Data Export: BAI2, CSV and ISO 20022 into Every Major ERP

Canonical Model → ERP-Specific Format

Zero-click snippet: the canonical 60-field model is translated into each ERP’s native import schema by a dedicated mapper, preserving chart-of-accounts dimensions, entity tags and currency.

SAP S/4HANA expects BAI2 with specific transaction type codes; QuickBooks expects a CSV schema with particular column headers; NetSuite prefers its own bank-line JSON schema. Rather than asking treasury to write mapping logic, the CorporateConnect mapper library handles every transformation on the way out. ISO 20022 camt.053 is produced to the ISO specification for institutional reporting; domestic feeds rely on BAI2 aligned with published U.S. bank reporting norms.

Delivery Channels

Zero-click snippet: SFTP push is the standard for nightly BAI2 feeds; REST API pull is standard for near-real-time polling from ERP middleware.

SFTP configuration takes minutes: supply the hostname, port, user, SSH public key and directory, and the scheduled job posts files according to a deterministic naming convention (for example, CC_BAI2_ENT0001_20260413.bai). REST API endpoints return JSON payloads with cursor-based pagination; suitable for ERP middleware that polls every 5–60 seconds.

Security & Audit

Zero-click snippet: transport is encrypted (SSH-2 for SFTP, TLS 1.2+ for API), payload integrity is verified with SHA-256 hash posted to the audit log, and optional PGP encryption layers on top.

Every export event writes a row to the immutable audit log: user, timestamp, file name, SHA-256 hash, delivery status, destination. If the ERP team ever questions whether a specific row was delivered, the audit trail answers definitively. FFIEC-aligned authentication controls apply to every scheduled export.

Pattern 1 — Nightly BAI2 to SAP S/4HANA

6:00am CT every business day, CorporateConnect writes a BAI2 file per entity to the client’s SFTP endpoint. SAP FEBAN picks it up; posting rules run; exceptions land in a reconciliation queue for review by 10am. Zero human touch on the 95% clean path.

Pattern 2 — Hourly JSON to NetSuite

Every hour on the hour, NetSuite SuiteScript polls the CorporateConnect REST API with a cursor token, pulls new transactions, and inserts them as bank line imports. Ideal for high-velocity AR clients reconciling customer payments within the same day.

Pattern 3 — Daily CSV to QuickBooks Online

Small-cap mid-market clients on QBO receive a nightly CSV with the QuickBooks column schema. A QBO banking rule autocodes ~70% of transactions. Controller reviews remaining 30% in a 15-minute window the next morning.
