Multicurrency in CRM/300 integrated system

I posted this question in the integration forum but I've had no responses.

Multicurrency in an integrated CRM/300 system - Sage 300 for Sage CRM Integration General Partner Discussion - Partners - Sage City Community

I have a CRM 2020 R1 system integrated with a Sage 300 2019 system. There are 4 companies in 300 synced with CRM. CRM was installed and is configured as a single currency system. If I change that value to enable a multicurrency system, does that have any effect on anything with the Sage companies?

I know that CRM will display the currency based on the user preferences and I know that the exchange rate is fixed unless someone updates it.

Any help here would be most appreciated
