How can I set Source Priority for Source Selection Algorithm in Magento MSI (Multi Stock Inventory)?

Question

I have been exploring MSI. I came across the "Source Selection Algorithm" when creating a shipment.
It has two options:

1. "Distance priority"
2. "Source priority"

When I select "source priority" nothing happens.

Where and how can I set this priority?
The order of the sources is set when we created the Inventory stock (Stores > Inventory: Stocks)

Answer 1

you can set-up priorities of Sources in the scope of the given Stock on that Stock editing page in Admin panel or via Web API.

Here you can read more about that: https://github.com/magento-engcom/msi/wiki/Create-Stock (Assigned Sources and Priorities - section).

After adding sources to the stock, arrange those sources from top-to-bottom in priority for fulfilling orders using Drag-n-Drop. The Source Selection Algorithm (SSA) provides an algorithm Priority using this order when determining shipment and inventory deductions.
