Error message " You cannot Update an Expired Instance. Instance needs to be

Question

Hi,
I am trying to update Insatll base records in csi_item_instance table( like updating system_id value) by calling API csi_item_instance_pub.update_item_instance. I am getting error message " You cannot Update an Expired Instance. Instance needs to be un-expired before any updates". But actually instance is not expired and active_end_date field is null and instance_status_id=3(Latest).I am getting this error message for only some records.but for these records also x_return_status = S.
Please suggest what could be the reason.
Thanks in advance.
