Combine by Label

[25850334]

Hi everyone, 

In my model, I am simulating an automobile service center. At the separator, vehicles and customers are separated. My problem is that I then need to join the correct vehicle to the appropriate customer at the end of the process, using the combiner. I am attempting to combine via the label "Vehicle_ID", to match the customer to the vehicle, but it does not seem to be working. 

If anyone has alternative suggestions, or can see the issue with my current model, your assistance would be greatly appreciated.

The Pull Requirement should only be used when an item is received through the second port. The combiner can receive anything through port 1. And you need to compare the label of the potentially received item with that of the item already on the combiner, not with itself.

if(port == 2)
{
	return item.Vehicle_ID == current.first.Vehicle_ID;
}

return 1;
