TL;DR: SAP GUI remains the dense, power-user interface for legacy SAP transactions, while Fiori shifts access toward role-based, browser-friendly apps with tile, OData, and backend authorization layers, according to Pathlock. The governance issue is not just usability but how UI modernization changes role design, entitlement maintenance, and control complexity across mixed SAP environments.

Questions worth separating out
Q: How should security teams govern access across SAP GUI and Fiori at the same time?
A: They should govern the two interfaces as one entitlement system with different entry points.
Q: Why does Fiori increase IAM complexity even though it simplifies the user experience?
A: Fiori simplifies navigation for users, but it adds layers that IAM and IGA teams must manage, including catalogs, services, and backend authorizations.
Q: What breaks when SAP GUI and Fiori roles are not aligned?
A: Users see missing tiles, partial app functions, or overbroad fallback access in the legacy GUI path.
Practitioner guidance
- Map SAP GUI and Fiori entitlements separately Build a crosswalk of GUI transaction codes, Fiori tiles, OData services, and backend authorization objects so access reviews can trace the full path to execution.
- Rationalize hybrid roles before expanding Fiori adoption Identify duplicated or overlapping role patterns across SAP GUI, Web Dynpro, and Fiori, then remove obsolete assignments before adding new catalog-driven access.
- Test business-critical workflows end to end Validate approvals, inventory checks, and administrative tasks in the actual launchpad flow, including missing tile scenarios and backend authorization failures.
