lead source blocked during list upload

[Anonymous]

Hello,

When uploading a list to marketo, everytime i assign a 'lead source' field, it is highlighted in green and says it will be ignored from list upload. 

I looked in my field management settings and couldnt see it blocked from upload so im not sure exactly what is going on.

Any help would be greatly appreciated.

Thanks!

Hi Jeff,

Have you spot checked some of these leads? Usually what this is, is that your instance is set up to block lead source updates IF the field is already populated in the system. If the lead is new, it should pull in the value from your spreadsheet.

If you go to admin > field mgmt > search for and drag in lead source > then you can block updates from there.
