From where to get the return order number for SO without fulfillment

Summary:

We need a place where we can get the return order number for an original order number in case there is no fulfillment.

Content (please ensure you mask any confidential information):

Currently you can get the return order number from the page Manage Return Fulfillment Lines passing the **Original Order Reference field. However, we need to get the return order using the same mechanism but for orders without fulfillment lines.
