BI & ECC data not matching after currency conversion

Hi All,

I am using currency conversion in one of the report. when i reconcile the report with ECC there is some difference in converted amount. BI & ECC Amount are not matching.

my cube contains only 0FISCPER (Fiscal year / period) time characteristic and the conversion type is based on:

Exchange Rate type: M

Variable time reference: Beginning of period

Standard Object: 0FISCPER

Please help.

Regards,
