4.5.9 Trigger Functions
A LANSA trigger function is a special type of LANSA function, which is invoked automatically when a specific type of I/O operation occurs on a file and when a specific set of conditions are met.
There are 2 building block application templates available, designed to form the base of a trigger function: one for field-based triggers, and one for file-based triggers.
A trigger should encapsulate all the trigger rules for a particular field or file, (depending upon whether the trigger is linked at field level or file level).
