If you are evaluating #s4hana conversion for a too long period, it can happen that the conversion (not the product) is not supported any more. FPS2 of S/4 2020 was released 05/2021 and 2 years later the jump is no longer supported (limitation was released on 25.05.2023). 1/2

If you start a conversion project for FPS1 or 2 (almost no one uses FPS0), freeze the tools and use multi-iteration sandboxes, you can expect a runtime of 2-2.5 years (in complex scenarios with problems and optimized downtime). Do major customers have to hurry? 2/2

The release of #s4hana 2023 is close. There will be a 2-year release cycle (next release: S/4 2025) and a 7-year mainstream maintenance. #saphana SPS7 (min. Rev 71) is mandatory! (AS+HDB: SLES15 or RHEL8/9 needed!) Be aware of the details regarding the compatibility packs!

Some news in the context of BW/4HANA: The 2023 release will be published by end of October. Be aware that BW/4HANA 2.0 is only in maintenance until the end of 2024. The new SPS schedule is also in progress for it. => product will have 7 years of support #bw4hana #saphana

A lot of customers currently planning to upgrade to #saphana SPS07 and asking me for a appropriate revision. In my opinion the first Rev. 70 - 72 can only be used in non-prod systems. We are currently testing the latest Rev. 73 but this one has still some HEX performance issues.

Does it make sense that the #saphana certification C_HANATEC_17 (SPS05) has already expired? A product which will be supported until 2025. @SAPLearning

On the other hand, the C_HANATEC_18 (SPS06) certification currently has no expiration date and maintenance will expire at the end of this year. I mean there is still no SPS07 certification available. linkedin.com/feed/update/urn… Details: training.sap.com/certificati…

Have you ever heard of SNC or COD as a feature related to Intel? During a #saphana health check for a customer we found this as default config in the BIOS. This is dangerous for HANA environments! It can cause corruptions. Please check your settings! #geeknews

Intel COD / SNC NUMA feature

Der Einsatz von SNC/COD kann in Verbindung mit HANA zu Performanceproblemen und Inkonsistenzen führen. The use of SNC/COD in conjunction with HANA can lead to performance problems and inconsistencies.

I was astonished that many customers are not aware that maintenance is coming to an end for many products used in the SAP context. Besides #saphana SPS06 also some #vmware products are running out of support. Also note that support for ERP 6.0 EhP 0-5 ends by end of 2025
