HDL for Assignment Change - Error

Summary

HDL file is erroring

Content

We have a number of employees who need to change assignment information due to a reorganization. The first test file was for the Assignment component (Worker object). When I loaded it, I had the following error:

A parent for this record wasn't found. Use any of the four supported key-resolution systems to supply a valid parent reference.
