Migrate to S/4HANA.
Catch API regressions before every cutover.
Keploy records live integration traffic on your middleware before cutover and replays it against S/4HANA, catching API contract regressions before they reach production without writing a single test.

Why SAP migrations fail after go-live.
ECC to S/4HANA migrations fail silently. Integrations break without errors, dependencies go undocumented, and regression costs compound across every cutover wave.
Migration breaks integrations.
SAP API and integration contracts change silently in S/4HANA. Downstream services consume stale field mappings with no runtime errors and no data corruption signals.

Dependency management and setup complexity.
API integrations, middleware connections, and service consumers accumulate silently over years. S/4HANA restructures the foundation beneath all of them, and no native SAP tool maps which external systems are calling in.

Interface dependencies per landscape
Typical RICEFW range per SAP landscape. Large enterprise landscapes exceed 200.
Increased test infrastructure cost.
Authoring manual stubs, replicating SAP landscapes and rewriting regression suites from scratch every wave consumes over 60% of SAP transformation effort on QA alone, with zero reuse across phases.

Coverage for every cutover wave.
Record integration traffic before cutover, replay it against S/4HANA after each wave, and catch API contract regressions before they reach production.
Keploy records OData, SOAP, SAP Gateway and REST calls on your integration middleware.
Sits on your integration middleware and captures OData, SOAP, REST and SAP Gateway traffic between your services and S/4HANA. Complete request and response payloads. No changes to SAP configuration, ABAP code, or system parameters.

Keploy replays against S/4HANA. Catches API contract regressions.
After each cutover wave, Keploy replays the full pre-migration corpus against your live S/4HANA target. Non-SAP downstream dependencies are served from captured snapshots. Any API contract changes S/4HANA introduces are caught in the field-level diff before hypercare opens.

Keploy auto-generates SAP regression coverage from real traffic.
Keploy auto-generates regression coverage from real production traffic and detects API contract drift after each cutover wave. When a replay surfaces a regression, the team decides whether to re-record the affected interactions to refresh the baseline with no manual stub rewriting required.
