Which Inventory screen should you use to configure the Inventory Adjustment Code in Oracle WMS Cloud?

Your customer is a Third Party Logistics operator (3PL) and ships multiple customer's orders from two centralized facilities, one on each coast of the country.
How do you set up the Facility, Company, and User hierarchy in the system (in sequential order)?

You have a high demand item in the warehouse that you order from different vendors (e.g. copy paper). Each one of your vendors has its own item number and barcode for the item, and you have your own internal number for the item. You want to process fulfill orders using your internal number.
What should you do in order to accomplish this?

You want to wave three orders. Two orders had the same route number in the order header, and the other order didn't have a route number. You want to make sure the orders are assigned to the same load.
What should you do or check?

You are creating a standard report for a client to display LPN Numbers (for multi-SKU LPNs) and their associated items. The two data fields you have in your report are LPN Number and Item Code.
Identify what controls need to be set to create a sub-total for the number of items for each LPN.
