Unable to use DBI item: BEN_PHB_STUDENT_STATUS in Dependent Eligibility Type

Summary:

Content (required):

We are using a fast formula of type ‘Dependent Eligibility’ to set dependents of type ‘Child’ and whose Student Status is either ‘Full-time student’ or ‘Part-time student’ to be eligible for a certain Catastrophe Cover.

We identified the DBI item ‘BEN_PHB_STUDENT_STATUS’ to be storing the information we need. But we are unable to know what data is being stored in the DBI.

We have not seen any documentation about how to use it. Can you please let us know how we can use this DBI?

Please find attached screenshot of the field we need and the Fast Formula.
