Input in a combiner more than one type of a product from the same queue

In the example below it's exposed the main idea.

I want to make the combiner to pull different types of items from one queue.

Hi @Jose_francisco Co you are doing it rigth thing with the combiner, but you are changing the value of the label Type On Exit from the Queue2. If you want to change the color of the item depending on it Type label, you just have to apply the option of Color by case.

If that was not your doubt, can you explain it in more detail?

I hope it helps!

My problem is on this exercise, in the final part where are the two combiners. Thank you both!

You already have a working solution. But you overwrite the type value that gets assigned in the source with a random value in the exit trigger of the queue. If you remove that trigger you will see that the combiner pulls one item of each type (one through each port).

In the first combiner ("chassi_travessa") you should use the "On Process Finish" trigger to update the type label. The "On Exit" trigger will only fire once the item is leaving the combiner, which won't happen because the second combiner doesn't pull it due to the wrong label.

"On Process Finish" is evaluated before any send to port or pull logic, so the item will have the correct type to be pulled when the condition is checked.

Also, I believe you mistyped in the pull requirement of the second combiner. Type 5 occurs twice and type 6 is missing.

A combiner only counts items. He can counts items individually by port. But as long as you don’t restrict item attributes to special ports, you can mix all item attributes from all ports. You restrict attributes mainly in Send to Port in objects releasing items to a combiner. You can pull into a combiner items by matching attributes.
