I'm Trying to Import Salesforce Data to Marketing Cloud using Import Activity. But that's cannot work with marketing cloud. and I've refered following document : https://help.salesforce.com/articleView?id=mc_co_salesforce_data_extensions.htm&type=5
Create Report that include Contact ID, LastName, FirstName, FullName, Email based on Contact Object and save report Marketing Cloud Admin Folder.
Move to Interaction -> Import in Marketing Cloud and Click the Create Button.
Enetered Name Column and Select Salesforce Report on File location, Find previous Created Salesforce Report.
Select Overwrite Option on Update Type And Click Save.
going back to the previous page, Check Created Import Definition and run.
that Import Definition has Import Fail error occured.
What is I missing of those steps?
