hazardous substance management and substance management process difference

Dear Edward

a.) please check SAP online help. Difference is explained there very well. On high level: Basicly Substance Management is encapsulated in EHS component "Basic Data and Tools" (called EHS-BD) and in "Product Safety" (called EHS-SAF). Hazardous substance management is encapsulated in EHS-HSM.

b.) please check: http://scn.sap.com/docs/DOC-41109; reference is given there to a high number of threads dealing with this topic; as well you will find some reference to th "Best practise" approach

c.) please check as well SOA topics; there are SOA solutions dealing "partly" with HSM

In nearly any case you need always basic customizing set up in EHS-BD; then you can use EHS-HSM without EHS-SAF

C.B.

PS: be arwae of the fact that many opeople have "problems" in understanding the term "substance management" / "hazardous substance management" and "Dangerous goods management". Sometimes they us the term "hazardous substance management" but from SAP point of view they talk about "Dangerous goods management"

PPS: terms are e.g. explained in wikipedia and other similar areas.

If you are looking for functionality to manage health and safety processes in operations related to hazardous substances -- meaning approval before chemicals are brought on site, creation of chemical safety instructions for hazard communication, hazardous materials inventory reporting - please look at the new functionality in component extension 4.0 for SAP EHS Management. As Christoph says, this is different from managing hazardous substances in your products and determining if you can ship them and sell them -- such as REACH compliance and DOT shipping requirements.
