Hi @Vivian Wilfred​ and @Dave Wilson​ we solved our reusability code with repos and pointing the code to our main code:

sys.path.append(os.path.abspath('/Workspace/Repos/[your repo]/[folder with the python scripts'))

from your_class import *

It just works if your reusable code is in python. Also depending on what you want to do we noticed that DLT is always executed as the last piece of the code no matter what is the position in the script
