Dear all
only small add on:
the term "SPRC 2.0 is a predecessor of the EH&S Management Add-On" is not a good one.
The "Component Extension of SAP EHS MAnagement " can not ! take care all of the many processes existing in SPRC 2.0; only some aspects have been transferred from one solution to the other. Currently i would assume that no additional transfer is planned. as SAP will concentrate on S/4 HANA roadmap.
On the top: the "Component Extension" is based on completely different data model, Userinterface etc.
With version 6.0 once again some redesign has been done and thes solution can now support on top processes (and therefore the old SAP solutions can be removed/transferred to new solution)
Please check the Online help
