Why Dual-Engine SQL Matters (MSSQL + PostgreSQL) — Field Guide addresses a problem most SAP landscapes know too well: Stale warehouses and failed night jobs undermine dashboards the C-suite already promoted.

The SQL Project Cockpit defines source objects, target tables, field mapping, delta parameters, and schedules — monitored in SQL Job Monitor with package-level error detail.

SQL Transfer moves SAP data to MSSQL or PostgreSQL using project-based jobs with methods I (full refresh), A (append), U (upsert), D/L (delta), package sizing, and parallel processing.

Capabilities you use in iDataEngine

  • Package size and parallel processing
  • SQL Job Monitor with cron schedules
  • Masking on SAP → SQL direction
  • MSSQL and PostgreSQL dual-engine parity
  • Methods I, A, U, D, L with delta parameters
  • Project clone and monitoring KPIs

Recommended workflow

  1. Extend the same definition to the next channel (API, SQL, MF, BI) without redesigning from scratch.
  2. Configure source objects, fields, mappings, or rules using session language and customer/system context.
  3. Open the relevant cockpit (iDataView Explorer, SQL Project, API Service Detail, or AccessGuard).
  4. Save and capture the generated URL, job ID, or snapshot reference in your change record.

Real-world scenario (2025)

E-commerce stock sync every ten minutes via upsert into PostgreSQL — website stays fast when SAP is slow because SQL Transfer owns the cache layer.

Why it matters

Delta methods save SAP and SQL load; upsert keeps master data current without full-table deletes that frighten operations.

Your next step is a controlled pilot: Test in cockpit, save with evidence, then extend to the next channel without redesign.
