When creating an extension field (KUT) "Global Data Type" (GDT) and selecting the sub type as "Country/Region Code" it only appears Country as the dropdown value. You would like to add Region as dropdown value too.
SAP Cloud for Customer
This is current system behavior. Only country code is offered under global data type field. Region code is not offered.
This feature is not supported in the current release of SAP Cloud for Customer.
