Thanks for your reply @Jan Spurlin.

As you said I haven't migrated to advanced risk this is the form in classic risk only.
if you can see the form I understand that Calculate ALE comes with formula i.e Calculated ALE = Residual ALE + ((Inherent ALE - Residual ALE) * (Calculated Risk Factor / 100)).

but calculated score is populating based on what I am not getting that's where I pointed out my question.

anyhow will look the video that you have share here.
