ERPstuff - Oracle EBS Community

hello,

We are intending to reimplement our business suite.The requirements are :
create a new chart of account
create a primary new set of books with USD as the currency
create new reporting set of books with the local currency as the currency.

Can we be sure that the local currency can be used in purchasing prices, invoices and paying the suppliers?

and also create flexfields for special information& extra information. so we create key flexfields& discriptive flexfields
