SAP RISE: Proactive Maintenance

Jens Gleichmann • 5. Januar 2025

SAP RISE: Shared responsibility with proactive maintenance

Proactive maintenance for SAP RISE will start now in 2025 with minor tasks like updating SPAM/SAINT and ST-PI / ST-A/PI. For those companies which are familiar with frequent maintenance windows, they are good to have such time frames to hold the systems up-to-date and secure. However, for larger companies where such frequent maintenance windows are not common because every minute of downtime is costly and may only really be necessary once, the situation is quite different.

SAP plans to introduce proactive maintenance running a push update service for selected technology components. The supported components will be announced separately and SAP plans to increase the scope over time.


  • Proactive maintenance will touch only the blue colored figures which represents the technology components
  • Proactive maintenance will be scheduled during a pre-announced maintenance window (customer-specific CMP - contractual maintenance period, or SAP-defined maintenance window)
  • Proactive maintenance will happen only on SAP systems which passed an upfront automated “Maintenance Readiness Check“ (=MRC)
  • Customers and IT partners will be notified upfront via automated e-mail notifications
  • The overall responsibility for patching remains with the customer, specifically for components where SAP provides no pro-active patching



"We understand performing an upgrade/update on the technology components will first be uncritical to your business application, and second, will not lead to request you as a customer to perform any validation after an SAP initiated change"

- Thorsten Hepting SAP ECS -


 If we take this quote serious SAP says if we change only some technology components it will not harm any business application. My 20+ years of tech experience has shown me more than once that changing the operating system, SAP kernel, database or even SAP host agent can affect system stability and business process performance (shout out to SAP HEX engine). The behavior of QAS to PRD can differ significantly due to different infrastructure (number of application servers, sizing, parameter set etc.), data volumes and workloads. The first customer with a special workload who encounters a known issue in the HANA optimizer will gratefully refer to this quote. May be the quote was only in the context of tasks like SPAM/SAINT or ST-PI / ST-A/PI.


Maintenance process

SAP will send out mails to the planned downtime contacts maintained in the SAP for me portal. the changed will be executed in the SAP defined maintenance windows. Those are dates and times defined already in the SAP Cloud Services and which are region specific, having an individual defined date and time for MENA, APJ, Europe and America. On the long side SAP will perform the changes inside the contractual maintenance period (=CMP).

Customers have also an opt-out option to skip a campaign of proactive maintenance due to business specific reasons.

Additionally the affected systems have to pass an upfront automated Maintenance Readiness Check (=MRC). Only if these checks are all green, the deployment will be started. After the maintenance has been successfully finished another mail will be send out. In the end you will find in the SAP for me portal an overview of all the changes pushed by SAP within a new section and that will come in Q1 2025.

All technology components which may affect customer business processes are out of scope for Proactive Maintenance and will stay in full customer control and responsibility. Specifically, this includes Feature Package Stack (FPS) / Support Package Stack (SPS) Updates and Release Upgrades. SAP will continue to support these with on-demand technical execution and consulting based on Customer Service Requests.

=> May be this list should be more transparent which components are meant. S/4HANA FPS and SPS are crystal clear, but what else? The mentioned help.sap.com scope is not accessible for all customers.


CMP - contractual maintenance period

In future SAP will deploy changes in a customer defined CMP windows per system. This time windows will be used by SAP exclusively. This is a formal agreement between SAP and the customer as stipulated in the contract.

Prior to any maintenance, SAP will inform (usually at least 7 business days - source: RISE with SAP S/4HANA Cloud, private edition Supplement enGLOBAL.v.10-2024 ) the customer regarding the planned activities. The customer can request to reschedule the activities but this must be done within 5 days of the notification and must be rescheduled. The activities cannot be rejected permanently.


SAP-defined maintenance windows

For proactive maintenance events where CMPs cannot be used, as a fallback solution, SAP will define maintenance windows. This is possible mainly because this events will all be done as online changes and happening in system uptime.


MRC - Maintenance Readiness Check

MRC is a framework used by SAP to check if systems are ready to receive pro-active software changes. This framework is a new SAP development based on TCI and contains only ABAP repository objects. It's required to collect system data to better prepare upgrade/update procedures. The MRC will be used by ECS only. The MRC repository objects depend only on the underlying SAP NetWeaver functionality and have no dependencies to other components. MRC collects only relevant system informations (Installed Software Components, Database, Used Kernel, Application Servers, ...). MRC does not change anything in the system and uses only its own database tables to store the result of the MRC run.

The framework includes checks on the overall technical situation of the system and on specific qualities of planned software changes. Depending on the results of the checks, MRC categorizes each system as either Red or Green. Only for Green systems (meaning all checks) SAP will perform pro-active changes.


