Does smuggling the Smuggler mission roll the sneak check when you enter the planet or only at the mission point?

Question

Accepted Answer

The sneak roll is made as soon as you enter the destination planet, not at the mission point. If you are caught on the way in you learn it immediately, but you still must reach the mission point to deliver.
