Recently I had some discussions about the SAP Business Application Studio (BAS) and SAP S/4HANA On Premise. Therefore, I have compiled all the sources we looked at during the discussions into one blog post here. This blog post is interesting for you if you are using Web IDE now, and you are thinking about to switch to the SAP BAS. This blog post is also interesting if you have a hybrid IT landscape, i.e. a mixture of cloud and on premise solutions. In this example, you have a S/4HANA On Premise and want to use the SAP BTP to develop Fiori Apps or a SAPUI5 App.

First things first. What is the SAP Application Studio? The SAP Business Application Studio (the next generation of SAP Web IDE) is a powerful and modern development environment, tailored for efficient development of business applications for the Intelligent Enterprise. Available as a cloud service, it provides developers a desktop-like experience like market leading IDEs, while accelerating time-to-market with high-productivity development tools such as wizards and templates, graphical editors, quick deployment, and more. --> Link to the Discovery Center

What is the difference between SAP BAS and Web IDE? --> Link

A very important fact:

SAP BAS is available on the Cloud Foundry environment on SAP BTP

SAP Web IDE is available on the Neo environment on SAP BTP and the Neo environment will be sunset on December 31 2028 --> Link.

That’s why we also talked about how to migrate SAP Fiori projects from Web IDE to SAP BAS --> Link

If you want to use a S/4HANA On Premise and the SAP BAS, the connection between the two solutions is as follows:

S/4HANA On Premise Backend ->SAP Cloud Connector ->Cloud Destination in the SAP BTP Cockpit -> BAS CAP Project -> External Service ->Service Entity -> Fiori App or MDK App to consume the services ->deploy to Cloud Foundry

Now we will look in more detail at the implementation of the individual points of the connection.

SAP Cloud Connector --> Here is an explanation of the Cloud Connector. You need the Cloud Connector to connect a On Premise solution with the SAP BTP. The Cloud connector is providing a secure tunnel between the two environments.

If you want to consume Remote Function Calls (RFC --> Documentation) here is a guide on how to set up your SAP Cloud Connector.

You never developed a SAPUI5 Web App on Cloud Foundry? Here is a guide for you 😊 Along the way, you also learn how to use the BTP and the SAP Build Work Zone.

You want to develop a MDK app (Mobile Development Kit) --> Link

 

Additional informations:

Of course, you want to work in a team on a BAS project, so you must share it. Git is here the best option you have. A guide: Sharing the Project via Git

A lot of persons want to use (existing) CDS views. When it comes to Core Data Services (CDS) views and the SAP BAS:

When it comes to Core Data Services (CDS) views and SAP ABAP you can use the ABAP environment on the SAP BTP:


Link to the Discovery Center for a explanation about the ABAP environment.

Here you have a very recent presentation where where you see how to build a Fiori app on the SAP BTP with the ABAP environment. --> SAP BTP ABAP Environment – How to Build a Multitenancy SaaS Application

I would like to take this moment to thank all my colleagues for the great blog posts and SAP missions they created.
