🟢 Dealing with Legacy Code and Transactional Consistency in RAP

The ABAP RESTful Application Programming Model (RAP) offers a set of concepts, tools, languages, and powerful frameworks on the ABAP platform to efficiently build innovative and cloud-ready SAP Fiori applications and Web APIs from scratch or by reusing existing code. RAP is available on SAP BTP ABAP Environment (aka Steampunk), SAP S/4HANA, and SAP S/4HANA Cloud.
But which legacy ABAP code can be reused in RAP? What must developers do to ensure the transactional consistency of the SAP Logical Work of Unit (LUW) when working with RAP? These questions and more will be discussed in this webcast.
Guest Speakers:
Marcel Hermanns, RAP Product Owner
Renzo Colle, RAP Lead Architect

Thank you for the explanations @Renzo Colle, it's very clear now about Transactional Consistency with remote communication

Thank you for this! Super cool video! A+++

Question: For the Different options for Development in SAP S/4HANA On-oremise edition you mentioned ABAP Cloud and ABAP Classic... on that regards, there is a plan for SAP to decommissioning ABAP Classic technologies like WebDynpro, Dynpro, Module Pools, ALV, etc in the future and push every custom extensions to be cloud ready?

[@sapdevs]

ABAP classic techniques are already not allowed when using ABAP Cloud. These new rules are enforced automatically in S/4HANA public cloud and SAP BTP, ABAP environment. They remain optional in on-premise and private cloud. However, you can choose to turn the new checks and restrictions on - even at a package level. This way new development will enforce no usage of old technologies. Meanwhile your existing development can continue to live beside it (and be maintained) without the stricter checks.

@@sapdevs thanks for the answer… but my question is on regard of the strategy in the long run… will sap in the future replace the classic Abap technology with the new Abap cloud technology and no longer support the classic extensions at some point in time?

the part explained by Renzo Colle isn't very clear to the users!
