Dear Devdatt
you need first to understand the business need of a "Hazard inducer". E.g. if oyu have a DG record for IATA or ADR for IATA may be you have a "Hazard inducer" but for ADR not; so I am not sure what answer you would like to get.
If you use "filling" then the Hazard inducer is maintained normally on REAL_SUB level in property "Hazard Inducer". Here no standard search exit is delivered by SAP; but you can genereate a "search" user exit so that you could answer the question like "Where used".
I am sorry to say that as well there is no suitabel "output variant" available. But you could as well generate/prepare one. Then you could generate a hit list in CG02 use the output variant and you get a "mass" download of the "hazard induceer" if they are maintained; only con: the download is "REAL_SUB" related and not material related.
What is the business need of your question?
C.B.
