Hi,
I have some problem with my custom code. When the model run at start, the model picking box from queue 2 or 3 as intended, and send it to queue 5. And when a box arrive in queue 1, the crane will move the box from queue 1 to queue 4.
After some time, the crane will only move the box from queue 1 to queue 4 and moving the box from queue 4 to queue 5 and leaving queue 2 and 3 empty
How do i fix this in my custom code?
Hi @Andre T6,
It's hard to know how to help without looking at your model. To receive a more accurate solution, please post your model or a sample model that demonstrates your question.

Probably the content of queue 4 never exceeds 20. This happens, because for each item there is already created an transport tasksequence and it is not counted for current content. The current content is content of stored items + items in transit to this queue - items in transit to other objects. And when an item is just waiting to get transported, then it doesn’t belong anymore to the counted content of the queue. You need a customized logic, that prevents items to be send right from arriving in the queue. I would choose something like holditem or do not release item through an On Entry event. Then whenever a situation occurs where the crane gets available I would release the last item by command releaseitem Or similar action in process flow. This command calls automatically the function of Send to Port and the actual situation gets evaluated.
Hi @Joerg Vogel, I just know about holditem and release item command, how do i used it in the custom code?
And about do not release item On Entry event, i checked it in my crane, but i didn't find 'do not release item' in On Entry trigger. Where do I find it?
A crane does not release an item on entry. I said, if a crane gets available he releases an hold item in a queue. The trigger is called On Resource Available. If a queue receives an item, an on entry trigger of involved queue helds the entering item.
I will try it and maybe will ask something about this in the future if i have the same problem.
