Tracking event timeline for a shipment

Ship the SQL every carrier QBR demands

A logistics & transportation star schema: 8 carriers (one "late-but-complete" trap carrier), 16 lanes across 4 regions, 120 shipments with planted OTIF failures, 110 freight invoices with 4 overbilled loads, and 420 tracking events with duplicate DELIVERED scans. Planted data-quality issues: carrier MISS has 97% in-full but only 71% on-time; two facilities have dwell > 2 hrs on >35% of loads; 4 invoices exceed contracted linehaul by >10%.

Carrier OTIF, freight invoice audits, detention hot spots, cost-per-unit benchmarking, and multi-metric carrier scorecards — the full logistics & transportation analyst SQL curriculum across 30 missions.

Build the on-time AND in-full formula at PO-line grain — the exact logic Walmart enforces with a 3% COGS chargeback.

OTIF Compound Metric

Find overbilled invoices, accessorial overcharges, and contract rate violations across carriers and lanes.

Freight Invoice Audits

Identify facilities where dwell time exceeds 2 hours on more than a third of shipments — the hidden cost every logistics manager wants to cut.

Detention Analysis

Combine OTD, fill rate, cost per unit, and dwell into a ranked scorecard using multi-CTE queries.
