vendor evaluation criteria rejects/complaints

Hi,

    I have configured the vendor evaluation to look at the rejection/complaints sub criteria with the scoring method as 8 = Automatic Determ. from Quality Stat.: Quality Notification. The first time I create a notification, the score drops from 100 straight to 1. Then later no matter how many notifications I create and close with external or internal origin, the score remains at 1. How do I change the score ?

Also is it mandatory to use the Q2/F2 notifications types for vendor evaluation.? What if I create my own Z notification type with origin Q2 ? Will vendor eval still work ?

Thanks
