Data engineering on BDC works when patterns respect the governed-semantic foundation, not when BDC is treated as a generic Spark cluster. Medallion (bronze/silver/gold) with an SAP twist: governed data products (M033) often already provide the conformed semantic layer — engineer silver/gold on top, don't re-bronze. Delta Lake gives ACID (safe re-runs), time travel (reproducible/auditable results, M077), schema evolution (contracts grow without breaking consumers). Incremental/CDC, not nightly full-reload (volume discipline, M071). Idempotency (merge/upsert on keys) is the reliability pattern — non-idempotent pipelines double-count on retry. Dependency-aware orchestration + loud observability (M045) — silent failure lets bad data reach a decision. Batch by default, streaming only where the decision needs it (M095). Trustworthy+performant pipelines on governed SAP data is the rate-setting skill.

What you will learn

  • Understand the core patterns behind BDC data engineering — medallion, Delta Lake, incremental, idempotent
  • Apply Patterns in a typical SAP analytics engagement
  • Recognize the 3-5 common mistakes and how to avoid them
  • Position this skill in your personal brand and rate conversation

Module overview

Data engineering on BDC is where SAP business data meets lakehouse-scale processing — and the patterns that work are the ones that respect the governed-semantic foundation rather than treating BDC as a generic Spark cluster. The consultant who brings disciplined engineering patterns (medallion, incremental, idempotent) to governed SAP data products delivers pipelines that are both performant and trustworthy.

The medallion architecture, SAP-aware. The bronze/silver/gold pattern organises data by refinement stage: bronze (raw ingested), silver (cleansed, conformed), gold (business-ready aggregates). On BDC the twist is that the governed data products (companion module M033) often already provide the conformed, semantic layer — so the engineering question is "what do I add on top?" not "rebuild from raw." Re-bronzing data that already arrives as a governed product is wasted work; engineer the silver/gold transformations the specific use case needs.

Prerequisites
