If you make a field called LOT, and each of those records (items) have the same lot number.
You would do a find for that lot number and only those records would be found.
In list view, you would see three entries.
In form view, you could advance through the three items.
For example, if Widget 5, Widget 7, and Widget 124 all relate in some way (maybe they're all part of the same lot)
Maybe there would be a table of Lots and another table of Widgets - and they would be related by LotID.
when I pull one of the three up in my details layout, I can see the other two and quickly find them (e.g. click on a link perhaps).
If you define a relationship of the Widgets table to itself, matching on LotID, you can show the related widgets in a portal.
