Fiori MCP-First Development

Before writing, modifying, debugging, or fixing CDS annotations, Fiori Elements page configuration, or manifest.json, you MUST query the Fiori MCP server and apply its guidance.

Tools

Use mcp__fiori__* tools — primarily mcp__fiori__search_docs, mcp__fiori__list_functionality, mcp__fiori__get_functionality_details, and mcp__fiori__execute_functionality.

Workflow

1. Query before coding — call mcp__fiori__search_docs for annotation patterns, floorplan config, or manifest structure
2. Trust MCP over training knowledge — if guidance conflicts with what you know, follow MCP
3. Use Fiori MCP tooling for modifications — before manually editing manifest.json or annotations, check if mcp__fiori__list_functionality provides an automated function
4. Prefer the simplest pattern when MCP returns multiple valid approaches

Scope

This skill covers:

• CDS annotations: @UI, @Common, @Capabilities, @Communication
• Fiori Elements floorplans: List Report, Object Page, Analytical List Page
• manifest.json configuration: routing, data sources, control configuration
• Custom actions in manifest (controlConfiguration.actions)

Fiori Elements App Rules

When creating or modifying SAP Fiori Elements applications:

• The application typically starts with a List Report page showing the base entity in a table. Row details are shown in an ObjectPage based on the same entity.
• An ObjectPage can contain table sections based on to-many associations. Row details in a table section can open another ObjectPage based on the association's target entity.
• The data model must have one main entity with navigation properties to related entities.
• Each property must have a proper datatype.
• For all entities, provide primary keys of type UUID.
• When creating sample data in CSV files, all primary keys and foreign keys MUST be in UUID format (e.g., 550e8400-e29b-41d4-a716-446655440001).
• When modifying the application (e.g., adding columns), do not use screen personalization — modify the project code. Always check whether mcp__fiori__list_functionality provides a suitable function first.
• When previewing, use the most specific npm run watch-* script for the app in package.json.
