Need to Display Currency description in Crystal Enterprise Report

Hi Experts,

I created a report on BEx query and need to show the amounts in this format  Amounts in Document Currency = 2578.00 GBP and Amount in Group Currency = 2200.00 USD but in my report it is showing like this

Amount in Document Currency  = £ 2578.00 and

Amount in Group Currency = $ 2200.00.

Is there any formula/function or any option that i can use to convert the symbols into currency description/abbreviation.

Thanks in advance,

Shehzad
