If you're referring to the situtation where you pressed the transmit button for AMCAS, but you're application isn't complete the short answer is yes. I just took the August MCAT so my application isn't complete, but I've received 2ndary's from Ohio State and Cincinnati. AMCAS just sends the schools your name and e-mail address to let them know you'll be applying. The schools that don't screen for secondaries will invite you to fill out the secondary. Some of the sites require a password which is provided by the school.
