Adding flex fields for additional data capture

[Paul Robinson]

Hi,

I am doing an implementation in Australia and our client has a 
requirement to store the ABN and ACN numbers for a company customer, AKA 
Party Group (I think). These fields for companies are localised to 
Australia but probably not just to this one client.

Can anyone recommend the best approach to deal with this scenario, do I 
just modify the party group entity?

Cheers,
Paul
