Executes when a user modifies an existing record in a table.
Applies To
Tables
Remarks
This trigger executes before the default modify behavior is
executed. If an error occurs in the trigger code, the record
changes are canceled.
We recommend that you do not include code that can stop the user
from recording a change in the OnModify trigger on a table. For
example, do not include code for displaying error messages. If a
user has previously changed the contents of some fields in a
record, then these changes must always be accepted by the
system.
