can someone help with including attributes in the tracking extract output?
My goal is to include in the tracking extract an internal list id that corresponds with a subscribers' event. That list id is added to the file generated by our EDW then imported into a DE.
I select "Extract Attributes" then define the attribute I want included in the free-form field. When I run the extract I get the Attributes file and the attribute I've defined is the column header, but the column is empty.
What I'm looking for is to include that attribute in the other files in the extract to then be ingested into our EDW for reporting purposes. So for example each record that was sent would have an "InternalListID" attribute column and the column would pull the InternalListID from the DE and append it to the file; same for bounces, opens, clicks.
Based on the Tracking Extract and Attributes documentation, I feel like that should be the expected outcome, but so far it is not. Am I doing something wrong or is that functionality not what I think it is.
