Extensibility is a broad spectrum, shown in Figure 2

UI adaptations are the focus today – custom fields and tables

On premise – IT is a major player, cloud, it is line of business.  The customers expect to do everything with their system

On the cloud, the system is upgraded continuously

Update cycle on premise is slow; cloud is fast

In cloud – only loosely coupled extensions are allowed; only those that survive the upgrade

On premise – the customer can use modifications

Loosely coupled extensions are decoupled from the core; HCP is not focus of this session

You can still have ABAP and ABAP in Eclipse; in S4 you have more

“Time to value” is key. Design tools for S4 so business users and experts can change the S4 system

Figure 5 shows the basic stack of S4 – database table, application has core data services (data base view for code pushdown to database) and on top is the OData service, then you have reports, UI, e-mail

Create new custom fields and maintain custom logic.

Easier entry point into the way of developing

Figure 6 covers Lifecycle management

On premise – nothing changes; still use classical CTS to create transport requests

Public cloud- transport of objects with Fiori based UI

Figure 7 shows the ABAP Web Editor where you can do ABAP coding in a Web based editor

See the recording for a demo.  In the demo we saw that CDS views that act as queries, and “you don’t need a separate BW system” and “BW is not bad”  – still use, but for just reporting in one system you don’t need BW

Question & Answer:

Q: What is technically behind the business object implementation?

A: behind the scenes, creating a database table, OData service on top of CDS view, BOPF

Q: BRF+ is used to model business logic?

A: Not yet, under discussion

Q: is this badi Fiori app, only for cloud edition?

A: in principle available for both editions; note following cloud first and then to on premise

Q: Which version?

See his blog Extensibility of S/4HANA – Helpful Links | SCN

Q: Will debugging be available in Cloud edition?

A: No

Q: ABAP in Eclipse – connect to Cloud?

A: Behind the scenes, same code; see white paper to build add-ons

Cloud – access via cloud editor; partners could build add-ons

Thank you to the speakers Thomas and Georg and thank you Chris and Peter for moderating
