Item Master standard form customization

 Hi,

I need to customize item master form and to do so, while opening the form in forms builder 10g, I am getting following error:

FRM-18108: Failed to load the following objects.

I have picked up the complete resource directory from $AU_TOP to my local machine, mapped the directory (local machine) in form_path (regedit) as well. But still the form is unable to load certain objects. I am working in R12 instance, and using Oracle Forms version # 10.1.2.0.2.

Following is the details of error with the missing pll:

FRM-18108: Failed to load the following objects.
