Populating Statutory Information with an API

Good Day All ~

I have a need to be able to populate information on the Statutory Information via the use of an API.  These records to be updated are for new employees and this is part of creating their new assignment records in Oracle.

I think I can use the following API to do so but some confirmation would be good right off to make sure I am not starting off completely wrong.   I think I would be passing information into the p_concatenated_segments attribute.

hr_assignment_api.update_emp_asg_criteria

If I have the three fields I wish to pass into it what would the format need to be?  For example, I need to populate the GRE, Timecard Approver and Timecard Required fields.  So can I pass something that is delimited by a pipe symbol?  That is how the data is coming from the originating system.  GRE|Approver|TCReqd.
