Define values for hazardous material numbers in Material Master/Product Master (Cloud implementation)

Hi,

We are implementing S/4HANA Cloud. In the product master under Storage there's a field "Hazardous Material Number". The same field is available in the Change Material app (old MM02) in view "Plant data/stor 1". My customer wants to define data for this field, but we cannot find how to maintain the possible values. Does anyone know how this can be maintained in the Cloud?

Regards,
