Remove empty pallets from rack

Hi everyone, I have a model where my inbound pallets with boxes will be placed on racks, and the boxes will be picked based on a picking list. I need to create a trigger that does this - whenever there is an empty pallet (all boxes were picked from that pallet), the pallet will be transferred to a sink to create empty space on the rack for new inbound pallets.

Does anyone have any idea how can I do this? Many thanks!

When ever you pick an item from your pallets, then you check the content:

item to pick: item.up is a reference to the pallet. item.up.subnodes.length is the content of the pallet.

If the content becomes 0 then you create a transport job for the pallet.

Appreciate your help Joerg, I am quite new to flexsim...How do i go about to create a transport job? What i have in mind now is to write a code for the rack on exit trigger but not sure is it a correct approach...

@yc123, do it. Test it. And if you have problems, you ask a new question or if your question has got a strong relation to your question here, then as a comment here. Please consider to do it in Process Flow.

Have you been through the tutorials in the online help? Exit would be too late if creating it on the rack - it would be when you release an item through a port.

If you have process issuing the pick jobs then it's at the last pick even that you would release the pallet or create a task sequence for something to remove it using task related activities (see the tutorials).
