Ship the SQL every supplier QBR demands

A procurement star schema: 12 suppliers (3 name-variant aliases for the same entity), 8 spend categories, 14 contracts, 95 POs with 22% off-contract (null contract_id), 88 receipts, 82 invoices. Planted data-quality issues: 3 after-the-fact POs where invoice precedes PO date; 5 PPV exceedances where unit_price > contracted_price; preferred supplier with worst lead-time performance.

PO cycle time analysis, purchase price variance, maverick spend detection, three-way match exceptions, and supplier risk scorecards — the full procurement & sourcing analyst SQL curriculum across 30 missions.

Trace the full req → PO → ASN → receipt → invoice cycle and measure cycle time at every stage.

PO Lifecycle Analysis

Compare actual vs contracted unit price to surface PPV exceedances by category — the metric that drives finance escalations.

Purchase Price Variance

Find POs with no contract_id — off-contract spend that bypasses negotiated pricing.

Maverick Spend Detection

Join PO + receipt + invoice to find quantity and price mismatches that stall AP automation.

Three-Way Match Exceptions

PO cycle time, PPV, and supplier risk.
