I guess you know: Enhancement Package 8 for SAP ECC 6.0 is different, from our technical perspective of Software Logistics.
These are the aspects that I am aware of:

 

    1. EHP 8 is an “upgrade”
      SAP Business Suite 7 Innovations 2016 with SAP ECC 6.0 EHP 8 (6.18) is based on SAP NetWeaver 7.50 (NW 7.50), and the procedure is load-based. It is not an update in the sense of the Enhancement Packages (EHPs) until now. It is an upgrade, as the shadow system is created from DVDs, not cloned from the customer system (compare my outdated SCN blog on shadow system: SUM: introduction to shadow system).
      You may check the following SAP notes: SAP Note 2318321, SAP Note 530335.
      Note that with SUM 1.0 SP 19, the Report RSUPG_TADIR_COMPONENT_CHECK (attached in SAP Note 2318321) will be executed by SUM automatically.
      (In the future, the handling concerning DVDs will be simpler: Simplified Download for SUM Procedure.)
    2. Unicode only
      NW 7.50 is unicode-only, and SAP has announced long time ago that the successor of SAP NetWeaver 7.40 will only by offered as Unicode system, and that the path to the successor of SAP NetWeaver 7.40 can only be reached from a unicode system … what was that again? I mean to say that you have to start from a Unicode system to reach NW 7.50 (and to reach EHP 8). For NW 7.50, we do not have a non-unicode kernel. But the SUM procedure to create a shadow system requires the non-unicode kernel for a non-unicode source system. Further one, there is no non-unicode load for the load-based procedure for NW 7.50.
    3. ASCS split
      The SUM will create a separate ASCS instance for the following condition (all have to apply together):

      1. The SUM maintenance activity (like an upgrade) is targeting NW 7.50
      2. The source system does not yet has a separate ASCS.
      3. The source system has more than one instance

 

If the source has just one instance, no specific handling happens. Note that the SUM does not explicitely mention this behavior on the dialog, only in the log files. For SUM SP 17, I can imagine that the ASCS split could be offered as option for target 7.40 as well – just an idea.
[Added on 2016-07-11] Note that with SUM SP 17, for a target based on 7.40, SUM will offer to (optionally) split ASCS.

 

Attention
important side effect for DMO and the (optional) use of an Additional Application Server (AAS, fka DI): if your target for DMO is 7.50, and your system does not yet has an ASCS, and you decide to run the SUM on an AAS (e.g. for better performance), then the SUM will create the (required) ASCS on the AAS. And (strange but true): from the perspective of the SUM running on AAS, the PAS (CI) is handled as a remote dialog instance. DMO cannot handle and cannot start remote instances (other than ASCS), so your CI will not come up at the end of the SUM procedure.

    Hi Boris,

    many thanks for sharing this info. We tried to perform EHP upgrade in sandbox and learned some objects were removed from system during upgrade. Is it like this new approach is causing this deletion of Screens, Index etc.

    These deleted objects are both custom created Z object and some standard objects also.

    Regards,

    Ujjawal

    Hi Borish,

    Thank you very much for the information.

    Let me just confirm one thing and check if my understanding is correct or not.

    Let’s take “updating” from ECC 6.0 EHP7 to EHP8 as an example.

    Does this procedure belong to Upgrade but not Update?

    Please confirm my understanding. Thank you in advance.

    Best regards,
    Mike Han

      Hi Mike,
      my hope was that point 1 of my list answers this question.
      Let me cut out the relevant parts from this paragraph.
      “SAP ECC 6.0 EHP 8 … procedure … is not an update … . It is an upgrade …”
      Best regards, Boris

      Hi Sandip, my recommendation is that this should not be a technical decision, but driven / decided by the line of Business: EHP 8 has extended capabilities. Best Regards, Boris

    Hi Boris,

    Is there any prerequisite in terms of minimum support pack level for an ERP 6.0 System (Also called SAP ERP 2005) to be upgraded to EHP8 SPS6.

    Thanks,

    Ajay

    Hi Boris,

    The SAP Note 2318321, version 33, has an affirmattion about object catalog Add-On´s and I have a doubt.
    The affirmation is “All repository objects which are assigned to packages of such a project AddOn component must be identifiable as customer objects (orginal system <> ‘SAP’ in object catalog entries).”

    We development an Add-On and when it is instlled in customer, in object catalog entries is equal “SAP”.

    Do you know what we are doing wrong?

    I believe that, if i solve this question about catalog of the objects, maybe, I am going to solve my problem of lossless my objects during upgrade of the SAP.

    Best regards,

    Adriana Medeiros.
