Performance degradation after upgrade to SPS07
By Jens Gleichmann 05 Nov, 2024
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.
HANA OS maintenance
By Jens Gleichmann 29 Oct, 2024
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.

RISE with SAP: Roles & Responsibilities
By Jens Gleichmann 24 May, 2024
For every possible RISE with SAP customer it is essential to know the difference of the status quo system construct (on-prem self managed / hosted or managed by a MSP) and the RISE offering with a lot of excluded tasks or tasks with additional costs. If you don't need this tasks, it might be a perfect solution, but our experience is that most customers need some of the services with extra costs.
