Generating Log Statements

I am having problems with the Post Mass Retirement process.  I notice in the PL/SQL code that there are several places where useful information would be written out, e.g.

      if (g_log_level_rec.statement_level) then
         fa_debug_pkg.add(l_calling_fn, 'px_max_mass_ext_retire_id', px_max_mass_ext_retire_id,g_log_level_rec);
         fa_debug_pkg.add(l_calling_fn, 'p_book', p_book_type_code, g_log_level_rec);
         fa_debug_pkg.add(l_calling_fn, 'p_parent_request_id', p_parent_request_id,g_log_level_rec);
         fa_debug_pkg.add(l_calling_fn, 'p_total_requests', p_total_requests,g_log_level_rec);
