?
or is it something else?
