UI5 Data Binding (OData V4) — Best Practices

Primary reference: https://ui5.sap.com/#/topic/5de13cf4dd1f4a3480f7e2eaaee3f5b8 Accessing data in controller code: https://ui5.sap.com/#/topic/17b30ac2d5914b0891b3b4ef3fc58e90 requestContexts API: https://ui5.sap.com/#/api/sap.ui.model.odata.v4.ODataListBinding#methods/requestContexts Batch control: https://ui5.sap.com/#/topic/74142a38e3d4467c8d6a70b28764048f

Always use the OData V4 model (sap.ui.model.odata.v4.ODataModel) for new SAPUI5 apps with CAP or S/4HANA Cloud — V2 is legacy and loses batch optimisation, side effects, and deep integration with Fiori Elements.
