We copied a SAP ECC 6.0 system SPS 17 and would like to update this system to EhP4.
1) Which software components do I need to download from SAP service marketplace?
2) Are the EhP software components (SAP_ABA, SAP_BASIS, etc.) cumulative?
I mean when I do a update to EhP4, do I need all the EhP predecessor versions (EhP1, EhP2,) or only the EhP3 components?
Thank you very much!
