Portugal USGAAP versus Portuguese GAAP

Hello,

We have a company where has a legal entity already for Portugal, but with no relevant transactions. By this reason, this entity was set it up under a common ledger for Eurozone and with a common chart of accounting following USGAAP.

Now, the team is implementing AR invoice issuing but checking localization documentation, we saw SAFT reports uses a PTGAAP (exclusive chart of accounting).

As we cannot change the ledger for now, is there a way to just create a mapping to include the Portuguese accounts and USGAAP accounts without requiring a new ledger?

Can SAFT report execute and extract all accounting entries with the correct Portuguese COA but not creating the new ledger?
