Grand Theft Auto V

Each of the five heists available in the Heist Update include multiple “Heist Setup” missions that need to be completed prior to playing the “Heist Finale” mission. After being called by Lester, a green “H” icon inside your apartment on the world map will represent each of these Setup missions. The first Setup mission available is for the tutorial heist entitled, “The Fleeca Job.” 

The first of two Heist Setup missions available here involve the crew traveling to Fleeca Bank on the western highway, scoping out the security system, and then collecting a contact and some supplies from Lester’s warehouse before returning to the apartment. Once this Setup mission has been successfully completed, the achievement will unlock without issue.
