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,
    GetRedemptions(filteredApplicableCodes, promotionData, context, lineItems),
    promotionData,
    promotionData.Percentage,
    fulfillmentStatus.GetRewardDescriptionText(localizationService));
}

我们已自定义促销，以便仅对具有所需数量的行项目应用促销。现在，当我们从适用于两个促销的其他和两个行项目中排除促销时，只有一个促销同时适用于这两个促销。

例如:我们希望一个行项目申请“购买10个项目，获得10%”和其他“购买20个项目，获得20%的优惠”。

如果它是适用于促销的单行项目，则可以正常工作！(我们使用的是Commerce 12.5.1)

谢谢你的回复。

我们通过使用受影响的条目实现了解决方案。

  ////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));
        }
