I did not create a reference user for internal candidate. I have run the report to generate the business partners. I have created new user id's for the internal candidates and assigned the role 'SAP_RCF_INTERNAL_CANDIDATE'.
I have created a reference user 'RCF_CAND_INT' now. I tried to run the report for the rest of the employees, and i dont see the reference user role getting assigned to the employee's existing user id.????????????
I have created reference user for external candidate and it is working fine .
