R12.1.3 Implementing HTML Project Manager responsibility

Hi,
We currently use standard (core apps) based Projects Billing / Project Costing modules, but I am researching the HTML Project Manager responsiblity in R12.1.3.

I can see by drilling down to the "Project Manager Responsibility Main Menu" menu via this SQL:

/*##############################################################################
#   MENU TREE VIEW
/*############################################################################*/
           SELECT fmev.entry_sequence seq
                , LEVEL
                , LPAD (' ', (LEVEL - 1) * 3, ' ') || fmv.user_menu_name menu
                , LPAD (' ', (LEVEL - 1) * 3, ' ') || fmev.prompt prompt
                , fmv.menu_name
                , fmv.user_menu_name
                , CASE
                     WHEN fmev.function_id IS NOT NULL
                     THEN
                        (SELECT user_function_name
                           FROM apps.fnd_form_functions_vl
                          WHERE function_id = fmev.function_id)
