I want to create and display a unique ID for a record once I have created a new decision

[Allan Parsons]

Using the out of the box decision template, I am looking for a way to incorporate a auto increment field for ID.

I don't want each row in the table to have an ID (i know how to do this) but I want 1 row in the column to be a unique id which auto populates when a new decision is created.

What is the best way to do this?
