SAP S/4HANA, SAP’s next-generation ERP suite, offers a powerful and intelligent platform for digital transformation. SAP-UI5, the UI development toolkit for building responsive web applications, is often the front-end technology of choice for extending and customizing SAP S/4HANA user experiences.
Integrating SAP-UI5 applications with SAP S/4HANA allows developers to build modern, user-friendly interfaces that tap directly into enterprise business processes and data. This article covers key concepts, approaches, and best practices for integrating SAP-UI5 apps with SAP S/4HANA systems.
SAP S/4HANA exposes business data and logic through OData services via the SAP Gateway. These services form the backbone of SAP-UI5 integration.
Steps to consume OData in UI5:
manifest.json model entry to point to the OData endpoint.sap.ui.model.odata.v2.ODataModel or sap.ui.model.odata.v4.ODataModel for data binding.Fiori Elements enable rapid app development by generating UI5 apps from annotations on OData services without manual UI coding.
SAP S/4HANA also exposes RESTful APIs and SOAP services. UI5 apps can integrate via these APIs for specific use cases requiring direct protocol control.
SEGW) or SAP API Business Hub.For cloud-based UI5 apps (e.g., on SAP BTP), define destinations in SAP Cloud Platform Cockpit to connect securely to S/4HANA on-premise or cloud.
manifest.json, define the OData model:"sap.ui5": {
"models": {
"": {
"dataSource": "S4HANA_ODATA",
"settings": {
"useBatch": true,
"defaultBindingMode": "TwoWay"
},
"type": "sap.ui.model.odata.v2.ODataModel"
}
},
"dataSources": {
"S4HANA_ODATA": {
"uri": "/sap/opu/odata/sap/API_SALES_ORDER_SRV/",
"type": "OData",
"settings": {
"odataVersion": "2.0"
}
}
}
}
Example:
<Table items="{/SalesOrderSet}">
<columns>
<Column><Text text="Order ID" /></Column>
<Column><Text text="Customer" /></Column>
</columns>
<items>
<ColumnListItem>
<cells>
<Text text="{SalesOrderID}" />
<Text text="{CustomerName}" />
</cells>
</ColumnListItem>
</items>
</Table>
$select, $filter, and $expand query options to minimize payload./IWFND/GW_CLIENT): Test OData services in S/4HANA backend.Integrating SAP-UI5 with SAP S/4HANA unlocks the full potential of building modern, user-centric enterprise applications. By leveraging OData services, Fiori Elements, and SAP’s design principles, developers can create seamless, efficient, and scalable front-end solutions that extend the capabilities of S/4HANA.
Proper configuration, secure connectivity, and adherence to best practices ensure a successful integration journey that drives business value and improves user satisfaction.
