What are the journal entries generated for an invoiced sales order shipped from a different BU?

Summary:

I have created Sales Order from Business Unit A

Goods have been shipped from an organization in Business Unit B.

The Invoice was finally accounted for AR and posted to GL for Business Unit A

What are the journal entries generated for this process? This customer uses this dropship process but does not generate POs or Intercompany Invoices, what is the best recommendation for this case? Both the process ad setup required

Content (required):

In this case, the customer doesn't want to generate an intercompany PO or Invoice.

The goods are transferred at cost, with no margin added

The need is to reflect the transfer of goods from Business Unit B to Business Unit A in the accountancy, but the goods from Business Unit B are shipped directly to their customer.
