Connecting from SAP Business Application Studio to SAP ABAP Environment in BTP

Hi Techies,

This post will cover setting up a connection between SAP BTP ABAP Environment and Business Application Studio.

SAP Business Application Studio (BAS) is a new SAP Business Technology Platform (BTP) service that offers a modern development environment tailored for the efficient development of business applications for the SAP Intelligent Enterprise.

In this blog, we will use the Trial account where I will walk you through the steps on how you can use a Booster to Automate the Setup and create a Fiori application. If you have created an instance and service key already? you can skip step 1

You may find a few of the steps redundant or would have seen in other blogs, I wanted to be as detailed as possible to help step by step to connect BAS and SAP ABAP in BTP. Each step heading is self-explanatory, choose the one relevant to you 🙂

A booster is a set of guided interactive steps that enable you to select, configure, and consume services on SAP BTP. For more information, see Boosters.

Let’s get started!

I assume you already have access to your Trial account in SAP BTP and you have created a subaccount and space. If not, follow this guide before proceeding further.

Step 1: Booster to Automate the Setup of the ABAP Environment:

Log on to the SAP BTP trial cockpit and click Go to Your Trial Account.

From your global account page, on the left side, choose Boosters.

 

Search the Prepare an Account for ABAP Trial tile and press Start to start your booster. If you already created a service instance and service key, then please skip this step

Note: Only one service instance can be created at a time.

 

The service instance and service key is created for the ABAP trial user. You will get the below pop up after successful execution.

 

To view the instance and service key, Click on the “Go to Instance” link from the above pop-up

OR

Go to your subaccount -> Select Instances and Subscriptions from the left menu

 

Step 2: Create ABAP cloud project

This step is to create a cloud project in ABAP Development Tool (Eclipse) and add your trial account.

Open your ABAP Development tool from Eclipse.

Do not have it yet? you can download the latest version from https://tools.hana.ondemand.com/#abap.

To create an ABAP Cloud project, open the Eclipse, select File > New > ABAP Cloud Project. 

 

You will get a pop up as below, choose SAP BTP Cloud Foundry Environment > Next

 

Choose your SAP BTP Cloud Foundry Environment Region (e.g: Europe(Frankfurt))  > Enter Email and Password > Next

 

 

Select your Organization (In this case, Trial) > Space (dev) > and service instance > Next

 

Note: The service instance is “default_abap-trial” when you use the ABAP trial booster on SAP BTP. If you create a manual instance, use your own instance name.

 

Click Open Logon Page in the Browser button. Enter credentials if necessary, you will get the below success message

 

Go back to ADT > Click Finish

You can see that the Trial system appears on the project explorer.

 

Step 3: Check the Destination

In your, BTP Subaccount Go to Destinations under Connectivity

 

You will see a destination created with the name “abap-cloud-default_abap-trial-0ca59b7dtrial-dev”

 

It has all the details URL, Client Id, a Client secret to additional properties.

In case you want to set up the destination manually, here are the steps:

Go to Instances and Subscriptions > select your ABAP instance -> Click on ‘>’

 

Copy the below details from your service key:

URL

Under uaa copy : Client ID, Client Secret, and URL(this will be the Token Service URL)

Click create destination and enter the below details:

Name: Enter a name of your choice

Type: HTTP

Description: Enter a meaningful description

URL: enter the URL copied from the service key

Proxy type: Internet

Authentication:OAuth2UserTokenExchange

Client ID & Client Secret: Enter the client id and secret copied from the service key

Token Service URL Type: Dedicated

Token Service URL: Enter the URL which was under uaa in the service key. add “oauth/token” at the end of the link.

For example: in my case, the Token Service URL is: https://xxxxxxxdtrial.authentication.eu10.hana.ondemand.com/oauth/token

Additional Properties:

HTML5.DynamicDestination: true

HTML5.Timeout : 60000

WebIDEEnabled: true

WebIDEUsage: odata_abap,dev_abap,abap_cloud (for further information on the WebIDEUsage property values )

Save the changes

Lastly, check the connection by clicking on the “Check Connection” button. You should see success the message as below.

 

Step 4:Set Up SAP Business Application Studio for Development

From SAP BTP, navigate to the security > Trust Configuration > Click on Default identity provider on the subaccount overview page

 

Enter your email id and click on “Show assignments”

 

Look for the “Business_Application_Studio_Developer” role. If it is not there, continue, otherwise, you may skip the below two sub-step

To add the role: click on the Assign Role Collection 

 

Search Business_Application_Studio_Developer > Select > Click Assign role collection

Go to Service Marketplace and search for SAP Business Application Studio

 

If not created, click on create button to launch the wizard for subscribing to SAP Business Application Studio. and click on Go to Application.

 

You will be navigated to a new tab, SAP Business application Studio Loads.

 

Step 5: Create a Dev Space

Click on “Create Dev Space” button > Select SAP Fiori > Enter your dev space name > Click on Create Dev Space

When your status is Running, select your dev space -> In this case, it’s MyDev.

 

Step 6: Set up your Organization and Space

In your dev space, select the open folder to set your workspace > select projects > Click Open

 

Select View > Find command > search for CF: Login to Cloud Foundry and select it

Select your API end point > Enter > enter your email address > Enter > enter your password > Enter

 

Choose your Organization (trial) > Space (dev) . You will see a success notification

 

Step 7: Create a list report page by getting Odata from ABAP BTP

Select View > File Command > select Fiori: Open Application Generator > List Report Object Page > Click Next

Enter below details:

Data Source: Connect to an SAP System

System: Destination abap-cloud-default_abap-trial-0ca59b7dtrial-dev as seen in Step 3

Service: If all set up fine -> You can see the list of available Odata Services.

 

 

Let’s Continue and create a List report object page

Choose your Odata Service. In my case I choose ZUI_C_TRAVEL_M_XXX > Next > Select entity as TravelProcessor > Enter module name > Application title > Description > Add deployment configuration: “Yes” > Add FLP configuration: “Yes” > Configure advanced options: No > Next

 

On the next page, you need to provide TR and package. for that you need to log in to the ADT tool > Search your package “ZTRAVEL_APP_XVG”  and open it. Open your transport organizer tab, under “Modifiable” folder” you can see your transport request (TR)

 

Fill in the additional required details > Click Finish

Once finished you will receive see a notification as “The files have been generated”

Run the application and Preview the data

Click Run button on the left side and start your application -> you will see in the terminal that the server is started.

Note: If you have blocked pop up, you may receive a notification as shown in screenshot > Click Open

 

 

Your default browser will open. Click Go to see your result.

 

Voila!! We have come to the end of the blog.

You can further deploy the application, add features & functionalities. The sky is the limit.
