@joey S

In the attached model, I have set the "Type" label to the created items in OnCreation trigger of each source. Then I have used ByExpression in the Send To Port parameters in the Queue's flow property tab.

itemtype-support-1.fsm

Hope this helps,

Thanks

Hi @joey S,

The queue sends items to a rack based on the item type. The queue looks at what type of item it is, then matches that with the number of output port.

Rack 21 is connected to output port 3 and so Queue1 cannot send items to Rack 21 because there aren't any items that are Type 3.

If you wanted to send items to that rack, you'd have to either create Type 3 items or change your logic.

I would let the racks pull the items. When the first item of an empty rack is pulled, the item type value is stored to a label at the rack. Then the rack pulls only items matching this item type until the rack is empty again. Then the rack pulls every available item. This defines the next Type in the rack. And so on.
