Log into your SAP Cloud Platform account and open SAP Web IDE in a Google Chrome browser.

Open the northwind project folder and then the view folder. Right-click on Detail.view.xml and select Open With > Layout Editor (you must use Google Chrome to open the Layout Editor).

When the Layout Editor opens, click on the Supplier icon. The Properties and Data pane will open.

In another browser tab, open the SAPUI5 Icon Explorer. The Icon Explorer shows all of the icons built into the SAPUI5 library.

Enter supplier into the search field, and click on the supplier item in the list. The supplier icon is shown in the various UI5 controls.

To change the current icon in your app, switch back to the Web IDE tab, and enter sap-icon://supplier in the Icon field. If you tab out of the Icon field, the icon will update in the Layout Editor view.

In SAPUI5, a tab is called an IconTabFilter. To add one to your app, click on Container in the palette pane. Click on the Icon Tab Filter, then drag and drop it next to the Supplier tab.

Depending on the path you drag, the new tab may snap to the first (left) spot. You can drag it left and right to place it on the right of the Supplier IconTabFilter before letting the mouse button up. You can also release the mouse button to place it where it snaps to first, then click and drag it to the position you want.

With the new Icon Tab Filter selected, make the following changes in the Properties and Data pane and save your changes.

• Icon: sap-icon://product
• Text: Details
• Count: < delete the 10 >
• Icon Color: Default

Content for a new tab is displayed in a view fragment file.

To create a new fragment file, right-click on the view folder, and select New > File.

Enter ProductDetailInfoForm.fragment.xml for the new file name and click OK.

The new file will open in the editor. Copy the text below, paste it into the new file, right-click in the editor and select Beautify (which will re-indent the XML file), then save your changes.

<core:FragmentDefinition xmlns:core="sap.ui.core" xmlns:f="sap.ui.layout.form" xmlns:l="sap.ui.layout" xmlns="sap.m">
<l:Grid defaultSpan="L12 M12 S12" id="productFragment" width="auto">
<l:content>
<f:SimpleForm columnsL="1" columnsM="1" editable="false" emptySpanL="4" emptySpanM="4" labelSpanL="3" labelSpanM="3"
layout="ResponsiveGridLayout" maxContainerCols="2" minWidth="1024" title="{i18n>tab_product_sub_title}">
<f:content>
<Label text="{i18n>label_CategoryID}"/>
<Text text="{CategoryID}"/>
<Label text="{i18n>label_ReorderLevel}"/>
<Text text="{ReorderLevel}"/>
<Label text="{i18n>label_Discontinued}"/>
<Text text="{Discontinued}"/>
</f:content>
</f:SimpleForm>
</l:content>
</l:Grid>
</core:FragmentDefinition>

In addition to the standard XML wrapper, there are a few key items to call out in the source above:

• In the Grid element, the id is set to productFragment. This allows you to programmatically refer to the grid in the future if needed
• In the SimpleForm element, the title is set to a string in messageBundle.properties. You will add that entry in the next step
• In the f:content element, three additional fields from the Products collection are added (Label and the string) The label strings will be added next.

Open messageBundle.properties and replace all of the content of the file with the lines below. These are the strings for the new Product tab, as well as the Supplier tab (which you will edit next).

masterTitle=Products
detailTitle=Product Inventory Details
notFoundTitle=Not Found
notFoundText=The requested resource was not found
masterListNoDataText=No entities
masterSearchPlaceholder=Search
masterSearchTooltip=Search for product name
currencySymbol=€
label_ProductID=Product ID
label_UnitsInStock=Units In Stock
label_UnitsOnOrder=Units On Order
label_CategoryID=Category ID
label_ReorderLevel=Product Reorder Level
label_Discontinued=Discontinued status
label_SupplierID=Supplier ID
label_CompanyName=Company Name
label_ContactName=Contact Name
label_ContactTitle=Contact Title
label_Address=Address
label_City=City
label_PostalCode=Postal Code
label_Country=Country
label_Region=Region
label_Phone=Phone
label_Fax=Fax
label_HomePage=Home page
tab_supplier_short_title=Supplier
tab_supplier_sub_title=Supplier Details
tab_product_short_title=Product
tab_product_sub_title=Product Details

Your messageBundle.properties file should look like this now.:

Open DetailInfoForm.fragment.xml (which is the fragment for the Supplier tab). In the f:SimpleForm element, replace the title="Supplier" attribute with title="{i18n>tab_supplier_sub_title}" and save your change. Be sure to keep the double quotes. This replaces the string inserted by the template with a reference to one in the messageBundle.properties file.

The Web IDE template inserted three of the fields in the Suppliers Collection (which is linked to the Product Collection). To add in all of the fields available, open DetailInfoForm.fragment.xml, and replace all of the content within the <f:content> element with the source below, Beautify and save your edits.

<Label text="{i18n>label_SupplierID}"/>
<Text text="{SupplierID}"/>
<Label text="{i18n>label_CompanyName}"/>
<Text text="{CompanyName}"/>
<Label text="{i18n>label_ContactName}"/>
<Text text="{ContactName}"/>
<Label text="{i18n>label_ContactTitle}"/>
<Text text="{ContactTitle}"/>
<Label text="{i18n>label_Address}"/>
<Text text="{Address}"/>
<Label text="{i18n>label_City}"/>
<Text text="{City}"/>
<Label text="{i18n>label_PostalCode}"/>
<Text text="{PostalCode}"/>
<Label text="{i18n>label_Country}"/>
<Text text="{Country}"/>
<Label text="{i18n>label_Region}"/>
<Text text="{Region}"/>
<Label text="{i18n>label_Phone}"/>
<Text text="{Phone}"/>
<Label text="{i18n>label_Fax}"/>
<Text text="{Fax}"/>
<Label text="{i18n>label_HomePage}"/>
<Text text="{HomePage}"/>

Your DetailInfoForm.fragment.xml file should look like this now:

The last step is to add a content element to link the new fragment file to the Details Icon Tab Filter. Open Detail.view.xml, replace the text within the items element with the text below, Beautify and save your changes.

<IconTabFilter icon="sap-icon://supplier" key="Supplier" text="{i18n>tab_supplier_short_title}">
<content>
<core:Fragment fragmentName="com.test.northwind.view.DetailInfoForm" type="XML"/>
</content>
</IconTabFilter>
<IconTabFilter count="" icon="sap-icon://product" iconColor="Default" id="__filter3"  text="{i18n>tab_product_short_title}">
<content>
<core:Fragment fragmentName="com.test.northwind.view.ProductDetailInfoForm" type="XML"/>
</content>
</IconTabFilter>

The XML you pasted in did a few things:
- Changed the label on the Supplier tab to a string in the messageBundle.properties file (but otherwise that IconTabFilter tag was unchanged)
- Changed the Product IconTabFilter from a self-closing element to a multi-line element (this is necessary to add in the content element) and set the label string
- Added a content element for the Product tab with a reference to the new fragment you created

Save your changes and reload the preview tab or run the app. Remember, you may need to do a hard reload or clear the cache to see your changes. When the app loads, you will see the additional fields on the Supplier tab. Click on the Product tab to see the fields there.

You can now re-deploy the app to SAP Cloud Platform so you will be able to see your changes on your mobile device.
