Spreadsheet data load error when attempting to update job title

Summary

Receive an error when attempting to update job title

Content

Hello -

Would appreciate any assistance if you have been successful updating employees job titles using spreadsheet data loader.

In my latest attempt, I receive the following error: "A parent for this record was not found. Use any of the four supported key-resolution systems to supply a valid parent reference.,"

I have work terms and assignment, so can't quite figure how to resolve this.

Thanks,

Jess
