Reporting - Lambda

reporting turns the active CargoWise generation into a smaller business contract. Use this layer for normal reports, reusable SQL, exports, and Power BI. Reporting views contain business reporting data only. They do not include Jaantonio technical source lineage.

Contract

Part	Purpose
Report roots	One current row per shipment or one-off quote
Detail views	Repeated charges, parties, milestones, packing lines, and other details
Relationship views	Source-backed shipment, consol, quote, and booking links
`source_fields`	Optional scalar XML evidence read from `source_data`

Each business view defines its row grain and join keys. See Schema for the complete list.

Why it stays smaller

Reporting exposes the business data needed for normal analysis. It leaves storage, replay state, generation control, technical source lineage, and deeper CargoWise structures in the underlying layers. This gives reports stable names and documented joins while the internal projection model can grow.

Compared with CargoWise

Area	`reporting`	`cargowise`
Main use	Reports, Power BI, and reusable SQL	Complex, full CargoWise consultation
Data shape	Supported business views	Fuller internal current-state model
Generations	Active generation is automatic	Query must select the active generation
Stability	Supported contract	Internal model can grow or change
Relationships	Small documented join set	Broader ownership and relationship model

When to use another layer

Use source_data for low-level XML evidence, lineage, and field discovery. Use cargowise when a consultation needs a current CargoWise structure that reporting does not expose. Next, read Data model to understand roots, details, and relationships.
