Step 3 You must add a unique Name for your Stock. Other than that, in Sales Channels, you can assign the stock to one or more listed sales channels. The sales channel is (mostly) your Magento views.
Step 4 Then Assign Sources. Choose the sources you want to apply to the new stock. Then, click Done.
Step 5 Save.
The main difference between Sources and Stocks is that Stocks can be deleted.
Stocks can’t be disabled, however, any sales channels and sources can be reassigned as needed.
If you don’t want to delete a Stock, you can choose to edit it.
You can change everything, from the Name, the sales channels, and the assigned sources.
But remember that you can only do it with New Stocks, not the Default Stock.
Also, if you unassign a sales channel without adding it to another custom stock, it will be assigned to the Default Stock.
