If I have 2 ledger groups and they are 0L and U0 respectively and assign accounting principle IFRS to 0L and US GAAP to U0. What happens if I create a new ledger group called 0LU0 and assign ledgers 0L and U0 to this ledger group? I understand that you are unable to assign an accounting principle to more than one ledger group so would that mean that the principle would be derived automatically?
