Agreed @NachJo, hopefully this information can provide some insight to help someone else solve a problem they might be facing!
As of now, the best option we have would be modeling the purchased tablet “kits” as BOMs with their individual components. You could even keep it to just the two components for the sake of simplicity:
- The charger/cable
- The tablet and other extras
Then you could model the other charger options as their own parts, and create revs of your tablet kit BOM that represent the possible tablet/charger combinations.
This still isn’t a perfect solution on the PO side. Buy the kit as a BOM revision (whichever one is most often bought), then switch out the charger part numbers as needed, using some inventory adjustments to account for the charger you are replacing on the tablet.
But different BOM revisions allow you to track the contents of the tablet you buy and switch out the contents as needed.
