What is SAP Fiori Catalogs, Groups, spaces & Pages

Catalogs

• Purpose: 

  Catalogs are containers for Fiori app tiles. They are technical or business-oriented and are used to manage and organize tiles. 
• Types: 

  They can be technical (containing many tiles) or business-oriented (used for specific business roles). 
• Assignment: 

  Business catalogs are assigned to business roles, which determines which apps a user can see. 

Groups

• Purpose: Historically, groups were used to organize tiles for users on the Fiori launchpad. 
• Status: SAP is phasing out groups in favor of spaces and pages. 
• Content: They contained tiles that were available to the user. 

Spaces

• Purpose: Spaces are the modern, primary way to organize content on the Fiori launchpad, replacing groups. 
• Structure: A space is a container that holds one or more pages. 
• Assignment: Spaces are assigned to business roles. 
• User Experience: They offer a more focused "day-in-the-life" approach compared to groups, providing a cleaner, simpler view of essential starting points. 

Pages

• Purpose: Pages are individual screens within a space that display apps as tiles. 
• Structure: Pages can have single or multiple sections that further organize tiles. 
• Content: They are created from catalogs and contain a collection of apps for a specific business purpose. 
• Assignment: Pages are assigned to spaces.
