This is an update to the 10 year old ABAP Object Oriented eLearning series. What started as an update to improve the video resolution also turned into modernizing the tooling and ABAP syntax used to teach the basic Object Oriented concepts. Here is the YouTube Playlist that goes along with this code sample: https://youtube.com/playlist?list=PL6RpkC85SLQB-vyEFpUj1xkrIhH4UiV4D

Requirements

Make sure to fulfill the following requirements:

• You have access to an SAP BTP, ABAP Environment instance (see here for additional information).
• You have downloaded and installed ABAP Development Tools (ADT). Make sure to use the most recent version as indicated on the installation page.
• You have created an ABAP Cloud Project in ADT that allows you to access your SAP BTP, ABAP Environment instance (see here for additional information). Your log-on language is English.
• You have installed the abapGit plug-in for ADT from the update site http://eclipse.abapgit.org/updatesite/.

Download and Installation

Use the abapGit plug-in to install the ABAP OO Examples by executing the following steps:

1. In your ABAP cloud project, create an ABAP package for the demo content to be downloaded (leave the suggested values unchanged when following the steps in the package creation wizard).
2. To add the abapGit Repositories view to the ABAP perspective, click Window > Show View > Other... from the menu bar and choose abapGit Repositories.
3. In the abapGit Repositories view, click the + icon to clone an abapGit repository.
4. Enter the following URL of this repository: https://github.com/SAP-samples/abap-oo-basics and choose Next.
5. Create a new transport request that you only use for this demo content installation (recommendation) and choose Finish to link the Git repository to your ABAP cloud project. The repository appears in the abapGit Repositories View with status Linked.
6. Right-click on the new ABAP repository and choose pull to start the cloning of the repository contents. Note that this procedure may take a few minutes.
7. Once the cloning has finished, the status is set to Pulled Successfully. Then refresh your project tree.

As a result of the installation procedure above, the ABAP system creates an inactive version of all artifacts from the demo content

To activate all development objects from this sample:

1. Click the mass-activation icon (Activate Inactive ABAP Development Objects) in the toolbar.
2. In the dialog that appears, select all development objects in the transport request (that you created for the demo content installation) and choose Activate.

Known Issues

In the ABAP Trial on SAP Business Technology Platform you sharing an ABAP instance with many other users. Only one user on this system may import this sample as all object names must be globally unique. If you receive an error that the objects already exists upon import, search the system for classes named ZCL_OO_TUTORIAL*. Someone has already imported the content in your trial system and you can simply start with that imported version.
