GCP Pipeline Reference: Generic CDP Transformation — dbt models for FDP to CDP (JOIN pattern across all 3 FDP tables)

fdp-to-consumable-product

Deployment type: BigQuery (dbt) Layer: CDP — Consumable Data Product Pattern: JOIN across 3 FDP tables → 1 CDP table

Overview

This deployment builds the CDP (Consumable Data Product) layer by joining all three FDP tables from fdp_generic into a single denormalised view per customer:

fdp_generic.event_transaction_excess    ─┐
fdp_generic.portfolio_account_excess    ─┼──► cdp_generic.customer_risk_profile
fdp_generic.portfolio_account_facility  ─┘

The customer_risk_profile CDP table is the primary source for the mainframe-segment-transform pipeline, which reads each row and writes an outbound fixed-width segment file back to GCS for downstream mainframe consumption.

Data Flow

ODP (odp_generic) ──► FDP (fdp_generic) ──► CDP (cdp_generic) ──► GCS segment files
       ↑                    ↑                      ↑                      ↑

                       mapped-product)                            transform)

CDP Table: cdp_generic.customer_risk_profile

One row per customer per extract date. Combines:

Source FDP Table	Fields
event_transaction_excess	customer identity, account exposure, current balance
portfolio_account_excess	risk decision, score, decision outcome
portfolio_account_facility	loan amount, interest rate, term, facility status

Derived field cdp_segment:

• ACTIVE_APPROVED — decision approved + positive balance
• DECLINED — decision declined
• REFERRED — decision referred for manual review
• PENDING — no decision yet
