In Part 1 we extracted a BW system's metadata into a single DuckDB file with erpl-adt catalog sync — 53 cubes, 226 queries, every characteristic and key figure, all the lineage between them. Browsable, searchable, and completely decoupled from SAP.

Now we do the interesting thing. We unplug.

No SAP credentials in this post. No VPN, no connection, no --host. Just catalog.duckdb — the file from Part 1 — and an AI agent. The goal: take one cube (0D_NW_C01, "Actual for NW Demo") and its flagship query (0D_FC_NW_C01_Q0008, "YTD Sales by Sales Org") and reverse-engineer them into runnable dbt models on DuckDB. Reconstruct the star schema, the measures, and the year-to-date logic — from metadata alone, offline.

Here is exactly how it went.
