To be honest there is no necessity for a guide on how to get this achievement. Since you cannot fail it. However there seem to be quite a few problems with the achievement unlocking system of this game and the Xbox one in general. So I thought it could be useful to have a little reminder when this achievement should unlock so you know that nothing glitched for you.
I will mention the actions you have to participate in right before you get your achievement below.
Just in case you need further information about the situation described above you can refer to the video below (video credit: Frawgz Gaming)
Hope this helps you guys!
Any improvements? Please let me know in the comments below!

This trophy is story related and therefore cannot be missed.
Near the end of the chapter, you will go down the elevator into the Batcave and see a news report about Batman (yourself) fighting Catwoman. Turn to your left and press 
to pick up the Data Drive, turn back to your right and press on the Data Port to analyse the Data Drive.
After eventually accessing the Data Drive, you’ll have a hologram of a map appear. Rotate around the map using 
until it zooms onto the purple-shaded area. You'll then have to access the Codex by pressing on the left screen back on your computer and select Car Burglar (far right). Afterwards, press 
twice to exit the Codex and you'll have a brief conversation with Alfred. Press to take the Business Card. You'll then analyse on the computer and discuss about Oswald (Penguin) with Alfred. The trophy will pop at the end of conversation.
