HDL Assignment Change Error

Hello,

I am trying to load a HDL file to change the Person Type for employees, but I'm getting the following errors. I've included WorkTerms/Assignments and used the same effective dates, so it's not clear to me what the problem is. Any guidance would be appreciated.

The corresponding date effective record in the {PARENTNAME} for date {DATE}, action {ACTION}, and effective sequence {SEQ} is missing for the {CHILDNAME}.

The corresponding date effective record in the WorkTerms for date 2022-06-01, action ASG_CHANGE, and effective sequence 1 is missing for the Assignments.

Work terms records are required when you create or update assignments.
