Thanks SS for update, first note says solution when switching from SAP Utilities to IS OIL when activating and second note says integration of utilities and IS OIL/GAS.
still having doubt, when I install SAP ERP6.0 with EhP7 can I directly activate IS oil or needs to be upgrade any SPs. Some threads sys IS OIL only included needs to be upgrade SPs and Inst. Guide says IS OIL component will come with 617 release level..
