Microsoft Dynamics NAV recognizes certain actions that happen to a table when you use it, for example, that you insert or modify data. In response, you can set up Microsoft Dynamics NAV to execute C/AL code defined in a trigger. Triggers are predefined functions that are executed when certain actions happen. The bodies of these functions are initially empty and must be defined by the developer. Defining C/AL code in triggers allows you to change the default behavior of Microsoft Dynamics NAV.
The triggers in a table can be divided into two categories:
-
Table triggers
-
Field triggers
Tables have the following triggers.
| Table trigger | Executes when |
|---|---|
A new record is inserted into the table. | |
A record in the table is modified. | |
A record in the table is deleted. | |
A record is modified in a primary key field. |
Fields have the following triggers.
| Field trigger | Executes when |
|---|---|
Data is entered in a field or when the VALIDATE Function (Record) is executed. | |
Lookup is activated. |
