Cannot load some workers by HDL

Summary:

Content (required):

Hello experts,

I'm loading employees and contingent workers by HDL.

We have three types of contingent workers: Intern, Consultant and Temporary.

I can successfully load employee and Temporary workers while I cannot load Intern and Consultant.

The system returns the following error message:

The user person type information isn't sufficient to derive the system person type. You must enter the system person type.

What could it depend on?

Kind Regards,

Valerio
