Greetings Team!

I am relatively new to Laserfiche Workflow and have only worked on basic tasks so far. I currently have a folder containing various files, each beginning with a specific code. My goal is to identify the latest file created, extract the code from its name, and then copy a file from another folder into this directory, while also modifying the name of the new file.

I've done some research on how to achieve this. I understand that by using "find entries," I can retrieve the file names and determine the most recently created file. However, I am encountering some challenges. I have attached a reference image for clarification. Could you please provide guidance and assistance?
