We want to update contact in our Journey. The data extension A enters the journey and it has "UNIQ_ID" column linked to Contact Key in Data designer. In the journey, we want to update "Flag" column in data extension B. Data extesnion B also has "UNIQ_ID".
Should Data extension A and data extension B be linked by "UNIQ_ID" in Data designer for this? Is there anything else we need to do ? I have set "record Date" field in data extension B to "Current date" to capture record date. Will it update everytime we update the contact ?
