How to generate credit memo from sales order?

Summary:

Requirement: Create a credit memo as part of order orchestration (not directly in AR, but from sales order)

Content (required):

We have a requirement to have a credit memo generated from sales order. However, we cannot approach via referenced RMA as there is no original sales order against which RMA can be initiated. We cannot approach via unreferenced RMA, as we do not maintain price lists in Oracle, External application is source of truth for prices at time of order import using salesOrdersForOrderHub.
