I am building a new journey where the entry source will be a contact object. I want to write back all journey activities for each record to a separate DE in Marketing Cloud.
I know I will need to link this DE in contact builder, to create and "Update Contact" activity in the Journey. How and where do I create this link to the DE? I do not want to break my present contact model build by linking my DE incorrectly.
Any help you can provide would be great!
