Exchange rate and revaluation

Friends,

We have requirement to handle multiple currencies(Foreign currency) like USD and AUD.

Does FS-CD use the same exchange rate table as ERP (OB08)?
I think FI will conduct daily foreign currency revaluation, is it the same situation in FS-CD?

How FS-CD handles its own foreign currency revaluation?.

please adivse.

thanks
