Auto number column in SharePoint list

Question

In a SharePoint list I want an auto number column that as I add to the list gets incremented. How best can I go about this?

Answer 1

I had this issue with a custom list and while it's not possible to use the auto-generated ID column to create a calculated column, it is possible to use a workflow to do the heavy lifting.

I created a new workflow variable of type Number and set it to be the value of the ID column in the current item. Then it's simply a matter of calculating the custom column value and setting it - in my case I just needed the numbering to begin at 100,000.
