Is the datacard variable for the number updating all configurations or is each tab getting a specific #.
If the variable does not update all configurations the @ tab would be 3000 then the default tab would be 3001. So then the next number would be 3002.
I don't have time to investigate your attachments now but I have a hunch your serial numbers are being generated in a field on the data card and one serial number is generated when the file is added to EPDM and another generated by your dispatch.
Take a look and see if you agree. I'll be able to look at it later today, maybe.
I had the update configurations box checked which was throwing me off.
Thanks Laura and Tim for your responses!
