I have created a Journey where the entry event is a Salesforce Data extension and a contact is injected into it when he creates a new record in an object named Application. When it happens, the information regarding the percent completed of the application is saved in the Journey Data Extension and, after a specific date, the system sends an email with this information (using personalization string).
My issue is that I need to map Contact Data and not Journey Data because at the begining, the percent complete is 0%, but when the email is sent the percent complete may be 50% (as an example) and I need this data updated.
How I should change the personalization string in order to map Contact Data instead Journey Data?
