Overview ​

The Cookbook collects task-oriented recipes for everyday abap2UI5 development. Each section focuses on one area of the framework and shows the patterns you reach for most often. Use this page as a map — pick the topic that matches the problem in front of you and jump straight in.

Sections ​

View ​

Build the XML view your app sends to the browser. Covers the basic view definition, nesting views inside other views, and XML templating for repeating structures.

Model ​

Share data between ABAP and the frontend. Explains one-way and two-way binding, expressions and formatters, tables and trees, the device model, and how to deal with the model size limit.

Event, Navigation ​

Understand how a request flows through your app. Covers the lifecycle, backend and frontend events, actions, navigation between apps, and exception handling.

Overlay parts of the view with dialogs and popovers — custom popups, popovers anchored to a control, and the built-in dialogs the framework ships out of the box.

Translation, Messages ​

Communicate with the user. Show message toasts and message boxes, write to the application log, and translate text with i18n.

Browser Interaction ​

Reach into the browser from ABAP — set the tab title, control focus and scrolling, run timers, access the clipboard, work with the URL, and handle the soft keyboard on mobile.

Device Capabilities ​

Read device info and use native hardware: camera, geolocation, barcode scanning, audio, and file upload/download including PDF and spreadsheet generation.

State, Connectivity ​

Manage session and app state across requests and talk to the outside — locking, statefulness, WebSocket, logout, OData, and sharing app state via URL.

More Topics ​

EML/CDS/SQL integration with RAP, recurring patterns and helpers, troubleshooting, and a list of obsolete features kept for reference.
