Project overview

For our client in Frankfurt am Main, we are looking for a Senior SAP Technical Migration Architect ECC / S/4HANA.

Responsibilities

• Examination of an existing SAP data and system model from an ECC environment regarding completeness, correctness, and long-term viability for an S/4HANA transformation.
• Analysis of SAP repository, dictionary, and transport metadata at table and object level, especially for the functional-technical classification of customer-specific developments.
• Validation of whether modeled SAP objects access the correct tables, keys, data sources, and granularities and have been interpreted correctly from a functional perspective.
• Execution or functional assessment of custom code analyses in the context of an S/4HANA migration.
• Evaluation of results from ATC, S/4HANA Readiness Checks, Simplification Item Checks, and related analysis tools, and derivation of concrete action requirements.
• Analysis of the actual usage of customer-specific developments based on usage management data and workload information.

• Identification of technical risks, especially with dynamic calls, configuration-dependent behavior, authorization checks, and table read/write logic.
• Creation of a well-founded assessment of migration capability, documentation quality, and suitability of the model as a basis for fit-gap analyses and specification work.
• Consulting the client team on deriving target states, cleanup measures, decommissioning potentials, and technical priorities.
• Review and assessment of functional and technical specifications for customer-specific SAP objects, and ensuring traceability from requirement to test.
• Close coordination with business departments, development, architecture, and SAP CoE, as well as clear documentation of assessments, assumptions, and architectural decisions.
