Mission Overview:

The role involves configuring the SAP Data Services tool to facilitate the integration of data extracted from SAP ECC and performing all necessary data transformation tasks before loading into S/4HANA.

Mission Scope:

The mission encompasses the configuration of the SAP Data Services tool, integration of data extracted from SAP ECC, transformation and enrichment of data within SAP Data Services, and feeding staging tables for loading this data into S/4HANA.

Expected Deliverables:

  • Configuration of all mapping, transformation, and enrichment rules as communicated by the Migration Consultant and validated by functional teams.
  • Optimize tool performance based on data volumes to be processed.
  • Create reports to reconcile extracted data, data to be migrated, and transformed data (Note: reports cannot be generated with SAP DS – either manually (CSV/Excel file) or using PBI or other tools).
  • Configure controls to verify data quality before and after transformation.
  • Create reports to facilitate data validation by Data Managers after transformation and before (outside SAP DS).
  • Document data flows, rules, and transformation processes in technical specifications.
• For each migration run:
  • Launch data extractions.
  • Verify the completeness of extracted data.
  • Simulate and then execute the transformation of this data.
  • Perform checks on transformed data.
  • Produce reports for Data Managers who must validate the data after transformation.
  • Populate the Migration Cockpit staging tables with transformed data.
  • Adjust rules as necessary based on validation feedback collected by the Migration Consultant.
  • Adhere to deadlines mentioned in the migration schedule for each run.
  • Suggest any improvements in the data processing workflow.
• Immediately relay any critical issues or potential risks to the Workstream Lead Migration.
• Work closely with the Workstream Lead Migration and the Migration Consultant.
• Regularly and comprehensively report progress to the Workstream Lead Migration.
• Under the management of the workstream/Domain lead, collaborate closely with the project team and internal SAP teams to understand needs, identify process improvement opportunities, and propose suitable SAP solutions.
• Under the management of the Lead Architect, provide architectural solutions and necessary information for the design and construction of processes within the requested project scopes.
