I am currently needing to update one of my attributes in All Subscribers with the same attribute that currently lives in one of Master Data Extensions. I have created the attribute in All Subs but don't know how to go about refreshing or duplicating that data into its attribute in All Subs.

Any ideas please?

Try this

  1. Extract the master DE using a data extract activity
  2. Transfer it into the export folder in your FTP using a file transfer activity.
  3. Transfer it to in the import folder using another file transfer activity.
  4. Import it back into the all subscriber list using an import activity.

If this is a an activity you want to repeat, you can configure an automation to include all these steps in Automation Studio

Another option would to copy the file from the FTP location on your computer and import it from there. This negates the need for the second file transfer activity.

  • +1 Data_Kid. You can also do this manually by extracting the data to the FTP, saving to your PC/desktop, and importing manually. Slightly less steps if you don't have the File Locations and Transfer Activities set up. Mar 27, 2017 at 22:35
