can't select "replace with after effects composition"

I watched many tutorials and they all tell me to right click on the clip and select "replace with after effects composition" in Premier pro cc 17 which would open the selected clip into after effects so I can edit effects on the desired clip. When I right click it I can't select that option because its grayed out. Can someone help me out? "Adobe Dynamic Link" is also grayed out in drop down window.
