ABAP Platform for SAP S/4HANA 2020
SAP S/4HANA 2020 was released on 7th of October to the SAP customer base.
ABAP Platform 2020 is the technology platform underlying SAP S/4HANA 2020 and is shipped as part of SAP S/4HANA 2020. In addition, ABAP Platform 2020 is part of SAP S/4HANA Foundation 2020 for SAP HANA-only Add-Ons.
ABAP Platform 2020 is not shipped as a standalone product. ABAP Platform 2020 consists of the AS ABAP, the ABAP Development Tools (ADT) in Eclipse and several additional technology components which are required to run SAP S/4HANA.
Previous SAP S/4HANA versions such as 1511, 1610, 1709, 1809 and 1909 can be upgraded to SAP S/4HANA 2020 which is based on ABAP Platform 2020.
ABAP Platform 2020 delivers innovations for the ABAP stack in different areas.
One of the major investment areas in the ABAP Platform is the ABAP RESTful Application Programming Model (RAP). RAP is the evolutionary successor of the ABAP Programming Model for SAP Fiori. It includes essential extensions of the ABAP language, development tools and frameworks which enable the efficient end-to-end development of intrinsically SAP HANA-optimized SAP Fiori applications and web services in AS ABAP. With ABAP Platform 2020, the ABAP RESTful Application Programming model now supports the managed scenario for developing greenfield applications with draft support, extended determination / validation support, extended optimistic locking (ETag), managed early numbering based on UUIDs, extended feature control and authorization.
ABAP Development Tools in Eclipse in ABAP Platform 2020 further improve developer productivity through support for BAdIs definitions and implementations, various source code editing enhancements like an editor for number range objects and support for the new CDS view entities. CDS view entities are the successor of CDS DDIC-based views and offer extensive and enhanced features. SAP recommends using CDS view entities instead of CDS DDIC-based view due to technical improvements, such as performance at activation, and so on. CDS Test Double Framework and ABAP SQL Test Double Framework also provide test support for CDS view entities.
Additional enrichment in the connectivity area is the support for Advanced Message Queuing Protocol (AMQP). The AMQP protocol was established to support robust and asynchronous messaging between various applications. The ABAP Platform 2020 provides an API to implement AMQP clients for ABAP applications. Using such an AMQP client, ABAP applications become able to exchange messages with other AMQP clients point to point or via a broker.
ABAP Platform 2020 offers also comprehensive enhancements in code analysis tools. The SAP Fiori Custom Code Migration App was extended to support custom code migration for SAP S/4HANA greenfield projects and enriched with the complexity analysis dashboard. Complexity analysis enables customers and partners to spot the top complex executables and development packages in custom code in order to identify candidates for redesign to save upcoming adaptation effort and future maintenance costs. The results of custom code analysis can be now uploaded to SAP Readiness Check 2.0. The Quick Fix comments in the ABAP Development Tools in Eclipse are targeted to keep the original source code after the semi-automated adaptation of custom code with Quick Fixes.
The SAP S/4HANA in-app extensibility was further optimized in the ABAP platform 2020 by offering support for XCO (“Extension Components”) library for efficient development experience and providing further improvements for custom business objects and custom fields and logic.

Thanks Olga!
I heard from Andre Fischer that OData V4 support for RAP will be delivered with a feature pack.
Are there plans that more features will be down ported or is this a onetime shot?
Thanks,
Stephan
Hi Stephan,
it can happen, that some features will be down ported as well over time. It depends on the customer need, technical feasibility on older release, our development capacity etc.
Regards,
Olga.
Thanks for the great blog. Quiet a lot informative.
But, ABAP RAP can't be used already in 1909 version on-premise ?
Hi Rodrigo,
correct, RAP can be already used in the SAP S/4HANA 1909 on-premise.
Please note, that with the 1909 shipment RAP was delivered with reduced feature scope, focusing on the read-only apps and the development of unmanaged transactional apps based on existing application logic.
