11i ir R2 : How to generate a FMT file for an E-business Suite form

Hi,

For debugging purpose, I would like to generate a fmt file for E-business Suite Form.

For 11i I'm trying :
f60gen module=$AU_TOP/forms/US/APXINWKB.fmb userid=apps/... batch=yes forms_doc=yes module_type=FORM output_file=/tmp/TEST.fmt

But it never succeeds and no FMT generated.

Do you have the correct syntax ?

What is the instruction for R12 ?

I tried this document : How to Create Text Files from Many Forms that also Shows the PL/SQL Code within It in Batch Mode. (Note 731545.1)

but still no luck.

Regards,
Eric.
