Upgrades: More than what you see
Migrating from ECC to S/4HANA doesn’t end testing challenges—it introduces new ones.
S/4HANA releases occur several times a year, and each update can change interfaces, data structures, and validation logic.
In S/4HANA’s collaborative, role-based model, seemingly isolated changes—such as a Fiori naming update—
can alter how your SAP system behaves end to end across GUI, Fiori, and APIs.
Why Traditional Testing Fails
Traditional testing validates releases in isolation.
But real S/4HANA work happens across GUI, Fiori, and APIs—together.
Limitations of Traditional Testing
Tests separate each release
Only happy paths tested
Interface errors go unnoticed
Reality After Upgrade
Interconnected Fiori/GUI/API
Errors under real use
Critical failures disrupt work
Miss deep bugs
Critical work failures
From Upgrade Risk to Predictable Change
Pain Point
PerfecTwin's approach
Validate integrated workflows across UI and backend
PerfecTwin analyzes differences between S/4HANA releases and focuses testing on areas where interface changes impact real business behavior.
Validate end-to-end workflows spanning GUI, Fiori, and APIs
Expose defects at interface boundaries and transition points
Detect issues caused by renamed apps, fields, and interfaces early
Result
Stable user workflows after upgrades
Integrated validation makes upgrade impact visible before go-live.
Reduced disruption across UI and backend interactions
Early detection of interface-related failures
Predictable user experience after each upgrade
That’s why S/4HANA upgrades demand faster, smarter testing.
