Answer 1

You can do this without using SQL Server Data Tool for Visual Studio by editing the dtsx File with Notepad (or any other Text editors).

Search for the following property:

<property
 dataType="System.String"
 description="Specifies options to be used with fast load.  Applies only 
 if  fast load is turned on."
 name="FastLoadOptions">
      TABLOCK,CHECK_CONSTRAINTS
</property>

and add the value FIRE_TRIGGERS as Diego already described.

Answer 2

complementing ladenedge's answer.

Because the OLE DB Destination task uses a bulk insert, triggers are not fired by default

that is true when you have the "fast load" option selected.

If you change it to a regular "table or view" data access mode, your triggers should fire normally because the insert is done row-by-row

Answer 3

Because the OLE DB Destination task uses a bulk insert, triggers are not fired by default. From BULK INSERT (MSDN):

If FIRE_TRIGGERS is not specified, no insert triggers execute.

One must manually specify FIRE_TRIGGERS as part of the OLE DB component through its Advanced Editor.

Then add "FIRE_TRIGGERS" to the value of FastLoadOptions (note that options are comma-separated):

With that option in place, the triggers should fire during the task's execution.
