Need a working HDL template to update the grade on the Employment page

Content (please ensure you mask any confidential information):

Hi Team,
I have successfully mapped the new grade to the position using HDL, and I now want the updated grade to reflect in the employee profile under Person Management.
I created an HDL template to update the grade on the Employment page; however, I am encountering errors during the upload.
Does anyone have a working HDL template to update the grade on the Employment page, or can you suggest an alternative solution to achieve this?
Thanks
Rajat
