I am showing only 3 hidden columns. When mapping, it appears that only the Contact(Primary Key) is selected for import. The other two: (Do Not Modify) Modify On and (Do Not Modify) Row Checksum do not have correlating fields to map to? I exported only the First Name, Last Name and 2 custom fields to update approx. 5000 records but continuously errors out.
Error: A record with these values already exists. A duplicate record cannot be created. Select one or more unique values and try again.
I do not the “use for import” selecting as I have seen for CRM2011 tutorials.
Is there any documentation on the export/re-import into CRM??? It seems that this should be able to be done. Please advise. Thank you!
