Magento 2 – Can’t Buy Product Due to No Source Items in Stock

configurable-productmagento2magento2.3magento2.3.2

If I try to buy a product, then I get "There are no source items with the in stock status" and "This product is out of stock."

enter image description here

So I opened the product and noticed that the Quantity is set to 0 and grayed out.

enter image description here

If I click on the link text "Advanced Inventory" and enter a value to Qty e.g. 1000 and press on Done and then on save, then it is 0 again after it saves.

What is going on?

Best Answer

I figured it out, I have to open all simple products which are connected to the configurable product, then go to "Advanced Inventory" and check the checkbox 'Use Config Settings' under "Manage Stock"
