Is there a way to automatically create a customer refund or cash refund from a credit memo? It does not seem to be available via CSV import and no transform action in the workflow. Is this possible only via scripting? Use case: I'm planning to import a credit memo and automatically create a customer refund or just import a standalone cash refund.

Help specifies what transformations can take place and you're correct there's none that would work for you so scripting would be the way to go. You could write a workflow action script if you already have a workflow working on the record. Alternatively a User Event or map/reduce, it depends on your specific use case.

Thanks @NElliott
