Unable to retrieve Planned PO

Dear all,

one of our user had erroneously created a planned PO instead of Standard PO from auto create  window,  now the problem we are unable to retrieve the PO from front end. I checked the status in the tables , its null as for incomplete status , I ran the script "poxrespo.sql" but the output is displaying "No PO with PO Number 'xxxx' exists in org 'xxx' which requires to be reset PL/SQL procedure successfully completed."  the status is null for that PO. please advice me to find the missing PO 

Regards,

Chico.
