Dear Rohan
we need more information
Currently we have two solutions to consider.
a.) SPRC 2.0
b.) Component Extension for SAP EHS Management
(and if you use quite "old" things: "Compliance for product" solution)#
So may be check first these links:
SAP REACH Compliance - SAP Library
and
Component Extension 6.0 for SAP EHS Management – SAP Help Portal Page
and then explain which solution is in your focus.
C.B.
PS: according to my kowledge: for both solution there is no ! "Best Practise" in place
