identity DB field in Data Dictionary Table

Hi

I am using NW04 SP9

I created a Data Dictionary DC and created a new TABLE.

I need one of the fields to be an IDENTITY field (that generates an ID automatically whenever a new record is craeted).

Q1. Is the Data Dictionary DC and Plug in (of NW04 SP9) support such a feature?

Q2. If the answer is no, what are my alternatives?
