Problem summary

• USERS AFFECTED:
  Websphere Commerce V7 customers who wish to have multiple
  promotion codes applied for the same promotion through
  customization.
  
  PROBLEM ABSTRACT:
  Enhance promotion engine to allow customization for applying
  multiple promotion codes for the same promotion.
  
  BUSINESS IMPACT:
  Promotion engine cannot be customized to allow applying multiple
   adjustments for the same promotion through redemption of
  promotion codes.
  
  RECOMMENDATION:
  

Problem conclusion

• Exposed a new protected method computeCostBasedDistribution in
  the Distribution class. This method can be extended and called
  multiple times, once for each time the promotion needs to be
  applied.
  
  A new value was added into the Promotion interface called
  codeCouponPerOrderLimit which controls how many codes can be
  applied for the same promotion.  By default this value is 1 for
  compatibility with existing promotion logic and must be set
  through customization.
  
  New methods were also introduced in the PromotionContext to
  retrieve all the codes the shopper has applied: getCodesFor
  which returns all codes added that relate to a particular
  promotion, and getAppliedCodesFor which returns the subset of
  added codes which could be applied for a particular promotion,
  up to the codeCouponPerOrderLimit.
