How to transport by pair ?

Hello,

I have a lot of items with different types from a source but I need to transport them only when I have a pair with exactly the same type. Else, the item have to stay in the queue.

Can you give us some more context or attach a model? Is the queue pushing items to other parts of the model or are things pulling from the queue?

Hello Théo,

Your model is almost complete, but some little details are missing if you compare your model with the one of @jordan.johnson.

1. In the first activity, assign a label name to the releasing item:

2. In the batch activity, select Make Array in the Aggregation column:

3. Pick a destination (Queue2) in your second travel activity:

4. The item to load is token.Item not token.Items:

Here is your updated model: 12109-example.fsm
