Upgrade to SAP S/4HANA 2020 – time to change

Blog Content


What is SAP S/4HANA?

SAP S/4HANA is an intelligent, integrated ERP system that runs on our in-memory database, SAP HANA.

SAP S/4HANA is a future-ready enterprise resource planning (ERP) system with built-in intelligent technologies, including AI, machine learning, and advanced analytics. It transforms business processes with intelligent automation and runs on SAP HANA – a market-leading in-memory database that offers real-time processing speeds and a dramatically simplified data model.

Ha, ha, ha just kidding but these slogans come straight from the SAP Website. Nevertheless this Article concentrates on the Upgrade to the latest Version of our Flagship Application S/4 which is (still) the core of all our integrated software applications.

In case there is a mismatch in the naming Support Package Stack (SPS) and/or Feature Package Stack (FPS), please refer to the SAP Release Strategy

SAP Solution Manager and SAP Maintenance Planner

make sure your SAP S/4HANA system is updated in the SAP Solution Manager LMDB and transferred to the SAP Maintenance Planner.

In advance check before the technical Upgrade, if your installed Add-On’s are compatible with SAP S/4HANA. In this case: well, this Add-On cannot be uninstalled via SAINT …

These Add-On’s can be removed with tx. SAINT before you start the SUM process

Check and Preparation Steps before SUM starts

actually before starting the SUM process, I came up with some issues which should be considered, even that I was in a very early stage of the SAP S/4HANA 2020 Upgrade.

SAP HANA 2.0 SP05 Update is necessary

the SAP SUM 2.0 SP09 Version usually checks explicitly the SAP HANA Version which is underlying  and for the Upgrade to SAP S/4HANA 2020 SP05 for SAP HANA 2.0 or higher is mandatory.

Note 2844322 – SAP HANA Platform 2.0 SPS 05 Release Note
Note 2993533 – SAP HANA 2 SPS05 Revision 054.00
Note 3021026 – SAP HANA 2 SPS05 Revision 055.00
Note 3043459 – SAP HANA 2 SPS05 Revision 056.00

Note 3033226 – SAP HANA Client 2.7.26
Note 3027730 – SAP HANA Client 2.8.16
Note 3063656 – SAP HANA Client 2.9.19

furthermore the NSA HANA Functionality which was introduced with SAP HANA 2.0 SP04 is now by default in SAP HANA 2.0 SP05 and SAP S/4 2020 and reflected in the Upgrade by the SUM.

Note 2799997 – FAQ: SAP HANA Native Storage Extension (NSE)
Note 2927591 – SAP HANA Native Storage Extension 2.0 SPS 05 Functional Restrictions
Note 2983008 – Enable/Disable NSE (PAGE LOADABLE) for column tables of HANA statistics server

Silent Data Migration (SDMI) – new functionality

Blog – Monitoring Silent Data Migration (SDM_MON) – S/4HANA 1909 upgrade/conversion

starting with SAP S/4HANA 1909 this new functionality is now present in the System and in every productive client. Despite the fact, that the SUM process takes care about the process, it is more than suitable to make yourself familiar with the Silent Data Migration Functionality, as it is not possible to deactivate or exclude this in further Upgrades.

Job%20RSUPGJOB%20stops%20for%20SDMI

Job RSUPGJOB stops for SDMI

In a Nutshell: from the Start Release SAP S/4 1909 onwards, you will need in every productive client a SDMI user with has the permission to execute the Report SAP_SDM_EXECUTOR_ONLINE_MIGR. the Report can be customized in tx. SJOBREPO individually in every client (default 15 min.) and it has at least to be executed once completely.

tx.%20SJOBREPO

tx. SJOBREPO

If this is not possible, you can run the Report R_SDM_ONLINE_EXEC to trigger the migration for a single class manually.

check inconsistent ABAP managed HDI container

it is suitable to check the ABAP managed HDI container to prevent errors in Phase HANA_DEPLOY_UPG. Depending on your SAP S/4HANA Release, use either tx. SCTS_HTA_TOOLS or Report SCTS_HTA_ADMIN.

Note 2854985 – Check and repair inconsistent ABAP managed HDI container
Note 2906041 – Checks after phase MAIN_NEWBAS/HANA_DEPLOY_UPG were negative!

Changes with ABAP 7.55 Platform

new system behavior with SAP Enqueue Server 2 (ENSA 2.0)

during the complete SUM process in the Upgrade of SAP S/4HANA 20xx the new SAP Enqueue Server 2 (ENSA 2.0) influences the start/stop behavior of the main and shadow S4 Instance. Make yourself familiar with the changes in the Default and Instance Profiles.

