Hazardous Material warning at GR

Hi All

I have activated hazardous material management in our test client and have set up a hazardous material and attached it to a standard dangerous material (it's a flare)

I was expecting a warning message at point of goods receipt using MIGO but throughout the TR creation, TR to TO generation and TO confirmation I didn't get any notification that the material was hazardous.

Where can i configure SAP to advise material is hazardous and inform me of the storage class?

We do not have any putaway or picking strategies and out warehouse setup is generic (no storage types/storage sections or fixed bin used)

Any assistant appreciated

Thanks in advance
