Dr. Sarah Chen breaks down what you need to know
In 16 years of untangling SAP authorization failures, I’ve learned one hard truth: migration projects treat security as a post-go-live checkbox. That’s why help desks melt down in week one. The recent industry conversation about moving to S/4HANA being the perfect time to clean up access is exactly right — but only if you treat it as a deliberate workstream, not a byproduct of technical conversion.
The Real Story
S/4HANA migrations, especially brownfield conversions, often carry forward legacy authorization debt. Roles built years ago for ECC get copied, adjusted, and layered with new Fiori catalogs. The result: orphaned authorizations, missing checks, and users who either have too much or too little access.
The technical conversion itself doesn’t fix security. It just recompiles the same mess into a new architecture. What does change is the opportunity. During migration you’re already touching roles, users, and transport paths. That’s exactly when you should clean up.
Two transaction codes matter more than most during this period:
- SU53 — the immediate diagnostic after an end user hits an authorization error. It shows the exact failed authorization object, values, and missing check.
- ST01 — the trace tool that captures authorization checks in real time for complex or intermittent failures.
I’ve watched Basis teams skip SU53 and instead ask users to “try again.” That’s wasted time. SU53 gives you the failure directly. ST01 gives you the trail when SU53 isn
