Step 1 of 3

1. Platform and transaction

S/4HANA editionIs the exact target release known?Must the behavior run inside the S/4 transaction?

2. Purpose and interaction

Required outcomePrimary triggerInteraction semanticsMediation, transformation or routing across 2+ systems?

3. Extension constraints

Local UI or key-user adaptation?

Core constraints

Classic extensibilityModification

Released extension point, API or event confirmed for the exact release?

Optional ownership tie-breaker

Leading delivery ownership

Ownership can break a close runtime fit, but it never establishes architecture eligibility.

Practical usage guide

A practical workflow for Clean Core Architecture Advisor

Build one evidence-led SAP extension architecture hypothesis with a primary runtime, component flow, governance gates, one fallback and explicit human confirmation.

1. Prepare

Describe edition, transaction boundary, trigger, interaction and evidence. Example: a local S/4HANA adaptation without an independent process, with extension-point availability unverified.

2. Review

Review the deterministic pattern and runtime recommendation, alternatives, discarded options, questions and gates. Check which conclusions depend on missing release or extension evidence.

3. Apply

This does not verify actual API availability or certify clean core compliance. Confirm released extension points and transaction constraints in the target edition before choosing an implementation.

Verification before operational use

Use a representative case with the inputs needed to reproduce it.
Confirm the result in the authorized target environment when runtime versions, namespaces, extensions, permissions or system configuration can change the outcome.
Record the source, assumptions, tool settings and expected result so another reviewer can reproduce the check and distinguish verified facts from recommendations.