SAP Notes MRC:


  • 3213339 - Maintenance Readiness Checks (MRC) - Central SAP Note
  • 3386693 - Maintenance Readiness Checks - Content Delivery: Version 4 (Q1/2024)
  • 3319026 - Delivery of Maintenance Readiness Checks (MRC)


My questions to this procedure:


  • If a customer always have QCM tables displayed in SE14 no maintenance can be performed means they don't have to opt-out just let one check not pass, right? This sounds like a permanently rejection option. What if customers are not fixing such red system tasks?
  • how and who will get an info for red systems?
  • For project or business frozen zones - how often such a maintenance can be skipped without getting a risk letter and take the full responsibility?
  • Is there a fallback for every maintenance task?
  • What happens if the maintenance window is exceeded? Fallback or early notification for increasing the downtime?


You have also questions to this new pro-active maintenance procedure by SAP?

Why Databases Need Optimizer Statistics – With a Focus on SAP HANA
von Jens Gleichmann 28. Mai 2025
In the world of modern database management systems, query performance is not just a matter of hardware—it’s about smart execution plans. At the core of generating these plans lies a critical component: optimizer statistics. This article explores why databases need optimizer statistics, with particular emphasis on SAP HANA, while drawing parallels with Oracle, Microsoft SQL Server (MSSQL), and IBM DB2.
HANA OS maintenance
von Jens Gleichmann 27. Mai 2025
Please notice that when you want to run HANA 2.0 SPS07, you need defined OS levels. As you can see RHEL7 and SLES12 are not certified for SPS07. The SPS07 release of HANA is the basis for the S/4HANA release 2023 which is my recommended go-to release for the next years. Keep in mind that you have to go to SPS07 when you are running SPS06 because it will run out of maintenance end of 2023.
HANA performance degradation after upgrade to SPS07+SPS08
von Jens Gleichmann 27. Mai 2025
With SPS06 and even stronger in SPS07 the HEX engine was pushed to be used more often. This results on the one hand side in easy scenario to perfect results with lower memory and CPU consumption ending up in faster response times. But in scenarios with FAE (for all entries) together with FDA (fast data access), it can result in bad performance. After some customers upgraded their first systems to SPS07 I recommended to wait for Rev. 73/74. But some started early with Rev. 71/72 and we had to troubleshoot many statement. If you have similar performance issues after the upgrade to SPS07 feel free to contact us! Our current recommendation is to use Rev. 74 with some workarounds. The performance degradation is extreme in systems like EWM and BW with high analytical workload.
The HANA Optimizer is one of the core components of the HANA database. It determines how SQL is exec
von Jens Gleichmann 25. Mai 2025
A database optimizer behaves similarly to the navigation system in your car. You use various parameters to determine which route you want to take to reach a particular destination. Potential additional costs for tolls and ferries also play a role, as do other limitations such as the vehicle's height, length, and width. From these input parameters, the navigation system determines the optimal route based on current traffic information (traffic volume, construction sites, congestion, accidents, closures, etc.), weather conditions, and the length of the route. This means that with exactly identical input parameters, different routes, costs, and thus different travel times can arise depending on the given conditions.
Is NSE worth the effort or is the better question: Do you know your cost per GB of RAM?
von Jens Gleichmann 18. April 2025
Most of our presentations on data tiering projects end with these typical questions: How much we will save? How fast can it be implemented? Is the effort worth it over time? My counter question: "Do you know how much 1 GB of memory costs your company per month or year?" => how much memory we have to save to be beneficial?

More time to switch from BSoH to S/4HANA
von Jens Gleichmann 7. Februar 2025
Recently handelsblatt released an article with a new SAP RISE option called SAP ERP, private edition, transition option. This option includes a extended maintenance until the end 2033. This means 3 years more compared to the original on-prem extended maintenance. This statement was confirmed by SAP on request of handelsblatt, but customers receive more details, such as the price, in the first half of the year. This is a quite unusual move of SAP without any official statement on the news page. Just to raise more doubts? Strategy? However a good move against the critics and the ever shorter timeline. Perhaps it is also a consequence of the growing shortage of experts for operating and migrating the large number of systems.
Optimize your SAP HANA with NSE
von Matthias Sander 15. Januar 2025
When it comes to optimizing SAP HANA, the balance between performance and cost efficiency is critical. I am happy to share a success story where we used the Native Storage Extension (NSE) to significantly optimize memory usage while being able to adjust the sizing at the end. The Challenge: Our client was operating on a 4 TB memory SAP HANA system, where increasing data loads were driving up costs and memory usage. They needed a solution to right-size their system without compromising performance or scalability. The client wanted to use less hardware in the future. The Solution: We implemented NSE to offload less frequently accessed data from memory. The activation was customized based on table usage patterns: 6 tables fully transitioned to NSE 1 table partially transitioned (single partition) 1 table transitioned by specific columns
SAP HANA NSE - a technical deepdive with Q&A
von Jens Gleichmann 6. Januar 2025
SAP NSE was introduced with HANA 2.0 SPS04 and based on a similar approach like data aging. Data aging based on a application level approach which has a side effect if you are using a lot of Z-coding. You have to use special BADI's to access the correct data. This means you have to adapt your coding if you are using it for Z-tables or using not SAP standard functions for accessing the data in your Z-coding. In this blog we will talk about the technical aspects in more detail.
