OnBeforeModify (Table Extension) trigger
Version: Available or changed with runtime version 1.0.
Runs when a user modifies an existing record in a table.
Syntax
trigger OnBeforeModify()
begin
...
end;
Remarks
This trigger is run before the default modify behavior, which checks that all the fields of a record are valid before the modification occurs. It runs automatically when the user changes at least one field (different from the primary key field) of a record in a page from the Web Client. If an error occurs in the trigger code, the record changes are canceled.
