Problem
Employees moved between the group's subsidiaries, and each SAP HCM instance issued its own ID. The same person existed as several unconnected records, so no system could show a complete career history.
Method
Consolidated the records in Power Query and matched people on a composite key of name, date of birth and national ID. One verified history per employee was loaded into SAP SuccessFactors, then Employee 360 reporting was built on scheduled extracts through Excel and Power BI, later moving to QlikSense and the group's AWS platform.
