Probably don't make sense but I need an ID# that goes up in increments of 1 and is issued to a new record when created. I tried the Serial number thing in the define fields menu but if a record is deleted that number is not replaced. The ID format is PE1, PE2, PE3, etc.

thx

The easiest way is to not delete the record, but empty it out and mark it for recycling. Then script the New Record process to only create new records if there are no records for recycling.

Alternatively create another file that contains the list of deleted ID numbers and recycle these. But be careful, most methods can come unstuck in a multi-user environment.

May I ask why you need to recycle serial numbers? This is a question that comes up from time to time, and often, there is no particularly good reason for doing it, but lots of good reasons for *not* doing it.
