Exch.rate type

Hi,

According Russian legislation need to do posting for all operations in foreign currency using exch.rate set by Cental Bank of Russian Federation.

Currently when we try to do posting in EUR, system uses exch.rate type EURX, which is managed not only by Russia and sometimes is different from needed exchange rate.

So, need some change in customizing to start using exch.rate type M.

And also, any authorization change or org.procedure change, that will prevent change of this exchange rate by non-Russia users.

So, what are the configuration have to do for this?

Thanks in advance.
