Payment using reward points not showing up on checkout in Magento Enterprise Edition -

i working on project in magento enterprise edition , need use reward points system in site. set reward points system in admin panel , allowed customer 260 reward points. when tried checkout, purchasing product using reward point not shown.

normally heard coming under payment option while doing checkout. in case not working. have enabled reward points , think have entered necessary settings. might missing or should solve problem?

quick-answer: set 2 reward exchange rates: from points money , from money points

for long time tried resolve issue. found problem here:

    if (!$helper->gethasrates() || !$helper->isenabledonfront()) {         return false;     } 

and $helper->gethasrates() returns false, because:

    $hasrates = $rate->fetch(         $groupid, $websiteid, enterprise_reward_model_reward_rate::rate_exchange_direction_to_currency     )->getid() &&         $rate->reset()->fetch(             $groupid,             $websiteid,             enterprise_reward_model_reward_rate::rate_exchange_direction_to_points         )->getid(); 

i checking 2 params. people ** come it...
