Fiori 403 decision tree

Guided questions to the likely cause category of a Fiori “not authorized” error — and what evidence to collect.

Answer a few questions. The tree narrows the problem to a likely cause category and tells you which evidence confirms or rules it out. It does not diagnose your system — the Fiori 403 Root-Cause Doctor does that from the evidence.

Question 1

Where do you see the problem?
