We're trying to import a csv fial in a file-drop-to-our-FTP scenario and subsequent import file activity. We're keep getting this error sent by Marketing Cloud upon executing the automation: Results:
Inserted: 0 Updated: 0
Field Not Found: 1 Required Field: 530
Could a reason for this be that all the fields in the target data extension were set as "Text", and in our source csv files we have a lot fields formatted in Excel as "number", "decimal" and "postal code", or this does not affect Marketing Cloud?
