Deliverables, Ownership & Candidate Profile

Key Deliverables

SAP integration architecture and interface inventory.
Interface design documents and API / IDoc / OData mapping specifications.
SAP configuration, technical developments, and middleware integration flows.
Security and connectivity design inputs.
Unit test results, SIT evidence, and UAT defect-resolution support.
Production deployment, cutover, and stabilization support.
Monitoring, support, and operational handover documentation.
Role Ownership

Own the SAP side of the integration workstream from design through deployment.
Act as the technical bridge between external product teams, SAP functional teams, and enterprise integration teams.
Challenge requirements where standard SAP integration services can simplify the solution.
Ensure interfaces are scalable, secure, supportable, and aligned with target architecture.

Ideal Candidate

The ideal candidate is a hands-on SAP integration specialist who can independently analyze procurement scenarios, identify the correct SAP integration mechanism, design end-to-end interfaces, and work directly with external product teams. The consultant should combine strong SAP technical integration skills with sufficient MM/P2P functional understanding to own the solution rather than operate only as a middleware developer.
