Did you notice that accounts defined outside the balance sheet hierarchy has started to roll forward since Nov close ? That’s because of the previously communicated 20.11 upgrade feature that extends account scope of translation and consolidation. Since you have certain customization needs and you wish to not have these accounts to roll forward outside the balance sheet hierarchy, you can set up a new variable called “ExtendAccountScope” and set the value to “False”. You may need to reconsolidate if you haven’t locked prior periods as needed.
