End-to-end supply chain data architecture integrating SAP ERP, demand planning systems (Kinaxis, Asterisk), and master data through Google Cloud Platform services. Data flows from SAP via Cloud Dataflow into Cloud Storage, then through Cloud Dataproc ETL to populate BigQuery master data stores (Supplier Master, Material Master). Planning integration orchestrated by Cloud Composer combines SAP Month N forecasts with N+1 to N+6 demand signals via Cloud Pub/Sub into a 6-Month Requirement Plan, feeding downstream MRP and packaging workflows. Manual buyer inputs validated through Cloud Functions ensure data quality before write-back to the MDP Planning Store. This architecture demonstrates best practices for multi-source supply chain consolidation, automated validation, and real-time orchestration at scale.
