This blog post is part of a series where we will be looking at a few simple use cases and basics when using SAP BW bridge for Data Warehouse Cloud. The purpose of this series is for you to have a walkthrough of how SAP BW bridge, SAP Data Warehouse Cloud, and SAP Analytics Cloud can work together.

In Part 5, we will be looking at how to transfer your custom ABAP code from your on-premise ABAP system to SAP BW bridge.

Introduction to SAP BW bridge for Data Warehouse Cloud

SAP BW bridge is the latest feature to be released for SAP Data Warehouse Cloud. The main benefit is being able to leverage existing on-premise designs in SAP BW, while also having access to the latest cloud-based functionality in SAP Data Warehouse Cloud. For a detailed breakdown, please head over to the Overview and Technical Deep Dive blog.

Overall Process

Create Repository in Github
Configure trust with your on-premise system
Install abapGit in your on-prem system
Create a new online repository to clone your Git repository to the on-premise system.
Example – Add your custom program to the package and clone with Git repository
Install abapGit Eclipse plugin
Clone Git repository into SAP BTP ABAP Environment

1. Create Repository in Github

Create private repository in https://github.com

Don’t forget to flag ‘Add a README file’ (only then, a branch is created which is needed later)

Copy the URL of your repository

Paste it in a “temporary notepad” – it is needed later

Create a personal access token to authenticate in abapGit to your GitHub repository https://github.com/settings/tokens

Click your user icon in the upper right-hand corner and select Settings. Choose Developer Settings > Personal Access Tokens > Generate New Token

Enter a Note, select ‘repo’ and press ‘Generate Token’

Copy the token and paste it in a “temporary notepad” , it is needed later

2. Configure trust with your on-premise system

Download Git certificates.

Please check the different options to download the certificates here –

https://docs.abapgit.org/guide-ssl-setup.html

Install the certificates on your on-premsie system via the STRUST transaction

Click on the Change button. Open “SSL client Client SSL Client (Anonymous)” folder

In the third box, Certificate, click on the bottom-left button “Import certificate” and “Add to certificate list”. Upload all the downloaded certificates and Save

Optional only for test cases:

Create and Run report ZABAPGIT_TEST_SSL to check if the GitHub repository can be

Read – https://docs.abapgit.org/other-test-ssl.html

3. Install abapGit in your on-prem system

Copy the content of the latest build from the program zabapgit

You will find in the abapGit repository https://github.com/abapGit/abapGit.

For Docs see https://docs.abapgit.org/guide-install.html

Open your on-premise system create a new program like ZABAPGIT via SE38 and paste the saved content into it. Activate and execute the program. abapGit is installed.

4. Create a new online repository to clone your Git repository to the on-premise system.

Create New Online and Paste the URL of your GitHub repository from your notepad

Click Create Package and enter a package name.

Choose an existing package if you want to push objects of that package

to GitHub, see https://docs.abapgit.org/guide-moving-package.html

Click Create Online Repo.

Use your user and the generated personal access token to authenticate to your GitHub repository. You either see an empty repository or the objects of the existing package.

5. Example – Add your custom program to the package and clone with Git repository

In se24 add your ABAP class to your created package as show in the example below.

Click Stage in your abapGit. The ABAP objects in your package appears in your Git repository.

Click Add All and Commit to commit the changes to Git.

Fill in COMMENT and EMAIL ADDRESS and COMMIT. You will be prompted with a credentials popup. Enter your Git repository server credentials and click Execute

After everything went well, you can see the pushed ABAP objects in your Git repository. Go to your online Git repository.

6. Install abapGit Eclipse plugin

In ADT choose in the menu bar Help > Install New Software. Add the URL http://eclipse.abapgit.org/updatesite/and press enter to display the available features. Select abapGit for ABAP Development Tools (ADT) and install the plugin.

Open abapGit repositories

Select your cloud project system in the Project Explorer in ADT and open the abapGit repositories view by opening Window > Show View > Other ….

Expand the category ABAP and select abapGit Repositories and click Open

7. Clone Git repository into SAP BTP ABAP Environment

Click the clone button (green + button) in the abapGit repositories view and Enter your Git URL and your login and password/token.

Select Branch and a Package, where your Git repository should be cloned. (If you have no packages, you need to create a new one before) and click Next.
