I'm trying to import region data into a flat file in the given L2 data hub model. while doing so I'm getting some error saying "Invalid Code". I have attached the screenshot of source data and all the steps for the same. Any help in this regard would be helpful.
Moreover, I want to understand when my source data has 2 columns why during the mapping there is three fields, and what exactly to be added in the property list named Region Flat.
