Currency code for Sales order creation

Hi experts,

I want to get the query to retrieve the currency codes to be shown when creating an order.

I debugged OEXOEORD.fmb form, which is the form to create a sales order, and got the following query which retrieves 53 rows.

select a.currency_code,b.name,b.description from fnd_currencies a, fnd_currencies_tl b

        where enabled_flag = 'Y'

        and currency_flag = 'Y'

        and a.currency_code = b.currency_code

        and trunc(nvl(start_date_active,sysdate))<=trunc(sysdate) and trunc(nvl(end_date_active,sysdate))>=trunc(sysdate) ;

But i found that the currency code list shows only a few of the currencies in the list and it changes with the price list which i choose.
