I´ve been trying to model a process in which pallets get filled up and get transported afterwards. For this i used assemblies, which works just fine. The problem i encountered was that the process transportIn step does not differentiate between the boxes to place and the pallets themself. This ends up in stacking pallets in a wierd way. The goal is to place a new pallet whenever the assembly was finished. Is there a way to specify allowed input parts in the process?
