Adding a index automatically...

Hi, still new to all this I'm afraid! I've created a DTS routine that copys some table data from an Access database into another Access database. In the second mdb, I would like the routine to add an ID field and populate all the lines. I'm sure it must be kind of easy but I can't find how!

Any help appreciated.Ah sorted - just added the ID as an Identity when the table was being created in the routine.
