New SuiteScript 2.1 Execution Preference in NetSuite 2026.1

Starting in NetSuite 2026.1, a significant update allows developers to execute SuiteScript 2.0 scripts as SuiteScript 2.1. This enhancement facilitates smoother transitions and greater compatibility for scripts that were originally written in the 2.0 syntax. This change is part of a broader set of enhancements aimed at improving script execution and integration capabilities in the platform.

Key Features of the Update

• Preference for Execution: A new configuration option enables the execution of SuiteScript 2.0 scripts under the SuiteScript 2.1 framework, lessening the need for developers to rewrite legacy scripts.
• Support for PATCH Method: Both N/http and N/https modules now support the PATCH method, which allows developers to make partial updates to records and data.
• Integration Enhancements: Introduction of a new subtab in the execution log specifically for the AI Connector Service, aimed at aiding integrations.
• Sandbox Exception Management: Enhanced exception management functionality is now available in sandbox environments.
• Advanced Reporting Features: New support for consolidated reports and an upgraded SuiteQL tool within the MCP Standard Tools offers enhanced reporting capabilities.

1. Enable Script Execution Preference: Navigate to the preferences section of your account and enable the option to run SuiteScript 2.0 as 2.1.
2. Update Existing Scripts: For those with existing SuiteScript 2.0 scripts, consider gradually updating them to leverage 2.1 features for better performance and capabilities.
3. Utilize Logging Features: Make use of the new logging capabilities for custom tool scripts to diagnose and troubleshoot issues efficiently, ensuring you add necessary JSDoc tags and define entry points correctly.
