I have synchronized the Leads created in Salesforce with a Data Extension in Marketing Cloud.
I want to update the value of my DE
Y, if I find a record in my synchronized DE which has a common record to the DE
I consider the records to be common if both have same
Edit:- I tried to filter the synchronized DE on Automation studio, but I am unable to see any record on the journey builder. Furthermore, I tried to manually create a filtered DE and then add it to the Journey Builder, but the Journey Builder doesn't reflect any update I make to my DE after it (the Journey Builder) is started.
