SAP Fiori Launchpad
The SAP Fiori launchpad is a shell that hosts SAP Fiori apps and provides services such as navigation, personalization, embedded support, and application configuration.
The launchpad is the entry point to SAP Fiori apps on mobile and desktop devices. The SAP Fiori launchpad home page is the first page users see after signing in. The launchpad home page displays tiles and links, allowing users to launch apps. Tiles are a visual representation of an app. Each tile represents a business application that the user can launch.

The tiles/apps displayed to users on the SAP Fiori launchpad are organized using catalogs and groups.
A catalog is a set of tiles that you want to make available for one role. These catalogs are assigned to business roles. Depending on the role and the catalogs assigned to the role, users can browse through the catalogs and choose the tiles.
Groups define the grouping, sort order, and general appearance (tile or link) of apps that are initially displayed on the SAP Fiori launchpad home page for a user. Users can personalize the Entry Fiori Page by adding or removing applications to predefined or self-defined groups.

The SAP Fiori launchpad layout can be structured by groups or by spaces and pages.
A space serves as an entry point for a business role and shows information and functions that are assigned to that business role. A space is represented as a navigation item in the top-level navigation. It consists of one or multiple pages that further structure the content of a space.

A page is part of a space with one or multiple pages. Multiple pages allow users to structure the space into numerous self-contained work contexts. Business roles with fewer apps may use one page per space, whereas those with more apps may use multiple pages. A page consists of sections that are used to structure the content further.
A section structures the content of a page semantically. A section consists of tiles that visualize the content of a space. A section title is optional.
Users can switch between both layouts with the user actions menu.
SAP Fiori Library

The SAP Fiori Apps Reference Library is a comprehensive library of all relevant SAP content for the SAP Fiori launchpad. All available apps can be explored using the SAP Fiori Apps Reference Library. See https://www.sap.com/fiori-apps-library.
SAP Fiori apps can be categorized by line of business, industry, user role, and technical foundation.
Using the library, you can:
- Find filters such as Application Type and Product Version to help select the sets of apps needed.
- Find key information for each app, including all the technical data required for installation and configuration

In the details for an SAP Fiori app, you should first set the product suite followed by the release at the top of the page. Although an app is available in several products and releases, their implementation may differ. The header information, product features, implementation information, and related apps change depending on the selected product and release.
Catalogs are the basis of the SAP Fiori content in the SAP Fiori launchpad. Technical catalogs define apps per solution area, whereas business catalogs reference these apps per user duty. Groups, spaces, and pages reference tiles and links per business topic from business catalogs. Business catalogs, groups, and spaces can then be assigned to users via business roles.
