Step 2 : Importing Fiori app source code into Eclipse:

Now, you will import the source code into Eclipse and modify the SAP Fiori app with SAPUI5 controls and libraries:

1. Start Eclipse and go to File → New → Project
2. Choose SAPUI5 Application Development → Application Project and click “Next”

7. Click Yes to All when prompted to overwrite the files.You have successfully imported the source code into the Eclipse environment.

Step 3 : Modifying a SAP Fiori App source code

You may want to add another field to the details view of a purchase order. Adding a field only requires making changes to a view, not a controller.

To add a field to the UI you have to make changes to “PurchaseOrderInformation.view.html”

1. Open PurchaseOrderInformation.view.HTML in Eclipse.In this example, you will be adding the Purchasing Group field and it will be placed above the Purchase Order ID field. Within the PurchaseOrderInformationview, copy the source code that yields the Purchase Order ID field and inserts it, so that it produces another field. As of now, the Purchase Order ID field appears twice.

2. Change the newly inserted code, so that it represents the Purchasing Group instead of the Purchase Order ID:

a. Change the label text to Purchasing Group in the appropriate logon language. As this is a translation relevant task, you have to create a new translation entry in the appropriate resource files later (i18n file). For now, change the data-text attribute of sap.m.Labelto{i18n>view.PurchaseOrder.zPurchasingGroup}.

b. Change the text view, so that the content is bound to the field in your data model that contains the Purchase Group. Change the data-text attribute of sap.m.Text to {ZPurchasingGroup}.

3. As the Purchasing Group term is translatable, it has to be added to the internationalization (i18n) resource files, instead of being written directly in the view’s source code. Add the view.PurchaseOrder.zPurchasingGroup a term with the appropriate translation to all i18n resource files. These files can be viewed under the i18n folder.Now, test it locally to view the changes.

Step 4 : Uploading the customized SAP Fiori App code

You can upload the customized source code to the server.

1. Run the SE38 transaction.

2. Type /UI5/UI5_REPOSITORY_LOAD in the Program field and click Run (F8) to run theSAPUI5 repository synchronization program.

7. Before the upload process begins, you will be asked for some additional parameters, such as transport request and package name. Provide the appropriate values and click Confirm.You have successfully uploaded the code to the server.

Step 5 : Testing your application

1. Run the SE80 transaction and navigate to the package specified during the upload process.

2. Find the application that you uploaded in the repository browser. In the object tree, you will find it under BSP Library >BSP Application>(Name of your SAPUI5 application).
