Can't create Work Order for Process Manufacturing

Summary:

Hi, I created a new Org, Items (Item Type = Formula), Ingridients, created item structure and I could create a Work Definition for the primary item. Now when I try to create a Work Order, I receive the error message:

"There are no meterials for the operation (WIE-4426410). Details: At least one material that contriubtes to yield and has the push supply type is needed for a work order with batch quantity type as Calculated."

I could change the supply type to "Push" but "Contribute to Yield" filed is read-only.
