Explanation
The SAP Fiori launchpad is a role-based, personalized, and real-time access point for SAP applications and services. Some personalization options of the SAP Fiori launchpad are:
Add new tile groups, which are collections of tiles that represent different applications or tasks. You can create your own tile groups and arrange them according to your preferences.
Add tiles to existing tile groups, which means that you can add more applications or tasks to the tile groups that are already available on your launchpad. You can also remove tiles from tile groups or move them to different tile groups. References: SAP S/4HANA Sourcing and Procurement | SAP Learning, Course S4500, Unit 1, Lesson 1.
