Use SAP Fiori tools to provide additional functionality to your List Report Object Page app.

You will learn

  • How to use Guided Development in SAP Fiori tools to add functionality
  • How to use the Service Modeler to visualize OData services and the associated annotations in your apps
  • How to use XML Annotation Language Server to define annotations in the code editor

Prerequisites


Step 1: Add Export to Excel button to table

When developing an application, you may know that end users require certain functionality but not be sure how to implement it. The Guided Development extension provides access to how-to guides and tutorials that can help you add a feature to your SAP Fiori elements application.

You can read through the steps required to implement a feature and then either apply the generated code to make the changes to the project or copy the code snippet to your clipboard and make the changes yourself. To begin this tutorial, you will add Export to Excel functionality to your app.

  1. To begin, open the Command Palette using CMD/CTRL + Shift + P and type: SAP Fiori tools: Open Guided Development

    VSCode Open Guided Development

    If this is your first project, you should now see Guided Development with a list of guides grouped together by the page type. If you have other projects available in Visual Studio Code, select your tutorial project to access Guided Development.

  2. Once the Guided Development tab opens, type export in the search field at the top right of the screen. Click List Report Page | Enable table data export to expand the guide.

    Export to Excel

    To understand what the feature does, you can read the description. To implement this functionality, you are going to use the code snippet generated by Guided Development.

  3. To get started, select ListReport_SEPMRA_C_PD_Product from the Page dropdown and click Apply. Guided Development will go to the respective page configuration file and apply the changes.

    Apply Guided Development

    The ListReport_SEPMRA_C_PD_product.json file will open and the code that has been inserted will be highlighted. Save this file using File | Save or CMD/Ctrl + S.

    Configure Guided Development
  4. You can now close the ListReport_SEPMRA_C_PD_product.json and Guided Development tabs.

Switch back to the app preview. You can see that it has been refreshed and the Export to Excel button is now shown in runtime.

Step 2: Enable multiple selection in table

Next, you will implement multiple selection for the table so that your end users can select multiple rows in the list at once. Once again, you will do this with Guided Development.

  1. Use the Command Palette to open the Guided Development tool again.

  2. Using the search box at the top right of the screen, type multi and expand List Report Page | Enable multiple selection in tables, and then click the guide title to expand the guide.

    Guided Development Multiple Selection

    To understand what the feature does, you can read the description. To implement this functionality, you are going to use the code snippet generated by Guided Development.

  3. To generate the code snippet, ensure that ListReport_SEPMRA_C_PD_Product is selected and click Apply.

    Just like the previous step, Guided Development will go to the page configuration file and apply the changes.

  4. The ListReport_SEPMRA_C_PD_product.json will once again open to the side, with the new code inserted and highlighted. Save the file and close both tabs.

The app preview will once again refresh and display both the multi-select boxes, as well as the Export to Excel button.

Step 3: Copy backend annotation visually to local annotation file

This app features a target entity type that has already been pre-configured with the UI.SelectionFields annotation term. This is what provides the filters above the list in your app preview. This next step involves adding a new filter for Product Name, using the Service Modeler in SAP Fiori tools to copy the already existing backend annotation term and add a new field.

The Service Modeler is a graphical tool that provides a visualization of an OData service, including its backend and local annotations. The Service Modeler helps you easily find entities or projections and their associated annotations.

  1. To access the Service Modeler, launch the Visual Studio Code Command Palette by pressing CMD/Ctrl + Shift + P and then typing SAP Fiori tools - Service Modeler: Open Service Modeler. The Service Modeler will open in a list view mode, listing all the projections (e.g., entity types) present in the underlying OData service. Some entries feature an @ icon, which signifies that there are annotations attached to those targets.

  2. For the projection SEPMRA_PROD_MAN.SEPMRA_C_PD_ProductType, click on the @ icon to view all the annotation for SEPMRA_PROD_MAN.SEPMRA_C_PD_ProductType.

    Open Service Modeler

    This opens Annotation List View, where you can see that for target SEPMRA_PROD_MAN.SEPMRA_C_PD_ProductType, all the annotation terms come from sources such as the local annotation file annotation.xml, the backend annotation file SEPMRA_PROD_MAN_ANNO_MDL.xml, and metadata.xml. Since the requirement is to add a new filter, you have to modify UI.SelectionFields.

  3. Copy UI.SelectionFields from the backend SEPMRA_PROD_MAN_ANNO_MDL.xml source to the local annotation.xml source by clicking the Copy icon next to UI.SelectionFields under SEPMRA_PROD_MAN_ANNO_MDL.xml.

    Copy with Service Modeler

    UI.SelectionFields under SEPMRA_PROD_MAN_ANNO_MDL.xml has now been formatted with a strike through, giving you a visual indication that UI.SelectionsFields at runtime will be picked up from the local annotation file.

  4. Now that you have successfully copied backend UI.SelectionFields to the local annotation file, click the Show in source button next to UI.SelectionFields, under annotation.xml. This takes you to the local annotation.xml file, with the exact code to be changed highlighted.

    Go To Source Code
  5. Close the Service Modeler tab.

Step 4: Edit UI.SelectionFields in code editor

With UI.SelectionFields in the local annotation file, you now need to edit it so that new filter of Product Name shows up in your SAP Fiori elements application. To do so, you will use the XML Annotation Language Server, which provides features that assist with defining annotations in the code editor.

The features used in this tutorial include:

  • Code Completion, which provides a list of suggestions based on the project metadata and OData vocabularies;
  • Micro-Snippets, which are generic snippets that add bigger blocks of code patterns, such as Annotations and Annotation and Record.

These features help you to quickly and consistently generate code for your projects.

  1. To start, ensure that local annotation file annotation.xml is open. If its closed, navigate to myfioriapp(or your project name)->webapp->annotations->annotation.xml in the project explorer.

  2. For the SAP.SEPMRA_C_PD_ProductType annotation term UI.SelectionFields, place your cursor after the line below and press Enter.

    Annotation Cursor
  3. In your new line, trigger the code completion by pressing CMD/Ctrl + Space, which displays a list of suggested values.

    Select <PropertyPath> and accept it by pressing Enter or clicking with your mouse. Your cursor will be between the tags <PropertyPath> and </PropertyPath>.

    Press CMD/Ctrl + Space again to see the next list of options (the properties of target SEPMRA_C_PD_ProductType). Your desired value is Name.

    Use the up/down arrows on your keyboard or your mouse to navigate to it in the list and then press Enter or select it with your mouse.

    Select Name
  4. Save your annotation.xml file and then check your running application. The new Product Name filter should now be in your app.

At this point, you should have a List Report Object Page with Export to Excel and multi-select functionality, in addition to the ability to filter by product name.

Good job! In the next tutorial, you will configure the object pages that users can access from this list.
