Developing SAP Fiori App using SAP Fiori Tools in Visual Studio (VS) Code

Hi Everyone,

Hope you have gone through my previous blog on Installing Visual Studio Code and Configuring SAP Extensions in Visual Studio Code

Now let us create our first app using SAP Fiori Tools in Visual Studio (VS) Code.

Once we open the Visual Studio (VS) Code, use Ctrl+Shift+P to launch command palette and search for Application Generator and choose that to create SAP Fiori App.

Now Yeoman Generators will launch as shown below and choose SAP Fiori Tools – Application Generator and click on Next.

Now we need to select template from the available Template Selection (List Report Object Page, Worklist, Analytical List Page, and Overview Page). We will choose List Report Object Page V2 and click on Next.

Now, we have to connect to backend system either by connecting to SAP System or using the OData service or through Metadata document. Here we will go with Connect to an OData Service and click on Next.

Here let us go with Northwind service https://services.odata.org/V2/Northwind/Northwind.svc/.

Provide Northwind service in Odata v2 Service URL, then available entities will be loading in Main Entity, I have choose Products and click on Next.

Now we need to project details like module name, title of your application, namespace for the application, description, and project path. When we choose Yes for Configure advanced options, it will enable UI5 version selection and theme selection of your choice. Click on Next to proceed further.

Now application will be created and opened as below.

Now open New Terminal using Ctrl+Shift+`. Enter the command npm install to install required dependencies.

Once the dependencies got install. Enter the command npm start.

App will open and run on http://localhost:8080/ which will be opened automatically in the default browser as below.

Click on Settings, it will pop up window with available filters as below. Choose “Select All” and click on “Ok”.

Click on Go.

Yeahhhh !!!!!!!!. Finally, we have created our first SAP Fiori Tools App in Visual Studio.

Hope you guys like this blog post.

Hello Nithesh,

i have the same issue.

Because the app try to request the URL: http://localhost:8080/V2/Northwind/Northwind.svc/

I have put the url: https://services.odata.org/V2/Northwind/Northwind.svc/ in the input field.

How i can solve this??

I also couldn't display the UI with npm run command.

What I did was to go on your app folder and right click on it. Then you see preview application start-noflp.

Or simply run the command "npm run start-noflp"

Hi Nitesh,

Will VS Code be the IDE to go and will it be supported long term? Since Eclipse tooling was only supported until version 2019-12.

Hope it will be supported for long term, because SAP Business Application Studio and VS Code playing the same role as Online IDE and Offline IDE

You can provide your ODATA Service in the Service and Entity section which will be accessable in your browser where you are using VS Code

Hi Vijay,

By seeing the error screenshot, as per my understanding NodeJS is not installed correctly. Can you please make sure node path is configured in the environmental variable.

Now, I can run my project in local machine. It seems that the system is operating well however I still got the error as shown in the below image. I am wondering if there is any hidden issue which cause this error. Do you have any idea about this error. Hope you can investigate more on the issue and give me some updates about it.

Hi Manh,

By looking into the screenshot, below are my understandings.

Failed to load resource Component-preload.js- This file will be created automatically in WebIDE, but locally we need to generate it. In general, it is optional. you can follow this blog to create component-preload.js
For i18n related file issues, make sure file path is correct while loading.

Let me know if you still face any issues.

Hi SaiNithesh Gajula

The SAP that we use to develope is internal (Not accessible from the network).

Now, we have a configuration created in the SAP Cloud Connector to be able to work with WebIDE.

How can we work from visual studio code with the configuration of SAP Cloud Connector?

Thanks,

Jose

Once you connect to the VPN, you should able to access it locally in Visual Studio Code.

Hi Nilesh,

Seems like your system cant able to reach the service might be because of proxy. If you are connected to any proxy. Execute the below command in console and try to create the app.

npm config set proxy http://host:port

Hi Nithesh,

Great blog. But one question, how do we set sap-client for Fiori application for testing. Where we have 2 different client for testing and development. Where it should be defined?

Regards,

Irfan G.

Sachin Kulkarni

April 29, 2021 at 11:04 am

Hi Irfan,

Fiori application consumes the service end point i.e. OData service which is configured to talk to a specific client. Hence client configuration doesn't arise at VS configuration level when consuming an OData service.

Alternately if during the creation of the Fiori app via VS, if it is chosen to "Connect to an SAP system", then the configuration provides an option to specify the client if it is ABAP On Premise. Connecting to an ABAP environment on SAP BTP would be driven by service key file.

I hope this information helps.

Hello

Great blog, thank you very much.

I have followed the steps and my App is starting, but it starts not in the Fiori Launchpad. I think i am missing a configuration or something?

I have created an Freestyle SAPUI5 Application.

Any idea what i must configure, that it runs in the Fiori Launchpad environment?

Thanks

Is it to possible to connect to a SAP system configured in SCP/BTP ?

Hi Amel,

Please try if this works. In the template wizard, at the step 'Data Source and Service Selection' the following configuration might enable connection to SAP system over BTP.

Hi SaiNithesh Gajula

Thank you for your great blog! Do you know any VS extensions where I could add Fiori Elements Extensions to my Fiori Elements App? I use the List Report Template, but I need to expand it with a Dialog or Fragment in order to display an PDF Viewer. Currently it is impossible to find some info about this. There are only blogs, docs and tutorials for WebIDE.

Thank you and regards,

Blazenko

If you are using the OData service which requires authentication, definitely it will prompt for credentials for the first time.
