Data extensions used in Journey builder - how to append data

Question

During my Journey the data extension fields are getting updated with information that is then used in the decision splits : 5 fields reflecting the links on which the customer has clicked for ex in the Data extension, I need a field that concatenates all this information so a field that is "appended" regularly during the journey so I can then use it to populate the description of the lead

Is there a way to append data to a field already containing information in the Data extension? update customer seems to replace but not append Is this something where I would need an SQL query and automation studio or is there a simpler solution ? thanks

Answer 1

Yes you can use data binding syntax to update data extension field

1. Let's say the field in your Journey Builder Data extension is called "logs"
2. Go to Entry Source tab, click on the entry source, take a note of Event Definite Key, for example: Event123456
3. Use below syntax in "Update Contacts" tile, separate by a space, "ExtraDetails" is the new content you want to "append" to the field:

{{Event.Event123456.logs}} ExtraDetails

Once it is executed in the Journey, you should see it is updated in the DE row.
