Who has Tax Books in JDE Fixed Assets?

We are currently using a different software for our Fixed Assets and are seriously considering switching to JD Edwards.  We currently use JDE Financials only.

There are questions around the management of the Tax books in Fixed Assets that remain for us to be able to complete the decision.  We are a business operating in multiple states that handle bonus depreciation differently; so we currently have extra books to accommodate those differences; ie Oregon has its own tax book.  We would like to know how other JD Edwards customers are using Fixed Assets to manage calculations and reporting for Tax.
