SQL Server 2008 :: How To Set Up Triggers After SSIS Dump

I am would like for a Trigger to fire after an SSIS job finishes.

My understanding is that i would use a AFTER trigger.

How my UPDATE and INSERT INTO would fire and only affect the new rows.

SET ARITHABORT OFF
SET ANSI_WARNINGS OFF

UPDATE [GDev].[dbo].[tblCIDetailsTest]
SET dFRate = (dFCharge/(dSCharge+dACharge))

Also need to INSERT INTO 3 columns from a Table called tblFinanceP by looking up/Union or Join (not sure what to use) called vcTNum that is in bother the tblFinacneP and tblCIDetailsTest.

INSERT INTO [GDev].[dbo].[tblCIDetailsTest] AS Details
SELECT iPNum, iPCount, iZone
FROM [GrEDI].[dbo].[tblFinanceP] AS EDI
where EDI.vcTNum = GDev.dbo.tblCIDetailsTest.vcTN
