Hi Geert
1) Sorry I obviously misunderstood your scenario. As you mentioned both pallet and box , I assumed that the materials were boxed on a pallet and that the differences in the qty's was the number of boxes so that,
1xBox = 10PC
Pallet X = 18 boxes
Pallet Y = 21 boxes
Pallet Z = 22 boxes
Therefore, set the kanban replen qty the 18BOX rather than 180PC
2) Can be an issue (particularly with duel/multi sourcing.
3) Again based on my assumption for No1 sorry
But I think increasing the kanban qty to 220PC in this example (no need for alternative UoM) would be the simplest solution (providing of course that the kanban can physically hold 220) ??
Cheers
