Warehouse Simulation - Create an item list for orders

I am making a warehouse simulation where 2 people place 4 types of items (A,B,C, "Large") onto racks. Then, 2 other people pick the items from the racks onto pallets. The warehouse racks are color coated as each item has designated racks. Currently, the orders have a random quantity of each item.

I would like for each order to require 20 items: 15 of A, 3 of B, 1 of C, and 1 of "Large".

Additionally, I would like to be able to generate the arrival specific quantities of each item. Ideally, each arrival is a pallet with 20 items (15 of A, 3 of B, 1 of C, 1 of "Large"). I have attached my file.

The amount of items going in and out are the same. Placing them is just a process flow that creates items in your model() reference, which you move to randomly chosen addresses in your storage system.
Retrieving items in a fixed combination is a task in process flow split activity. You have four classes by different amount of products by class, then you split your initial token into four siblings. Those are calling a run sub flow process to retrieve as many randomly storage items as needed. This sub process can also be responsible to control workers or it creates tasksequence, which are pushed to a list. You pull best suited tasksequences from this list to optimize worker runs.

Thanks for responding. I am new to this software and this is my first project. You mentioned that retrieving the items in a fixed combination is a task in the process flow split activity. Could you clarify this a bit? How can I do this?

You need to make a global table to record your order, the combiner can get the order quantity information by label ,
