SAP C_FIORD_2502 - SAP Certified Associate - SAP Fiori Application Developer

SAP offersmultiple extension mechanisms:

Adaptation Project: customizes standard apps without copying code.

View Extensions: via manifest.json to inject custom UI at extension points.

Controller Hooks and Property Overridesfor fine-grained control.

SAP Fiori Extensibility Guide:

“Adaptation projects allow for UI and logic customization using SAP Business Application Studio.”

Changing runtime libraries or merging data at runtime are neither recommended nor supported directly.

Hook methodsare custom logic injection points:

Add conditionals (if (this.extHookFunction) this.extHookFunction();)

Identify extension points in the controller

Provide a placeholder for custom logic, typically in a utility/helper file.

SAP Extension Practices:

“To use hook methods, define optional logic spots and allow override in custom layer.”

Modifying bootstrap is unrelated. Function names do not need special reservations—convention suffices.

MVCarchitecture separates concerns:

Modelhandles data.

Viewdisplays data.

Controllerhandles logic.

Advantages:

Views can be changedindependently from business logic (Controller).

Multipleviewscan present the same model data differently.

SAP MVC Documentation:

“MVC enables separation of concerns, easier debugging, and reusability of components.”

Quick coding is not inherently a feature of MVC, and transport independence is handled via SAP tooling, not MVC itself.

In ahub deployment:

UI5 app code (HTML/CSS/JS) is deployed onSAP Front-End Server (FES).

Business logic (OData services) remains onBack-End Server (BES).

SAP Fiori Deployment Guide:

“FES hosts the UI components and handles UI5 resource loading. BES contains the application data logic.”

Web Dispatcher only routes traffic. XS Engine is for HANA-native apps.

Given the hierarchical structure, where regions is an array, and companies is a sub-array under region[0], correct access is:

/regions/0/companies: path to company list in first region (Americas).

name and city are properties of each company.

SAPUI5 Model Binding Guide:

“To bind list data in nested arrays, use full path access like /parent/0/child.”

QUnitfollows theAAApattern:

Arrange: Prepare test data/setup.

Act: Perform the operation.

Assert: Validate the result.

SAP Testing Guidelines:

“The Arrange-Act-Assert (AAA) pattern is fundamental to unit testing logic with QUnit.”

B is the pattern for OPA5 (behavioral testing), not QUnit.

TheAnalytical List Page (ALP)is ideal for applications requiring:

Charts

Visual filters

SAPUI5 supports three maindata binding modes:

One-way: Data flows from model to view.

Two-way: Data syncs both directions (used in forms).

One-time: Data is injected once and not updated.

SAPUI5 Developer Guide:

“Binding modes define how data is synchronized between the model and the view. The supported modes are: OneWay, TwoWay, OneTime.”

Three-way and resource-model binding are invalid or unrelated to binding modes.

Tiles are linked viaTarget Mappings, which define:

Semantic object + Actioncombination.

This routing determines what app or view is launched.

SAP Fiori Launchpad Configuration Guide:

“Target mappings define navigation logic using semantic object/action. Tiles use these to determine routing targets.”

Semantic object alone is not actionable.
