Summary:

Configuring SCFO to derive intercompany prices from order line EFF

Content (please ensure you mask any confidential information):

We have following sales order scenario with 3 lines. Sales order and pricing is done in external system and integrated to Fusion Order Management:

Line 1 shippable item A, sales price 0

Line 2 shippable item B, sales price 0

Line 3 non-shippable (billing) item C, sales price 100

There is a billing hold, which ensures that the order is not immediately invoiced to the customer after shipment, but only when customer accepted and billing hold is released.

Furthermore, there is the requirement to create intercompany AR/AP invoices between the shipping and selling business unit for which Supply Chain Financial Orchestration can be used. The requirement is to generate AR/AP invoices upon shipment for above order scenario.
