AEP - update profile attribute conditionally
Hi
I have a question about the possibility to update a certain profile attribute under some conditions.
Let's say I have a profile attribute called "Last Touchpoint". If the attribute is populated in the profile, I don't want to overwrite it with the value coming from a batch ingestion for a certain source. In other words, I want the value already in the profile to trump any value coming from a certain source, unless the attribute in the profile is empty, but the data source has value.
Can this be achieved? Any suggestions?
Thanks.
