RE: scan serialnumbers into database
Michael - keep in mind this is a retail management application; retailers only really need to track the serial numbers of what they receive into their inventory, and what they sell / transfer out of their inventory. I have a hard time wrapping my mind around your objective here - why do you need to track a million serial numbers for a serial item? Also, scanning a million serial number barcodes is going to make some index finger quite sore, lol...
Tell us what you are trying to accomplish - maybe there is another or a better approach. If you have the list of serial numbers on an excel sheet, or a flat file, you can import the file onto a temporary database in your RMS database, then INSERT against the serial number tables from that temporary database.
Hope this helps.