With ABAP Platform 2020, the RAP feature scope was significantly enhanced now supporting the managed scenario for developing greenfield applications and draft handling.
See for details the overview presentation linked in the blog above.
Kind Regards,
Olga.
Thanks,
"No standalone ABAP platform installation supported"
What does this entail?
Any impact on the SAP NetWeaver AS ABAP Developer Edition?
Customers running a standalone productive ABAP system, without business logic, will they be able to upgrade?
It seems that NW is basically dead and replaced with ABAP Platform (available only for S/4HANA).
Check https://blogs.sap.com/2020/06/12/abap-platform-part-1-evolution-from-sap-netweaver/
okay, then if ABAP platform cannot be installed standalone, I wonder if there will be a developer edition?
Hi Lars,
it goes in the direction of offering the SAP Cloud Platform ABAP Environment Trial as modern trial environment for discovering new ABAP platform features. The last developer edition on-premise is AS ABAP 7.52 (currently SP04).
Regards,
Olga.
Update: the latest is now https://blogs.sap.com/2021/02/15/sap-abap-platform-1909-developer-edition-available-soon/
I ask myself the same thing, Lars Hvam . Besides, I'm a little worried 😉 An affordable test environment is a must. Better still a free test environment.
If the environment is overloaded, it becomes difficult to concentrate on ABAP. At the moment I'm concerned that it will be more and more difficult to "just" teach ABAP to students for example.
It's perhaps not a big thing to lower the entry barriers for ABAP beginners when you are a company (own systems, send your employees on courses and more). But students and just interested people have to solve many problems before they can have a look at ABAP 🙁
I'm curious.

Q&A
Minor Edit, but in the referenced presentation "ABAP Platform in SAP S/4HANA 2020 – Overview and Product Highlights." - There is an error on page 16 with the link to the documentation for the Logon Pad. It's pointing to the DRAFT version instead of the released version. 😉
Hi Filipe,
thanks for noticing that ☺️. I've corrected the link.
Regards,
Olga.
I must apologize, because I failed to add an important comment at the end: This article and all of the related articles in the presentation were outstanding. It's not often that articles, presentations and additional documentation is so thoroughly researched and presented. It is greatly appreciated!
Thank you, Filipe, appreciate your feedback!
Hello Olga,
Nice blog as usual!
I have a question. We are planning to upgrade our existing S/4HANA 1709 FPS02 systems to 2020 FPS01.
Is it possible to upgrade both Fiori and S4 systems directly to 2020 or we have to upgrade it to 1809 first?
Kindly advise.
Thanks,
Bala
Hi Bala,
you can upgrade from SAP S/4HANA 1709 FPS02 directly to the SAP S/4HANA 2020 FPS01.
Best Regards,
Olga.
Hi Olga Dolinskaja,
as describe in SAP Note 2912919 - SAP S/4HANA FOUNDATION 2020: Release Information Note - SAP ONE Support Launchpad, SAP S/4HANA foundation can only be used in combination with some specific AddOns, for instance for the FES 2020 for S/4HANA (as embedded installation).
I ask myself, if the usage is only restricted to the listed products or if it is allowed to install customer and partner addons too (e.g. I have a S/4HANA foundation with FES2020 - which is allowed; am I allowed to installed partner addons on that system). I guess not 🙂
If it would be allowed, is there a roadmap how long S/4HANA Foundations are supported/provided for the constellations described in the note?
Thanks,
Florian
Hi Florian,
the SAP S/4HANA FOUNDATION 2020 can be used only with Add-Ons, which are listed in the corresponding release SAP Note.
Kind Regards,
Olga.
Thanks for any of your blogs Olga 😉
I am already looking forward for your new blog titled ABAP Platform for SAP S/4HANA 2021
Kind Regards,
Sergio
Hi Sergio,
thank you, the 2021 blog will come soon, stay tuned 🙂.
Best Regards,
Olga.
