I found it quite hard getting achievement "Cattle Drive" in ETS2. After some research, I did it on 20th Jan 2024.

The description of the achievement:
"Cattle Drive:
Complete a livestock delivery (requires Scandinavia DLC)"

However, the bug from many players could be the reason from this discussion " https://forum.scssoft.com/viewtopic.php?t=319580 ".
Eugene replied on 20 May 2023: "there used to be cargo "Livestock" which initially counted for the achievement, but some time ago (i assume when new livestock trailer was introduced ), livestock cargo was split into "Live Cattle" and "Live Pigs", which aren't specified for achievement." According to this reason and the fact that they added livestock trailer in 1.47 ( https://blog.scssoft.com/2023/02/ets2-ownable-livestock.html ), here are my step-by-step solutions:

1. Downgrade game to 1.46 (before 1.47 but after Scandinavia DLC should all be fine): Right click game - properties - betas - 1.46, then it would download for a while.
2. Create a new profile, name whatever, for achievement use.
3. Choose your initial garage located NEAR BUT NOT IN Scandinavia after finishing the guide.
4. Save and name whatever.
5. Use "TS SE Tool" to give you money (just Google "TS SE Tool"), and buy a truck (for your further delivering use).
6. Use "TS SE Tool" to create a job that start from your initial garage city, and to the inside of Scandinavia (whichever is ok), which contains "Live Cattle" (NOT Live Pig). Press add to list and save.
7. Load the file that you edited and then just deliver it (or you can teleport using free camera with console). It should trigger the achievement "Cattle Drive".

Hope this guide helps you. Feel free to like, gift or comment if you like, have any suggestions or questions!
