Re: How Trigering is achieved in Biztalk

Many times in such scenarios the trigger is when the flat file appears in the input folder.  The file adapter polls the folder every few seconds and when it discovers a message, it delivers it to any orchestrations or send ports that are listenening.  If you want the trigger to be more of a scheduled event, then you could configure the receive port to use a service window.  For example, if you want you receive the flat file at 1:00, but you want your process to run at 2:00, you could configure your receive port with a service window of 2:00 – 3:00.
