Upcoming Oracle EPM Groovy Engine Update: What You Need to Know

 Oracle has announced a significant update to the Groovy engine used in Oracle Enterprise Performance Management (EPM) Cloud, scheduled for release in the second half of 2025. This update introduces stricter validation rules that may impact existing Groovy business rules, potentially causing previously valid scripts to fail validation. 1

🚨 What’s Changing?

The upcoming Groovy engine update is part of Oracle’s ongoing efforts to enhance the robustness and maintainability of EPM Cloud applications. However, with these improvements come stricter syntax and type-checking rules, which means:

• Scripts that previously passed validation may now fail.
• Common issues include improper use of data types, outdated syntax, and incorrect variable referencing.

🔍 Key Validation Changes to Watch For

According to Oracle’s documentation 2 , here are some of the most common issues that could trigger validation errors:

• Improper use of implicit typing: Replace def with explicit types like String, int, or List<Double>.
• Incorrect variable referencing: Use the rtps.variableName format instead of {variable} or [variable].
• Floating-point precision: Use the d suffix (e.g., 1212.34d) to ensure values are treated as double.
• Deprecated functions: Replace old Date functions with Calendar equivalents.

🛠️ Oracle’s Support Tools

To help customers transition smoothly, Oracle will release a diagnostic tool in the August 2025 update. This tool will scan your existing Groovy rules and identify those that need to be updated to comply with the new validation rules.1

You can find detailed guidance and examples in Oracle’s official documentation: Resolving Groovy Business Rule Validation Issues.

✅ What You Should Do Now

1. Review your existing Groovy scripts in Calculation Manager.
2. Start refactoring using the new syntax and best practices.
3. Bookmark the August 2025 update to access the diagnostic tool.
4. Test your rules in a sandbox environment before the update goes live.

📌 Final Thoughts

While this update may require some upfront effort, it ultimately leads to more stable, secure, and maintainable Groovy scripts in Oracle EPM. By preparing early and leveraging Oracle’s tools and documentation, you can ensure a smooth transition.
