Triggers when inserting data with DTS

Hello All,
I have a table that is filled up with data using a DTS. I have made a trigger for this table. The trigger is:
CREATE TRIGGER tgrName ON [dbo].[table]
FOR INSERT
AS
insert into table_audit
select 'INSERT' AS [ACTION],GETDATE() AS ACTION_DT,* from Inserted
When the DTS runs and fills with data the table, the trigger does not fire and the table_audit does not fills either.
Can anyone help me?
Thank you on advance

Are you using BULK INSERT in the DTS? Maybe the trigger isn't firing because it's a non-logged operation. I suspect this is the case, need to do some reading to check it out though.

I use a Transform Data Task.
I went to the Properties > Option and unchecked the "Use fast load" tickbox. No the trigger is firing and everything seems OK. I don't know what this "Use fast load" does. I would appreciate if anyone could tell me.
Thank you.
