More items being created than intended

Hey all,

I am using a processor (which would be an automated carton opener) to move the carton to the takeaway line and move all the individual items to the intended conveyor. The issue I am having is that I am only expecting one item to come out on to the conveyor, however, it is spawning in another item and another carton at the takeaway line for some reason. I tried stepping through the process flow and was a little confused on why more physical items were being created.

Thanks,

Amit

Hi Amit,

Could you explain a little more on your issue? Maybe using screenshots to show what you are confused by?
As of right now the Process Flow has a "Wait for Event" activity that is listening to the Processor1 when it finishes. The process flow then moves the tote to a conveyor and the box to another.

I have the quantity of each tote to only contain 1 box in it. The issue I am having is that on the wait for event activity, it is seemingly creating a duplicate token which is in turn creating another unwanted box and unwanted carton in their respective locations (as shown in the screenshot, there are two boxes on the conveyor next to the decision point and two totes on the takeaway line, but it should be one on each).

I believe that the issue is stemming from a small error on the Wait for Event activities:

When Processor1 fires On Process Finish, it will release all tokens at the Wait for Event. In order to only release the token that actually triggered the Processor1/On Process Finish, you want to put in the name of the label (which you did) and then select "Match" (which is missing).

You'll want to do the same on your other Wait for Event.
