question

Hi David,

I took a look at your model, and I made some changes. First, I made it so boxes from Source15 can only find slots in the Racks 15, 16, 17, 19, 20, and 21. I did this by painting an Area label on those racks with the value 2. I also added a line in the query:

WHERE SKU IS $1.SKU AND Area = 2 ORDER BY...

Then I disconnected Queue2 from the other queues. The issue is that when Queue2 receives an item, the Process Flow assigns a slot, but Queue2 doesn't know about that. It will always send items using the default logic for the queue, including making a task sequence, which you are also making in process flow. Since boxes need to go to the staging queue based on where they were assigned, I let Process Flow make the correct task sequence.

There is a similar problem with the queues just before the racks. I set those queues to not release the flowitem. In the Process Flow, I used the inobjects of the racks to figure out which queue the box should go to. The first task sequence gets the box to the correct queue, and the second gets the box to the correct rack.

Hopefully, that makes sense. Let me know if anything is confusing.
