Oracle Financials Reference(Technical)?

hi guys,

Would you know where can I have a reference manuals/books/URL for Oracle Financials Setup?

I've just migrated an Apps1103 in a new server,
and its on testing right now, hope fully it can
be live after 2 week. But the current modules
implemented in that Financials is FA and GL.
So I'm sure AP and AR will soon be implemented.

I have acquired a book from QUEU named USING ORACLE APPLICATIONS special edition. And just the same with there other books it all talks about UNDERSTANDING, ADVANTAGES and DISADVANTAGES.... and blah..blah.blah....

What I need is a technical reference for such implementation. I really need to have this references.

Your help will be very much appreciated.

Thanxs in advance.
