TE loads to it's capacity

A TE loads items from Queue1 to Queue2.
The capacity of the TE is 10.
I want it to load three items, then go. If there is not enough item in queue1, it will wait.

I don't want to use batch of queue1, because the TE should load any item when arrived.

how to do it?

thanks

Qin,

You could try creating your own RequestTransportFrom code. Instead of creating a task sequence to load - travel - unload you could create a task sequence to only load. Then in the OnLoad trigger of the TE you can check and when the 3rd item is loaded create a new task sequence to travel and unload each item.

Good Luck,
Brandon
