Dear Soumya
not sure what you are looking for. But my answer is:
a.) EHS supports workflows; and workfloqws act on "change" data, so you have a "trigger" event which you can use
b.) SAP provides a lot of exits etc. One of them you can use to "trigger" additional topics (of what eve
er kind of nature); but you must do the programming on your own. One reference to such an option is mentioned here: EHS User exist for Specification Identifiers
May be check as well: https://www.consolut.com/en/s/sap-ides-access/d/s/doc/YY-EHSS_SPEC_CHECKS
This is the "state of the art" interface to be used if "insert/delte/update" was done and you would like to "trigger" something
