Stacking rules and categoriesSome of the settings in categories are affected by stacking settings.Read Stacking rules to learn more about particular settings.
Create a category
You can create a category from the Stacking rules view by clicking Create category.Set hierarchy
In Hierarchy, enter a number.The hierarchy number helps define category priority when campaigns are applied together. A lower number means higher priority. For example, a category with hierarchy 1 is treated as more important than a category with hierarchy 2.The hierarchy number is displayed next to the category name in the Stacking rules view.
Categories are applied according to hierarchy only if Hierarchy priority is selected in Incentive application order in Stacking settings.
Configure stacking eligibility
Stacking eligibility defines how campaigns assigned to this category behave when they are validated together in the same redemption.This setting controls how campaigns from this category interact with campaigns from other categories.Choose one option:
-
Common: Campaigns follow the application order. They:
- Stack with other Common campaigns.
- Stack with Always stackable campaigns.
- Do not stack with Never stackable campaigns.
-
Never stackable: Campaigns in this category block Common campaigns in the same redemption stack. They:
- Do not stack with Common campaigns.
- Stack with Always stackable campaigns.
- Stack with other Never stackable campaigns.
Never stackable campaigns can be applied together only if the global limits in stacking settings allow it.
- Always stackable: Campaigns in this category always join the redemption stack if they are valid. They:
- Stack with Common campaigns.
- Stack with Never stackable campaigns.
- Stack with other Always stackable campaigns.
Configure no effect behavior

- Default: Uses the global No effect setting.
- Prevent redemption: The campaign is redeemed only if an effect was calculated.
- Force redemption: The campaign is redeemed even if it has no effect.
Configure discount calculations
In Discount calculations, choose how discounts are calculated:
- Default: Uses the global discount calculation setting.
- Initial: Calculates the discount from the original order value.
- Discounted: Calculates the discount from the current order value after previous discounts are applied.

It cannot exceed the global setting.
The global maximum value is 30.
