Error messages when generating FMT files in F10G

Hello All,

I'm migrating an application from 6i to 10g, currently.

I've been facing some issues but, step-by-step, I've been able to go ahead, except for this case:

I've could compile a big form (2.55MB), save it and generate the FMX executable file, but when I attempt to generate the FMT file, fails:

first: ROS ERROR: -500 message

second: FRM-10044: Cannot create file.

These message are displayed as Forms Builder as Forms Compiler tools.

Others compiled forms for this 6i application don't have this kind of issue when compiling and generating files (fmb,fmt,fmx), that's why this is rare to me for understanding.
