cost calculation error while creating production order

Hi, "version 0 is not defined in controlling area xxxx for the fiscal year 2008, maintain the fiscal area dependent version parameters for the version o".the above error message appears at the time of saving my production order with co01 t-code. i have tried to rectify this by okez t-code, but it gives message that "activation of the indicator is notallowed". the same message appears while releasing the order, while doing the GI . Pls suggest.
