Certificate in incoming Quality

I want test certificate from the vendors.And if i will receiv eit at the time of goods receipt,system should not allow me to clear the respective inspection lot.

Accordingly i ahve mapped the things like in QM view, set "QM Proc. active", QM control key - 0005,cert type - E31A and also created the Q. info record for the material vendor combination.

But i found that system is allowing me to accept the material though i am not receiving cert.
