Currency Coversion and Exchange Rate Issue

Question

Hi,
I have a scenario in query which is related to currency conversion and exchange rates.
Company Code     Matter Code      Invoice          Invoice date     Amount     
                    Number          (DD/MM/YYYY)
1001          1111          INV101          01/01/2011     $100
1001          2222          INV202          05/01/2011     $150     
1001          3333          INV303          10/01/2011     $200     
1001          4444          INV404          15/01/2011     $250
Here , Amount field is in GBP currency by default.
User gives choice as USD on selection screen and the amount field is converted to USD in output.
Now, I wonder which day's exchange rate is applied for same ??
And what steps should I do if I want to apply a particular day's exchange rate ??
i.e.
Consider that there are different exchange rates maintained on daily basis.
For each invoice number (INV101 , INV202.....) There is an invoice date (01/01/2011, 05/01/2011...).
The corasponding output amount should take that particular date's exchange rate for conversion of currency.
How to achive same ??
I have gone through t-code RSCUR for same. Nothing helpful found.
I have even gone through some documents for currency conversion., but unable to find out such scenario.
Please help me for same.

Sachdev-
Currency translations are a very complex issue for BW developers. What you need to do is manage a currency translation that is based on the exact 0CALDAY of the transaction. Here are some helpful hints
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/dc43c445-0d01-0010-23a1-ca348ff5f975?quicklink=index&overridelayout=true
The standard SAP business content includes some standard translations as shown in the article, like these:
0MEANTODAY Average rate using actual date (0SY-DATUM)
u2022 0MEANDAILY Average rate using 0CALDAY of the data record
u2022 0TRA_DATE Average rate using 0TRANS_DATE of the data record
u2022 0PSTNG_DAT Average rate using 0PSTNG_DATE of the data record
u2022 0DOC_DATE Average rate using 0DOC_DATE of the data record
However, you MUST have a translation available in the main SAP Currency translation table (Transaction oB08 ) for the period in question, and you MUST report in the appropriate date. If, for example, you wish to report in an aggregate by 0CALMONTH, for example, the currency translation will need to be associated with 0CALMONTH, and the exchange rate will not calculate on a day by day basis, but on the standard that you set for the month. So, to your users, the data will be 'wrong'.
A more robust method involves adding a value field to your data soiurce that uses the currency exchange rate in effect as of the day of the transaction. We do this in our data models, to with:
Mexico Data source:
Each value field will be available in the document currency(whatever), the company code currency(MXP), and in the corporate currency (USD).
Good luck ! Most users don't understand the whole issue, and we spend a bit of time explaining it to them.
