Hi - I have a dataset where the [User ID] field could be similar across a various number of rows (they are not duplicate records, as other fields are different). I just want to assign a unique number to any row or groups of rows with matching [User ID]. So if there are 3 rows with [User ID]="123", they would all get a new ID field with the same number, as shown below.
User ID Record ID
123 1
123 1
456 2
789 3
789 3
789 3
789 3
