You are using OData API to query "incumbent" field from Position, but no values return from it, even though you are sure that the Position has an incumbent.
- SAP SuccessFactors HXM Suite
- OData API
If "Position Management" feature (in Admin Center > Manage Employee Central Settings) is enabled in your SF instance, then it would be expected for incumbent field to return a blank data.
When such feature is enabled, you should query the incumbent information via EmpJob (Job Info) entity, as the Job Information segment of an employee would hold the information about which position the employee is assigned to.
