I am developing an email that will send using a specific data schema, but I do not have that schema in my sandbox. I am wondering if the correct flow for this would be to start a workflow -> call the data schema in question -> populate the variables - but how would I populate the data schema with the data I need for the send?
Also, is there a way to do this as a proof or individual send? Or do I have to run a workflow in order to call the schema in question?
Once done, you can import in a workflow a CSV file to insert/update required columns in the "data schema" and then use a query activity to select it in order to target your delivery population
But... That's the technical aspect, for my part, as you could use directly the CSV file with an import activity and use the existing "mapAny" target mapping. Is there any special requirement to build a dedicated schema?
