Hi Craig,
You are welcome 🙂
The SKU can be displayed without additional code, by using the Advanced title or Content fields.
Basically, the product SKU is stored in the _sku custom field, so for example to display it before the search item description, you can use this syntax in the advanced description field:
[code][<strong>SKU:</strong> <i>{_sku}</i><br>]{descriptionfield}[/code]
This results the following output: https://i.imgur.com/bIRGrg9.png
