Which of the following is not an available server trigger?

The correct answer identifies that "After user submit" is not an available server trigger in NetSuite. In the context of server-side scripting, particularly with SuiteScript, triggers serve specific purposes and occur at defined points during the record lifecycle.

The available server triggers, such as "Before record load," "Before record submit," and "After record submit," are integral to the process of scripting around record management. "Before record load" is triggered before a record is retrieved from the database, allowing scripts to manipulate data or perform checks before it is presented to the user. "Before record submit" executes during the record's save operation, providing an opportunity to validate or alter data before it is committed to the database. "After record submit" occurs after the record has been successfully saved, allowing for actions based on the newly persisted data.

In contrast, "After user submit" does not correspond to a defined trigger within the SuiteScript framework. This term does not align with the specific lifecycle events that NetSuite scripts can leverage, which is why it is the correct choice for this question. Understanding these triggers and their purposes is vital for effective scripting and record handling in NetSuite.
