Table and Field Triggers in Dynamics NAV
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 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 Dynamics NAV.
The triggers in a table can be divided into two categories:
Tables have the following triggers.
|Table trigger||Executes when|
|OnInsert Trigger||A new record is inserted into the table.|
|OnModify Trigger||A record in the table is modified.|
|OnDelete Trigger||A record in the table is deleted.|
|OnRename Trigger||A record is modified in a primary key field.|
Fields have the following triggers.
|Field trigger||Executes when|
|OnValidate (Fields) Trigger||Data is entered in a field or when the VALIDATE Function (Record) is executed.|
|OnLookup (Fields) Trigger||Lookup is activated.|
