The ABAP RESTful Application Programming Model (RAP), aka ABAP RESTful Programming Model, is generally available in the cloud on SAP Business Technology Platform (BTP) ABAP Environment – formerly knows as SAP Cloud Platform ABAP Environment – as well as on-premise on SAP S/4HANA, starting with edition 1909. This blog offers a collection of materials (e.g. presentations, tutorials and videos) to get started with the topic, and will be updated regularly. |

Introduction |
The ABAP RESTful Application Programming Model (short: RAP) offers developers an efficient way to build enterprise-ready, SAP HANA-optimized, OData-based Fiori UI services and Web APIs in the cloud as well as on-premise. It is the evolutionary successor to the ABAP Programming Model for SAP Fiori.
The ABAP RESTful Programming Model is generally available in the SAP BTP ABAP Environment, and now also in SAP S/4HANA starting with the edition 1909. The feature scope in SAP Business Technology Platform (BTP) ABAP Environment – formerly known as SAP Cloud Platform ABAP environment – is enhanced on a quarterly basis on defined dates, while new capabilities are delivered in SAP S/4HANA on a yearly basis with new on-premise editions.
The greenfield development of OData-based services – i.e., starting from scratch – is supported with the so-called managed implementation type, whereas the brownfield development – i.e., based on existing code – is supported with the so-called unmanaged implementation type.

ABAP Flight Reference Scenario |
The ABAP Flight Reference Scenario is a new data model intended for demo purposes and use in training courses – mainly in the context of the ABAP RESTful Application Programming Model (RAP). It is a reloaded and adapted version of the well-known SAP NetWeaver Flight data model.
The ABAP Flight Reference Scenario offers several examples that can serve as reference implementations of the various capabilities provided by the RAP. It is not an integral part of the ABAP platform, but SAP – i.e. the ABAP Platform team – makes it available and provides updates on GitHub. Therefore, it must be imported into the relevant ABAP systems before use.
The ABAP Flight Reference Scenario is available by default and ready for use on the free SAP BTP ABAP environment trial.

Nice collection,all in one place. Thanks for your efforts.
Do you know where we can find the list of whitelisted objects for ABAP PaaS (availability), the list must be growing.
Hello Salil,
Thanks for the feedback.
You can use one of the following options to gain an overview of the released objects in SAP Cloud Platform ABAP Environment:

Hi Carine,
I can see Rest ABAP Programming Model in SAP S/4 HANA OP 1809 FSP01 version for all ACR reports. Can we develop ABAP Restful services in 1809 OP version too or is there any restriction?
Thanks Carine! Where do I find info or documentation about the new change document API.
Is is part of the 2019/11 shipment?
Hello Stephan,
Thank you for your feedback.
Yes, the Change Document Solution has been released with the 1911 shipment.
More information about it can be found in the online documentation. https://help.sap.com/viewer/65de2977205c403bbc107264b8eccf4b/Cloud/en-US/741220a1097d4b6ebff3a09c0dd35627.html

A very nice entry point into that topic, thanks a lot Carine!
Thanks Carine !!!
Carine Tchoutouo Djomo - Couple of questions on this model and strategy that SAP is moving towards:
Hi Raj,
you‘re welcome.
Let me go through your questions.
SAP opted for a cloud-first shipment approach of RAP, but it is also available on-premise starting with SAP S/4HANA 1909.
Currently only the unmanaged implementation type for brownfield application development based on legacy business logic is supported in SAP S/4HANA. The feature scope will be enhanced with the next major SAP S/4HANA release in 2020. It will comprise the managed implementation type for greenfield application development.
The RAP feature scope is enhanced on a quartely basis in the SAP Cloud Platform ABAP Environment.
With RAP, a new ABAP artefact, the Service Definition (R3TR SRVD), has been introduced to enable a protocol-agnostic service scope definition. A service definition is highly reusable. Its binding to a given protocol and a given scenario – i.e. UI service or Web API – is done with a Service Definition (R3TR SVRB); a new ABAP artefact.
Beside that, the ABAP language has been enhanced in order to support natively the implementation of transactional BO behavior (create, update, delete,). It means that no additional framework is required for that. In the ABAP Programming Model for SAP Fiori, the CDS-based Business Object Processing Framework (BOPF) was neede for the transactional BO handling.
I hope this information will be helpful to you.
Kind regards,
Carine
Dear Carine,
do you have any news, if the managed scenario will be shipped with a Feature Package for S/4 1909?
Or is it planned to be delivered in S/4 20xx edition?
Thanks,
Stephan
Hi Stephan,
The current plan* is to enhance the RAP feature scope in the SAP Cloud Platform ABAP Environment on a quarterly basis and in SAP S/4HANA on a yearly basis.
The managed implementation type for greenfield application development is currently planned* to be delivered on-premise with the next major SAP S/4HANA release in 2020.
* This is the current state of planning which may change at any time without further notice from SAP. Find more information in the ABAP Platform Roadmap - which will be updated very soon.
Kind regards,
Carine
Hi Carine,
Could you please clarify the below queries?
"Currently only the unmanaged implementation type for brownfield application development based on legacy business logic is supported in SAP S/4HANA. The feature scope will be enhanced with the next major SAP S/4HANA release in 2020. It will comprise the managed implementation type for greenfield application development." - Does this mean that 'managed scenario with un-managed save' is not available in an on premise SAP S/4 HANA 1909 ?
I wanted to try the same('managed scenario with un-managed save') for a POC.
Is it available in SAP S/4 HANA Cloud 1909?
Regards,
Vivek.
Hi Carine,
I am looking for limitations in terms of (Draft, Authorizations, Locking) of un-managed implementation with On-Prem 1909 version. Do you have any help document on this topic?
Thank You
Saurabh
First of all, congratulations and thank you so much for such a wonderful feature.
You mention this is available on S/4 HANA, but I would like to know if it's also available on Solution Manager? I would like to develop something for our on-premise Solution Manager also.
Thanks a lot,
Bruno
