The way I'd do it would be to have the source create the pallet and then create a box through other means immediately afterwards and move it onto the pallet.


One way would be to use process flow: An event triggered source listens to the eixt trigger of the source. The token then creates a box item an moves it onto the pallet. (You could also create the item directly in the pallet, but the placement of the box might be wrong)

The same can be done with code, directly in the exit trigger of the source.

The attached model demonstrates both methods, so two boxes are created on each pallet.

Thank you for the model.

I do not want the flowitems(pallet with box) to overlap on each other. In one of my model I am using rack and the flowitems are overlapping.

The stacking logic of the rack doesn't take objects inside the entering items into account. Is it actually necessary that the pallet and boxes are separate object or should they just look like they are?

If not, you could instead create a custom flow item that looks like a pallet with stacked boxes but is in fact just a single object. If you adjust the size of the bounding box ("More Properties" -> General Tab -> "Edit Shape Factors"), they will be stacked correctly.

Otherwise, you can add logic to the "On Slot Entry" trigger of the rack that adjusts the position depending on the height of the stacked items on the previous pallet. You will still have to limit the number of pallets per slot through a condition in the Slot Assignment Strategy though.
