Vendor Evaluation Period Selection

Dear Sir,

We use ME63 for Vendor Evaluation , here we do not find any option to give the period over which Vendor should be Evaluated . We have a requirement that Vendor Evaluation must be based upon the Purchases made during period 1-DEC-2007 to 31-DEC-2008 .

Kindly guide us , as how can be achive it please .
