The Trigger task allows you to wait for a trigger condition before processing the next task. Triggers include the existence of a specified file or the setting of a flag in a database. You can set up to three trigger conditions that all have to be met to exit the trigger successfully. You can also set a retry interval if you want this task to wait for a trigger condition. You can add this task to your package by registering OSoftTaskTrigger2008.dll located in the BPC\websrvr\bin folder, with the Microsoft SSIS interface. See Registering Custom Tasks.
