Dear Tarun
please confirm that you would like to use this SAP EHS component:
Hazardous Substance Management (EHS-HSM) - SAP Library
If answer is yes: there are some threads in this FORUM. But the use etc. in industry of this solutions seems to be limited. I am not aware of a "Best Practise" document
Examples are:
http://scn.sap.com/thread/3454822
Blocking Hazardous Materials for Purchasing with HSM
Besides HSM, what needs to be configured to activate the SARA 311 312 reports?
HSMR01: Error when generating a change number
hazardous substance management and substance management process difference
SAP Hazardous Sub.Management Urgent
Triggering of EHS master data from MM
Hazardous Substance Management
Hazardous Substance Management
Save NFPA (National Fire Protection Association) Diamond Data in SAP
In many cases SAP consultants "mix" the use of EHS-BD etc. with the use of "EHS-HSM"; and there is now some kind of overlap in "Component Extension for SAP EHS Management".
To my knowledeg there is as well imited information on this component on SAP Marketplace. I am nor aware of any kind of "consulting OSS" note.
