I have a question regarding manufacturing at other Vendors. Here is the process that I am trying to recreate. I have grain which some is bought some is harvested, then this grain will be milled at another company and the milling will have a cost of milling and packaging. Then I have the final product the flour in bags.

I am able to create the manufacturing for the flour with the cost included, but it doesn't record the sending of the grain and receiving of the flour. Does anyone have a similar use case?
