Get Promotions applied to a lineItem

Hi team,

          To obtain promotions available for a particular lineItem, we used the following code

       var allPromotions = promotionEngine.Evaluate(contentLink, currentMarket.GetCurrentMarket(), Currency.USD, RequestFulfillmentStatus.PartiallyFulfilled | RequestFulfillmentStatus.Fulfilled);

When the redemption limits are set to the Customer, the available promotions are not obtained. I have set the redemption limit as 5 and the number of orders placed to that order is 2 and still I am not able to obtain the promotions that are applied to a lineItem.

Thanks.
