POXPOVPO form fails with Error after migration.

 

Hi All

We migrated Oracle eBiz R12(12.0.6) from AIX 5.3 to AIX 6.1, when we try to generate forms, POXPOVPO.fmb unable to generate forms.Version of the fmx is same on both PROD and TEST.

While compiling the form it fails with 

FRM-30064: Unable to parse statement select  nls_language,language_code from fnd_languages fl ,po_vendor_sites_all pv  where
fl.nls_language  = pv.language and pv.vendor_site_id = :headers_folder.vendor_site_id
union
select nls_language ,language_code  from fnd_languages fl where
fl.language_code = userenv('LANG').
