There is a basic problem in the way you are calling the API.
While calling an API you need to take care of the effective date and date track mode. In this case, since you are using the date track mode 'CORRECTION', I suppose that you want to correct (and not update) a date tracked record for the person.
Now if you pass the effective date as sysdate, system will correct the record which is effective on the sysdate. Hence first you should fetch the object version number of that record and then pass it to the API as an IN OUT parameter.
So the modifications you need to do in your API call is as follows:
1. Always use function trunc(<your effective Date>) as input parameter for effective date while calling HRMS APIs.
2. In the code block, before calling the main API hr_update_api.update_person, write a select query to fetch the object version number for the record effective on the effective_date passed by you (in this case sysdate).
select object_version_number into l_obj_version_number
from per_all_people_f
where person_id = <person_id>
and trunc(sysdate) between effective_start_date and effective_end_date;
Use this l_obj_version_number for parameter p_object_version_number in call to the API.
I hope this should resolve your problem. Try it and do let us know how it worked out.
