We have three ledgers, A, B an C.
Each ledger have their own legal entity values.
A Ledger > LE A1, A2, A3

Each of the above LE is configured as an Intercompany Organization.

A user has been provided with the role Intercompany Accountant and have the Intercompany Organization access to A1, A2 and A3.
