SAP BW converts data value currencies ad hoc during analysis, and saves conversion definitions as analysis tools. You can activate and deactivate currency conversion definitions without removing them from the Analysis Tools Manager, enabling currency combinations that differ.
To create a currency conversion definition:
Right-click a dimension member header and select Analysis Tools, then Currency Conversion.
The SAP Currency Conversion dialog box is displayed. Because exchange rates fluctuate, you must indicate the exchange rates and supported currencies for a date. You can use the arrow controls to the left and right of the current month and year, to scroll to another date.
Scroll to the month and year of a date, and click the cell for the date.
In the Select Currency To list, select the currency to which you would like a currency converted.
Your options may be limited to the currencies supported by the date of your exchange rate.
In the Select Currency Rate list, select the exchange rate used to convert currency.
In the Select Currency From list, select the currency that you would like to convert.
Your options may be limited to the currencies supported by the date of your exchange rate.
All data values using the last currency selection are converted to the specified currency, using the specified exchange rate. Repeat this process to convert all data values to one currency.
