I have a sync data extension and I want to update records in All Subscribers. I've completed these steps using automation:
- Data Extract Activity;
- A File Transfer Activity to put the file in FTP;
- An Import Activity to import the subscribers list in All Subscribers.
My DE has these fields: Subscriber Key, Email Address, Status and the other fields are renamed exactly like the fields in All Subscribers. But I see this error Import Activity: InvalidRestrictedFieldValue
Any solution on this?
