Updating Task Owner using an import scenario

Hi, instead of hard coding the owner’s name in there, have you tried creating a column for owner in your source file and fill that column with the owner’s name? And then your source/field value will just be ‘Owner’? 

I have run into a similar error before and that’s what I did.

This is solved issue is for importing owner on a different screen but maybe it could be helpful

I would welcome any other thoughts on how I might work around this issue.

Thanks for that sample import scenario but it still throws the “Summary cannot be empty” error for changing the ownership of a task. Not sure where this error is coming from because the summary isn’t empty.
