To produce 6 packs of Product A, I need 1 Giant Sheet.

So if I have 3 Giant Sheets, I need to forecast that I can produce 18 packs of Product A.

It's similar to available to promise (ATP). Product A is made to order, so it never has stock on hand. A customer might ask the owner how many packs of Product A they can produce with the available Giant Sheets.

Manually, they check the available Giant Sheets on hand. So if I have 3 Giant Sheets, 3 * 6 = 18.

But they want to forecast this without manually computing it.

How can I project this in Odoo, either using the Inventory app or the Manufacturing app?
