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.
NHIMG editorial — based on content published by Pathlock: SAP GUI vs Fiori and the evolution of enterprise user interfaces
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.

Pathlock's full article covers the technical and design detail this post intentionally leaves for the source:
- The SAP GUI, Web Dynpro, SAPUI5, and Fiori progression with architecture-specific examples.
- The role of OData, launchpad catalogs, and backend authorization checks in app access.
- Practical UX trade-offs between dense power-user workflows and mobile-friendly end-user flows.
- The future direction of SAP BTP extensions, low-code development, and AI-driven interfaces.

Fiori turns SAP access governance from transaction control into entitlement composition. SAP GUI concentrated access decisions around backend transactions, while Fiori distributes them across tiles, catalogs, OData services, and backend authorization objects. That changes the governance problem from granting access to a function into proving that the whole access chain is aligned. Practitioners should treat the launchpad as an entitlement assembly point, not a cosmetic layer.
A few things that frame the scale:
- The average estimated time to remediate a leaked secret is 27 days, despite 75% of organisations expressing strong confidence in their secrets management capabilities, according to The State of Secrets in AppSec.
- Organisations maintain an average of 6 distinct secrets manager instances, creating fragmentation that undermines centralised control, according to The State of Secrets in AppSec.
A question worth separating out:
Q: Should organisations keep SAP GUI access after moving to Fiori?
A: Yes, where expert workflows, custom transactions, or legacy dependencies still require it. The mistake is treating GUI as automatically obsolete and leaving it unmanaged. If it remains in production, it should be narrowly scoped, recertified, and linked to the same governance process as Fiori access.
