protected override RewardDescription Evaluate(EntryPromotion promotionData, PromotionProcessorContext context)
{
  var lineItems = GetLineItems(context.OrderForm);
  var condition = promotionData.Condition;
  var applicableCodes = targetEvaluator.GetApplicableCodes(lineItems, condition.Targets, condition.MatchRecursive);   
  var filteredLineItems = GetFilteredLineItems(lineItems, condition.RequiredQuantity);  
  var filteredApplicableCodes = GetFilteredApplicableCodes(applicableCodes, filteredLineItems);                

  if (applicableCodes.NotNullOrEmpty() && filteredApplicableCodes.IsNullOrEmpty())
  {
    return RewardDescription.CreatePercentageReward(
      FulfillmentStatus.PartiallyFulfilled,
      Enumerable.Empty<RedemptionDescription>(),
      promotionData,
      promotionData.Percentage,
      Enum.GetName(typeof(RequestFulfillmentStatus), RequestFulfillmentStatus.PartiallyFulfilled));
  }  

  var fulfillmentStatus = fulfillmentEvaluator.GetStatusForBuyQuantityPromotion(
    filteredApplicableCodes,
    filteredLineItems,
    condition.RequiredQuantity,
    condition.RequiredQuantity);

  return RewardDescription.CreatePercentageReward(
    fulfillmentStatus,

我们已定制促销，仅对需要数量的订单项应用促销。现在，当我们从其他促销中排除促销时，并且两个促销项都适用于这两个促销时，则只有一项促销同时被应用。

例如：我们希望应用一个订单项“购买10个项目并获得10％”，而其他订单项应用“购买20个项目并获得20％的出价”。

如果它是适用于促销的单个订单项，则效果很好！ （我们正在使用Commerce 12.5.1）

感谢您的答复。

我们通过使用受影响的条目来实现了解决方案。

  ////To check applied discount entries.
        var isPromotionApplied = context.EntryPrices.Prices.Count() > 0 ? true : false;
        if (isPromotionApplied)
        {
            ////To filter the item if it have already discount.
            var codesAlreadyDiscounted = context.EntryPrices.Prices.Select(x => x.ParentItem.Code);
            lineItems = lineItems.Where(x => !codesAlreadyDiscounted.Contains(x.Code));
        }
