Hi, 
So i've been searching all around on how i could increment a column in Teradata. I'm new to this so im not really familiar with all the syntax or tactics that i could use. 
I've read about autogenerated identity column, OLAP and recursive in teradata but i think it does not matches my need. 
So here's my problem.

Hi Forum,

I have a table created as SET table using IDENTITY column as UPI and it has data in it.

Now, the user wants us to change it to MULTISET, but, as the PI is on Identity column how can I do this?
