I have read through all the Magento documentation on Salable Inventory and still can not figure out how to update the salable inventory quantities. All stores and products show "No manage stock" after successfully uploading to Stock Sources. The only way I have been able to update the salable inventory is by manually opening each product in the Catalog -> Products screen and editing any value in Stock Sources. Then the Product Salable Quantity is updated with double or triple the value of the Stock Sources.
The Magento User Guide is useless as it does not identify the section of the Administrator that they are dealing with. If you know the menu inside out and backwards you might be able to follow the guide.
Is there a global setting that needs to be changed to get this working?
