Power Pivot/Query: Cumulative inventory based on future sales

Hi all!

This request is specifically for Power Query/Power Pivot.

I have two tables, one for inventory and one for sales.
The inventory table shows current inventory by warehouse and SKU.
The sales table shows sales that will be shipped in the future by SKU, warehouse, qty, ship date, and order #.

The goal is to build a pivot table that shows the following:

ROWS
Order #
SKU

COLUMNS
Ship date

VALUES
Current inventory
Qty on order
Net inventory (inventory after subtracting the qty on order and all orders with an earlier date)

I have attached a simplified version of my data as well as what the desired outcome would be.
