Five pages, about 21 minutes in total.

- S/4HANA 2025 Cutover Validation for SAP Utilities and FI-CA: What to Test Separately — 3 min. What your test scripts need to cover separately for Utilities before cutover sign-off.
- After Go-Live: Measuring Fiori Adoption and Retiring GUI Fallback Safely — 3 min. How to know when your billing and operations teams have actually adopted the apps you shortlisted, and when GUI fallback can safely come off.
The IS-U catalogue is small and exception-shaped: it clusters around monitoring, outsorts and BPEM clarification cases in meter reading and billing, not around the master-data and processing transactions an IS-U consultant runs most often. Reading this path in order means you scope against that real shape instead of assuming a generic Fiori rollout pattern will cover meter-to-cash the way it covers other lines of business.
The pages in this path draw on the SAP export of September 2026 for product 2025 (Private Cloud): 20 app records sit in the eight IS-U components, and 14 of the 20 carry a supplied transaction code across 9 distinct codes. The snapshot has not been revalidated against the live SAP Fiori Apps Reference Library.
Coming next for this role
Still to come that will extend this path: Utilities transformation, and per-app guides for the Utilities apps.

Frequently asked questions
Should I read the how-to-use guide before this path?
It helps but is not required here. This path assumes you already know how to read the app catalogue tables and callouts; if a callout's meaning is unclear, the how-to-use guide in Start Here explains all four.
Does this path cover FI-CA or Convergent Invoicing apps?
Only where they meet IS-U directly, through the shared transaction lookup and the shared cutover checklist. For Convergent Invoicing scope specifically, use the FI-CA and Convergent Invoicing Consultant reading path.
