I have a synchronized Object from Salesforce, connected to Marketing Cloud through the MC Connector. However, some of those fields are empty, and I want to fill them through a Landing Page I created in Marketing Cloud.
I did an automation with an SQL Query so as to fill a Local Data Extension that merges the data coming from the Landing Page with the data on the Synchronized Object stored in Salesforce, filling a local Data Extension.
However, now I need to send that data back to Salesforce so as to populate that object. How can I do it?
