Use of Sales Employee in HR and SD

Hi

We have this scenario in our company.

1.A Employee is hired using the HR module and h gets a personnel number.2.we maintain infotype 0900 "Sales Data" for this employee here we

select his Sales Org , Sales Office , Sales Group.

3.We want to send some samples to this employee on his communication

address maintained in HR by creating a sales order in the SD module.

4.i tried various search in this site and other forums to find out how

a employee can be used as a customer but was not able to find much.

5.Request your help to tell me how to use a employee hired thru HR in

the SD module for order creation etc.Please send/direct me to documents if

available.

regards
