Workday API Security Gotcha's

Validation error occurred. The entered information does not meet the restrictions defined for this field. (Replacement_for_Worker_Reference).

I was working with the Edit_Job_Requisition API and kept hitting this error; even though I wasn't touching the Replacement_for_Worker_Reference at all in my API request.

Solution: give the ISU View access to Worker Data: Public Worker Reports. I wasn't missing any job requisition related security, I was missing the security to see the worker in the Replacement_for_Worker_Reference. Imagine completing the task through Workday's UI, I couldn't see the drop down list of workers without that domain.
