Currency Translation Error

Hi Experts,

I am getting an error message at the time of running FX Restatement package.

"

SPRunConversion Version 2.08

Warning : No Rate found in the opening period

ERROR FX-280 Timeid=20080100 - Nothing Extract from Fact Tables "

I saw in the Fact Tables - and the rate exists.

Do you have any idea why the error is coming ?

Can you pls let me know which script logic file from the system library is getting used for Currency Translation ?

Also, i maintained some rules in Business Rules for Currency Conversion Rules.

How this rule get run ? Do i need to trigger somewhere or it is done by default ?

it would be very much appreciating, if i get your valuable inputs on that.

regards,

Samveer
