Northern Trail Outfitters (NTO) wants to implement an abandon cart Journey. The data for the journey exists in three separate data extensions (DE).
* The first DE is populated by web analytics data, and does not contain a Subscriber Key or Email Address value.
* A Customer Reference DE is updated daily and holds subscriber information.
* The third DE is populated by a file sent to the SFTP after five days if the customer has not purchased the abandoned items.
* The third DE will be used in the Journey for a decision split, and it does not contain a Subscriber Key or Email Address.
* If the web analytics file is empty, NTO does not want the automation to finish running.
