vendor evaluation without weighting key(ME6E)

Hi All,

Can anyone explain me how the system is selecting the vendors without weighting key - transaction code ME6E.

In my case when i use this tranasction, Message "Weighting key mainatined for all selected vendors" appaers even though i haven't maintained weighting key for all the vendors.

Even i created new vendors and tried again, I am getting the same message .

Can anybody help me out.

Points rewarded for helpful answers.

Thanks in davnace
