HDL - Update Supervisors for employees when current supervisor value is NULL

Summary:

Content (required):

Hi - I have successfully been able to update matrix managers for employees by passing the existing and new manager details in the Worker.dat HDL

However, for records that do not have an existing matrix manager, leaving the existing manager details blank in the HDL file throws an error when trying to upload.

Is there a way to update managers for employees when an existing value of the same supervisor type does not exist ?

Thanks
