SAPUI5 Getting Started (SAP HANA)

This page contains basic knowledge on how to start with SAPUI5 development on SAP HANA development stack and also how the SAPUI5 application looks like.

SAPUI5 Micro Service

SAPUI5 libraries can be used from the public SAPUI5 libraries.

Since SAP HANA 2.0 SPS 03 XS Advanced is capable of providing a micro service itself for local consumption.

A local micro service can be created either in XS Advanced Cockpit at

• HANAExpress -> development space -> Services -> Service Marketplace -> sapui5_sb

or via command line with:

xs create-service sapui5_sb sapui5-1.52 openSAPHANA_00-ui5

The service has to be added in:

Path	File	Function
/	mta.yaml	Create new resource and add it to modules
/web/	xs-app.json	Use replace capability of app router to insert UI5 service URL dynamically
/web/	index.html	Fetch bootstrap from resource by utilizing variable

SAPUI5 App Structure

We create an app odataView. All of its files will be located inside

/web/resources/odataView/

Content:

Relative Path	File	Function
./	index.html	Load SAPUI5 bootstrap Load error handler Load startup.js for session info, unified shell
./	Component.js	Represents the real start of the application Initialize SAPUI5 component Define manifest Create instance of JSON configuration model Load first view
./	manifest.json	Specifies: libraries and versions device types and supported themes root view dependencies odata models text bundles
./i18n/	i18n_en.properties	text bundles for language EN
./view/	App.view.xml	Contains: Shell control and overall flow of the page Fragment for embedded areas
./view/	MRead.fragment.xml	Contains: Input fields Fragment for header area Fragment for item area
./view/	MTableHead.fragment.xml	SmartTable control for display of Purchase Order Header returned by XSODATA service
./view/	MTableItem.fragment.xml	SmartTable control for display of Purchase Order Items
./controller/	App.controller.js	Contains methods: onInit callMultiService: Handles call of odata service to dynamically create columns in table controls callExcel: Calls download of PO data in Excel format
./controller/	Base.controller.js	Base controllers can contain functions and share them to multiple app controllers.
./model/	formatter.js, grouper.js, GroupSortState.js, models.js	Model subdirectory contains reusable functions like formatters

Text Bundles

Text bundles are best located in a subfolder of:

/web/resources/

Contents:

Relative Path	File	Function
./i18n/	messagebundle.properties	Default language message bundle
./i18n/	messagebundle_de.properties	Language DE message bundle

Add code:

/* Language Resource Loader */
jQuery.sap.require("jquery.sap.resources");
var sLocale = sap.ui.getCore().getConfiguration().getLanguage();
var oBundle = jQuery.sap.resources({url: "./i18n/messagebundle.properties", locale: sLocale});

// create the button instance
var myButton = new sap.m.Button("btn");

// set properties, e.g. the text (there is also a shorter way of setting several properties)
// myButton.setText("Hello World!");
myButton.setText(oBundle.getText("helloworld"));
