HSDL not working for Assignment update

Summary: HSDL not working for Assignment update

We have created attached HSDL template for assignment changes, but it keeps on erroring out with error message “You must provide a valid reference to the parent record. Ensure that the parent record is supplied in the same file or has already been created. You can reference the parent record using one of the four supported key types. The View Business Objects task lists the attributes that you can use to identify the parent record for this component.”

Please assist with a working Assignment update HSDL template.

Thank you