SAP Help – Configuration of the Enqueue Server 2
Note 2630416 – Support for Standalone Enqueue Server 2
Note 2754662 – SUM upgrade/Installation of S/4HANA fails due to Enqueue problem

using the latest SAP Kernel 7.81

as I’m doing the Upgrade to SAP S/4HANA 2020 in a very early stage, it showed that the latest SAP Kernel 7.81 help preventing errors in various Upgrade Phases, e.g. ENSA 2.0 usage and CDS handling. Currently 7.81/116 (14th of April 2021)

new Client Copy Tool available

Blog – New Client Copy Tool
Note 2962811 – New Client Copy Tool: General Information

      (Maybe a stupid question, but then again, maybe not)

      Your post seems to imply that after S/4HANA 1909 (1909 as in release Year = 2019 + release Month = 09), the next release is S/4HANA 2020 (2020 as in release Year = 2020 ).

      Can someone confirm that? (Can I read up on that somewhere?)

      It would make a lot of sense to me!

      Thanks

      Hi Joachim, That is correct and has already been officially confirmed elsewhere, e.g.

      Hi Jocelyn Dart ,

      thanks for the link and confirming again.

      As I said, the new naming (4-digit year) makes a lot of sense to me.
      But is that change of naming-logic actually explained somewhere?!

      I'd appreciate a blog "How SAP S/4HANA versions are named", explicitly stating the change in login (as opposed to just using the new name without explanation).
      I have no direct benefit from it, I would just appreciate it and consider it good practice. Getting things (e.g. Names) right is hard, so resources helping with it are nice!

      I myself do make an effort to keep track of names, and using them right!

      best

      Hi Joachim, At this stage there are a just a scattering of early announcements out there. I expect there will be a more formal announcement by SAP S/4HANA leadership of the new naming closer to the general release date which is expected in early Q4 2020 on current planning.

      Hi Said, Usually the Simplification List and technical prerequisites are made available a few days before the new release becomes officially available. Customers who sign up to be part of the Guided Beta program for the new release get early access to these details a couple of months beforehand.  SAP S/4HANA 2020 is currently expected in early Q4 2020.

      Hello Roland,

      Thanks for the detailed steps on the upgrade.

      Could you please let us know what is the minimum HANA database version would require for S4 2020 installation/upgrade? Although I know it is always recommended to go with latest version.

      Best regards,

      Mukesh

      Hello Mukesh Jain,

      whatever you want to do with SAP HANA, you should have at least 64GB Memory at least.

      In my case this is still a quite strong machine with 1TB RAM and 100 CPUs.

      As you can see the Memory usage, it is around 158 GB for a moderate loaded IDES SAP S/4 System. So you should have at least 128 GB, better 256 GB RAM as minimum. the CPU rate is automatically calculated with the RAM.

      Best Regards Roland

      Thanks Roland!

      I could see in screenshot that HANA database version is 2.00.048 that means S4 2020 will be supported on HANA version 2.0 SPS4 and customer no need to go for 2.0 SPS5, Is my understanding correct?

      Best regards,

      Mukesh

      Hello Mukesh Jain,

      probably If you read one of the countless Documents or SAP Notes you will find this Information. Currently there are Issues with SAP HANA 2.0 SP05 and ES despite if you are using SAP S/4 or any other SAP HANA based SAP Application, see - https://twitter.com/JensGleichmann/status/1302968105946230785?s=20

      best regards Roland

      According https://launchpad.support.sap.com/#/notes/2912253 for S/4 HANA 2020 FP00:
      The minimum required revision of SAP HANA 2.0 is Support Package 05 Revision 50. SAP generally recommends customers to implement the highest SAP HANA 2.0 revision available.

      To check PAM before upgrade to S/4 HANA 2020 to prevent bad surprises is advisable.

      One example: actually S/4HANA 2020 seems to be not supported with RHEL 7 any more (in contrast to S/4HANA 1909, where RHEL 7 was supported)  and RHEL 8 seems to be mandatory, when using RHEL in S/4HANA environments.

      OK. I just saw  that hint to PAM is included  in note "2884313 - SAP S/4HANA 2020: Release Information".

      Hello Roland Kramer

      Thanks for sharing your experiences during the upgrade of S4HANA to 2020. Right now I'm performing my own upgrade to the same version and your blog has been useful for me during the resolution of a couple of issues (mainly in phase XPRAS_AIMMRG).

      I had to deal with accessing the system during the Execution phase to create and execute a report (note 2918366 and 2244827), but now the process is running again.

      I hope to share my annotations also (at least the most relevant points) with the community.

      Best regards.

      Andres.

      Hello Roland,

      Nice blog!

      I have a question. We are already in S4HANA 1709 FPS02. Is it possible to upgrade both front and backend systems to S4HANA 2020 FPS01 directly?

      or mandatory to upgrade it to 1809 before moving 2020?

       

      Kindly advise.

      Thanks,

      Bala
