What does the "After field edit" trigger allow?

The "After field edit" trigger is designed to execute actions after a user makes changes to a field on a record but before those changes are saved to the database. This trigger is particularly useful for validating the data entered by the user based on the updates made to one or more fields. For example, if a user modifies a field, this trigger can be used to check if the newly entered value meets specific criteria or to enforce business rules that depend on the context established by other fields.

This capability enhances the user experience by allowing immediate feedback based on the user's input, facilitating data integrity within the system. Such validations ensure that only appropriate data is saved, enhancing the quality of the information managed within NetSuite.
