Pickup batch of totes from several different racks

[ FlexSim 22.0.0 ]

Hi everyone, I have a problem with picking batach (4 ) of totes from several racks using list and deliver to one queue.

I asked for somethig simmilar, but that was different case Unloading Batch.

In this case I have a RackList with all of the totes in Warehouse. Totes have some lablels ex. ID number. In table Mrowa_1_tab (order list) is list with ID I need to deliver to one queue.

I used pull from List where I compere ID of tote from the warehous and ID from the Mrowka_1_tab, to pull only the totes there are in order list.Using the previous solutions it doesn't work.

Here is my model

What doesn't work? Your tokens do pull things off the list. But you don't need the subflow to pull 4 items - just put 4 in the quantity to be pulled and instead of using AssignTo - select InsertAtFront of for the pulled array.

Having done this you will see that you don't have 4 things on the list with that index number so it will stop.

Thanks @Jason Lightfoot for your answer ,but I'm afraid we misunderstood.

Let's chceck my model attached.

When I delete query form PullFormList it works. But it pull all of the totes form the RackList.

The thing I would like to do is to Pull only the totes which are in the order list - Table "Mrowka_1_tab" .I need to compere these two values (ID in the table and ID in RackList)

When you call runSubflow and create 4 tokens they all have the same value for "Indeks" since they are copied from the token with tokenIndex1. So you can 4 tokens trying to pull items with 2 off the list.

Why are you creating 7 tokens (the number of rows in the Parameters_Tab table)?

You could create the number of picks in Mrowka_1_tab and batch them in groups of 4 aggregating the ID number into an IDs array. I show this in the attached model. You need to specify the token.Unload label somewhere.

Thank You for your help! It works 🙂

PS: I sampled by mistake the Parameters_Tab to create tokens...

Ah - okay - an easy mistake to make.
