Release Intelligence Separately-licensed SyntraFlow module

How SyntraFlow Release Intelligence Works

Release Intelligence is a SyntraFlow module that is licensed and priced separately from the core SyntraFlow test automation platform. It pinpoints exactly what each Oracle Fusion quarterly release or critical patch will affect in your tenant — and produces the test scenarios needed to validate it. The workflow runs in five connected steps:

  1. Connects to your Oracle Fusion environment. A secure read-only connection to your live Oracle Fusion tenant ingests setup data, security model, and live transactions — no manual exports, no spreadsheets.
  2. Scans your complete configuration with Config Intelligence. Config Intelligence snapshots every setup object (FSM tasks, profile options, BPM rules, descriptive flexfields, security policies) and compares it against the incoming release.
  3. Reads master & transaction data via DataVault. DataVault profiles your real master data and live transactions so impact analysis is grounded in what your business actually runs — not generic Oracle samples.
  4. Produces a detail-level Impact Map. Cross-references the release notes against your configuration and data to highlight which features, flows, integrations, and reports are at risk — down to the line-level setting or seeded role that changed. See Release Impact Analysis.
  5. Generates test scenarios & remediation report. Outputs ready-to-execute test cases targeting each impacted area, plus a remediation report with the exact steps to update your setup or data so the patch goes live with minimum disruption. Run them with Patch Testing Automation.

Licensing note: Release Intelligence is a standalone SyntraFlow module available as its own subscription, or as an add-on to the SyntraFlow test automation platform. Pricing is separate from the core platform — contact us for module pricing and bundling options.
