We would like to upload the marketing channel cost with breakdown with Countries like below example,
I checked the documentation but it seems Countries is not a supported dimension (while State and Zip are supported). So would like to check with other folks here if they have experience on this? or other suggestion to achieve something similar?
The out of the box dimension "Countries" is not currently supported by Data Sources. So, my suggestion will be to use a custom variable like any eVar & use can that eVar to upload the data for the Countries.
