Legal Establishment in Transaction

Good People,

There is One LE in Country X, it has a Legal Establishment in Country X(Primary) and in country Y (Additional) and Connected with Tax Regime of Country Y and still everything works properly? My question for Bill From for AR and Bill To for AP how system will look at this specific Legal Establishment? Normally in Traxn it tracks OU (or its location) or LE (Or its location) and work accordingly. But here both LE and OU Location is Country X. How the Trxn can see Country Y (By connecting to correct Legal Establishment) ?

Any help is much appreciated.
