Browse to your microvellum folder and check here "\Microvellum\Help\Support Files\Reports\ALIS Product Tracking" There's a shipping report of the cabinets that get scanned. And there's also a not shipped report that populates remaining cabinets from the release being scanned. This is the reports we use. They look exactly like the product summary report.
A few things to lookout for with scanning and ALIS, like you already mentioned; scanning the same barcode more than once is possible. And also, once you start scanning products for a specific release, The not shipped report will always keep in memory what is remaining to be scanned from that release. I cannot find a way to reset the not shipped report and start over again.
