The SSS_METHOD_NOT_IMPLEMENTED error in NetSuite occurs when a required method in a custom plug-in type isn’t implemented or is incorrectly defined. This error often arises when NetSuite attempts to call a missing method or is incorrectly set up in the plug-in implementation.
How to resolve:
- Verify Method Implementation: Ensure the required method is implemented in the plug-in script exactly as defined in the plug-in type.
- Check Naming and Exports: The method and constructor names in the implementation should match those in the plug-in type script. Export the implementation correctly, typically as an instance.
- Test and Log: Add debug logging within the method to confirm it’s being recognized and executed.
Following these steps should help NetSuite locate and run the required plug-in method, resolving the SSS_METHOD_NOT_IMPLEMENTED error.
