Upload a List with System Managed Fields

[Anonymous]

I have a list that I exported and need to import back into Marketo. There is a system managed field on the list, I need to update. Is there any way to bypass the "Blocked (System Managed)" and update the field?

Which field is blocked? If it's Lead Owner, you can't update that field directly. You would need to use Lead Assignment Rules or update another field that has a Trigger to change the Lead Owner.

System fields cannot be updated by a user at all.
