Can I use the source organization's business unit for sales orders created from transfer orders?

Yes, when using Supply Order Defaulting and Enrichment Rules to route transfer orders through Oracle Fusion Cloud Order Management, you have the option to align the sales order requisitioning business unit with the source organization's business unit.

Normally, when you create a sales order from a transfer order, you use the destination inventory organization's business unit on the sales order. Creating the sales order in the source organization's business unit lets the organization actually shipping the requested goods accurately track the internal order through its lifecycle. This also enables you to accurately manage and account for orders through their lifecycle.

In the case of multiple lines and source organizations, the first line of the transfer order determines the business unit on the sales order.
