Hello,
Check this thread:
Difference between EHS and EHSM
Bassically it says that:
"EHS is the old and existing solution from SAP. It deals with:
Product safety
Dangerous Goods Management
Hazardous substance Management
Industrial Hygiene and Safety
Occupational Health
Waste Management
and
Basic Data and Tools(to support the above sub modules)
EHSM is a new solution from SAP and it deals with:
Incident Management
Risk Assessment
Product Compliance"
But "since 2010, the only license a new customer can buy is the EHSM license. This license gives the customer the right to use the older functionality as well as the newer functionality. "
Best regards,
Natália
