Technical questions for safer SAP decisions.

The most common mistakes are starting implementation without an architecture blueprint, treating integrations as a later detail, keeping customizations without rationalization, overlooking data and security, failing to define an extension strategy, skipping governance and leaving critical decisions without clear ownership.

Start with an end-to-end integration map, API standards, clear contracts, consistent authentication, observability, versioning and ownership. Architecture must account for the lifecycle, not only the flow that works at go-live.

ABAP Cloud supports clean core principles, reduces modification dependencies and creates a more sustainable foundation for extensions. It should be part of an extensibility strategy that also considers CAP, UI5, BTP and product lifecycle.

Define principles, roles, decision criteria, review forums and an approval flow proportional to risk. An effective Architecture Review Board documents decisions and supports squads without unnecessary bureaucracy.

A useful blueprint connects business goals to current and future architecture, covering domains, integrations, data, extensions, security, risks, open decisions, roadmap and governance criteria.

Before choosing brownfield or greenfield, assess processes, customizations, data, integrations, dependencies and change capacity. An independent assessment turns uncertainty into sequenced, verifiable decisions.

The architecture must combine mobile experience, offline synchronization, asset model, EAM/PM integration, BTP extensions, device security and field operations. The design must reflect real connectivity and team processes.
