SAP Fiori catalogsare groups of Fiori apps organized by business roles. They help users find the applications they need in theSAP Fiori Launchpad. While catalogs show which apps users can access, they do not control how these apps are displayed – that’s handled byspaces and pages. Catalogs can include tiles, target mappings, and links to different SAP applications, such as classic SAP GUI transactions, Web Dynpro apps, and Fiori apps. Administrators create and assign these catalogs using the SAP Fiori Launchpad Designer or SAP Fiori Launchpad Content Manager. This process ensures that users see only the applications that match their roles and business needs. Good catalog management enhances the user experience, boosts security, and increases system efficiency by making it easier to access the right tools.
