Cenvat Credit -short qty received

Hi I wud like to know the procedure for following : In case of material qty received short against a invoice raised by the supplier then in such case what shd be the right method to follow: Option 1: Book invoice for actual recevied qty and claim cenvat only related to actual receipt or Option 2: Book full value invoice irrespective of short qty receipt and then raise debit note for short qty. In such case then since no material is going out of the factory can excise invoice be raised or simple debit note will suffice? Prashant
