Add a Model and Test the SAPUI5 App

Define a new data source which references the created OData service and use it for the default model.

You will learn

Now that you have set up a destination in the SAP Cloud Platform cockpit, you will connect that destination to your application.

There are three steps to connect the OData service to your application.

  1. Define the Data Source in your manifest.json file.
  2. Create a Model. (The Model is the data source, based on the Model-View-Controller architecture).
  3. Test the application

Step 1: Open the descriptor editor

In a previous tutorial the OData test service called “Northwind” was set up for all SAP Cloud Platform applications. Next, this specific application must connect to that “Destination”.

  1. Open the mta_app/app/webapp/manifest.json file with the Descriptor Editor, by double clicking on the file.

    If you open the file, and you get a code editor (and not the form editor shown below), click the Descriptor Editor link at the bottom of the page. This will change to the Code Editor.

  2. Click the Data Sources tab at the top of the screen.

  3. Click the + icon next to the Define OData services for the application and… box.

Step 2: Define the Data source
  1. From the Sources list, choose Service URL.

  2. Then choose the following:

    Drop-down Box Northwind Sample OData
    URI /V2/Northwind/Northwind.svc
  3. Click the Test button to test the service. If the data is correct, you should see the service entities appear.

  4. Click Next to continue.

Step 3: Use the data source as default model
  1. Keep the default value Use default model to use this data source with the default model.

    Finish creating the OData service
  2. On the confirmation screen, click Finish.

Step 4: Test the application in the Cloud Foundry environment
  1. To test your application, click on webapp in the project tree, followed by a click on Run Run Icon

  2. Choose the index.html file to run and confirm with OK.

  3. In the console, you should be able to see that the test deployment started.


This initial deployment might take a couple of minutes. But don’t worry, the next deployment will be super fast!

Step 5: Inspect the application network trace
  1. You might see this logon screen. If so, please log on with your SAP Cloud Cockpit credentials.

  2. Now you should see your (blank) SAPUI application. Right click on the web page, and choose Inspect

    Google Chrome inspector tool
  3. The inspector will appear. Click on the Network tab to view the network traffic for the application.

    network tab in the inspector tool
  4. To view all the network traffic, reload the page.

    The network traffic will appear as the page is loading…

    What about the red text? Several files will appear in red. This is normal, as we have not set up that part of the application.

  5. Scroll down until you find the $metadata item.

    NOTE Typing in metadata to the filter box in upper right corner will make it easy to find the correct row.

  6. Click on $metadata, then click the Preview tab.

    This will show you the data coming from the server to the browser. If you see this, the OData request is working. You are ready to move on to the next step of the tutorial.

Expand the nodes <edmx:Edmc>, <edmx: DataServices> and the first <Schema> node in the Chrome Network trace.

Which entity types do you find in the network trace after expanding the mentioned nodes?


  • Missing a file? If the list of files doesn’t match the picture, you may have used the wrong template when you created the project. Delete the project, and start the Create a new project tutorial again.

  • $metadata file not listed? This means one of the files in your project is incorrect. Check the files, and make sure no red X marks appear in the left hand column. These indicate a problem with the file syntax. Check the pictures carefully.

  • The Northwind system does not appear in the drop down box. This can happen when the Web IDE is “out of sync” with the server. Reload the Web IDE (by clicking the reload button in your browser). You will come back to the same place, and you can start the steps to create a new OData service again.

  • Don’t forget to save your files! If a file name has a * next to it, the file isn’t saved.
