I added a parameter in custom report as below

global $reports;

            $reports->addReport(RC_INVENTORY, '_inventory_conversion', _('Invetory Conversion'),
                array(    _('Start Date') => 'DATEBEGINM',
                        _('End Date') => 'DATEENDM',
                        _('Inventory Category') => 'CATEGORIES',
                        _('Location') => 'LOCATIONS',
                        _('Sales Folk') => 'SALESMEN',
                        _('Conversion UOM') => 'UOM',
                        _('Show Service Items') => 'YES_NO',
                        _('Comments') => 'TEXTBOX',
                        _('Orientation') => 'ORIENTATION',
                        _('Destination') => 'DESTINATION'));

The new Parameter is UOM

Then I added following lines in reports_classes.inc

case 'UOM':
                        return stock_units_list(_('Units of Measure:'), 'units', null);

But When I try to run report it gives following error

Unknown report parameter type:UOM
D:\xampp\htdocs\boxygen\includes\ui\ui_msgs.inc:14:    trigger_error('Unknown report parameter type:UOM','256')
D:\xampp\htdocs\boxygen\reporting\includes\reports_classes.inc:153:    display_error('Unknown report parameter type:UOM')
D:\xampp\htdocs\boxygen\reporting\includes\reports_classes.inc:103:    (BoxReports Object)->getOptions((Array[10]),'_inventory_conversion')
D:\xampp\htdocs\boxygen\reporting\reports_main.php:530:    (BoxReports Object)->getDisplay()

What am I missing?
