Upgrade to SAP S/4HANA 2020 – time to change
What is SAP S/4HANA?
SAP S/4HANA is an intelligent, integrated ERP system that runs on our in-memory database, SAP HANA.
Ha, ha, ha just kidding but the slogan comes 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.
How S/4HANA fits into the Intelligent Enterprise
Evolution and Details SAP S/4HANA Software Stack
White Paper – Upgrading SAP S/4HANA – How, Why, and Best Practices
as already introduced the S/4HANA software stack in the Blog – SAP S/4HANA 1709 SPS03 – back on the Mothership again … the are no really big changes in the base components.
still, there is a difference to the SAP BW/4HANA software components stack as follows:
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 …
Information on uninstallation of ABAP Add-Ons can be found in SAP Note 2011192
These Add-On’s can be removed with tx. SAINT before you start the SUM process

SAP S/4HANA – Simplification Item Check
the Report /SDF/RC_START_CHECK is explained in the Blog – Upgrade to SAP S/4HANA 1809 SPSx – the final frontier
coming from lower SAP S/4 Releases, e.g. 1709 you might have to do more checks here …
Note 2679118 – Simplification item check for duplicate output request entries
Note 2927227 – SI-Check – Renovation Task Management parameter in table S4SIC_PARAM
Note 2943919 – Simplification Item Check: Duplicates check for INOB
in addition: a little bit of SPAU/SPDD and and SPAM/SAINT (incl. Kernel) on my side …
Note 2944943 – Wrong Add-On conflict calculation in upgrades and S/4HANA conversions (execute Report RSSPAM_CORRECT_AVERS Version 4)
and hey: remember tx. SDDLAR to check the CDS consistency?
New 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.
Silent Data Migration (SDMI) – new functionality
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.
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.
If this is not possible, you can run the Report R_SDM_ONLINE_EXEC to trigger the migration for a single class manually.
Note 2664638 – Create and assign SDMI User in a client
Note 2949148 – SDMI: Exclude obsolete client 066 from SDMI
Note 2850918 – Authorizations req. for Silent Data Migration (SDMI) in SAP S/4HANA Rel. 1909
Note 2821421 – SDM_USER: Allow creation without SAP_ALL profile
Note 2916801 – Silent Data Migration (SDMI) Configuration Options
Note 2943697 – Handling IN PROCESS class migration
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.
new system behaviour 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 behaviour of the main ans shadow S4 Instance. make yourself familiar with the changes in the Default and Instance Profiles.
using the latest SAP Kernel 7.81
as I’m doing the Upgrade to SAP S/4HANA 20xx 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 7.81/015 (5th of October 2020)
Starting the SUM Process
Please Note the following screenshots are already based on SUM 2.0 SP09, which is the minimum Version to upgrade/migrate to SAP S/4 2020. You will just see the most important screens, as several SUM 2.0 details are already shown in other various Blogs.
