Dear Alberto
REACH SDS is generated with in SAP EHS "classic" (including the topic of "use" handling). SAP Product and REACH Compliance suite does have a different scope. May be change to EHS FORUM with your question. Distribution of REACh SDS to customer is as well supporetd in SAP EHS.
SAP Product and REACH compliance suite can be used to "handle" e.g. the "use scenarios" (communication in the supply chain etc.
Plesse Check SAP online help. Version 2.0 of SAP Product COmpliance Suite is available.
Dear Raja
please address your topic in EHS FORUM. This is the right place to do so.
