Error while updating hijrah end date

Hi,

I have a requirement to update employee's extra information. I need to update Hijrah end date.

Date format = '1440-06-04'.

When I try to update this field via API hr_person_extra_info_api.update_person_extra_info.

Column = p_pei_information3.

I am getting error like 'Hijrah Date format should be YYYY/MM/DD'.

I tried to_date and to_char to convert. but no use.

Thanks,

Venkatesan R
