You are sending employees using the Business Partner Interface. 

1. You have to first do initial load of all employees using the dedicated idoc based interface (Basically, you have to filter the employees based on role in the DRF so that they are not sent out)
2. Then you have to load the employees using the business partner interface so that HCM identification id's gets created as external id's and a business partner id mapping as well is created
