A **Rule** is a reusable object that maps to a DEE rule used to evaluate or process something.

There are the following types of **Rules** defined by its scope:

* **AlarmManagement** - used for notifications operations.
* **BOMQuantityCalculation** - used for quantity calculations of **BOM Products** in Weigh & Dispense operations.
* **CertificationManagement** - used for Certification Management operations.
* **ConnectIoT** - used for Connect IoT operations.
* **EDC** - a rule that can be used in a **Data Collection** for a calculating a parameter.
* **EFC** - used for Electronic Failure Catalogue operations.
* **ExceptionManagementAction** - a rule which executes an action (manual or automatic) in a **Protocol** **Checklist**.
* **ExceptionManagementSource** - a rule which feeds the possible values for a parameter in an **Protocol**.
* **General** - a general purpose rule.
* **InspectionReducing** - rules to be used when applying **Inspection Plan** Reducing methods.
* **InspectionTightening** - rules to be used when applying **Inspection Plan** Tightening procedures.
* **KPIDataSource** - used for **KPI** calculations.
* **LaborManagement** - used for Labor Management operations.
* **MaintenanceManagementAction** - a rule which executes actions when managing Maintenance Management operations.
* **MaterialFutureActions** - used to maintain Future Actions for a **Material**.
* **MaterialManagementAction** - used for Material Management operations.
* **OrderManagementAction** - used for Order Management operations.
* **PrintableDocumentContextItem** - a rule which is used to calculate a variable in a **Printable Document**.
* **PrintingIntegration** - a rule for printing using a third party Printing System.
* **RecipeManagement** - a rule that can be used in **Recipe** for a calculating a parameter.
* **SamplingSelection** - a rule used to apply a **Sampling Pattern** to a **Material**.
* **SendAheadSelection** - a rule used when performing **Send-Ahead Run** scenarios.
* **ShiftPlanning** - an action to be called to validate a **Shift Plan** **Calendar**.
* **SmartTable** - an action that will be triggered by a change in a Smart Table..
* **SortRuleSetMaterial** - a rule which is used to sort the list of dispatch Materials from the point of view of the **Material**.
* **SortRuleSetResource** - a rule which is used to sort the list of dispatch *Resources* from the point of view of the **Step**.
* **SPC** - a rule which is used evaluate if some chart rules are violated or not.
* **SPCAction** - an action that will be triggered by SPC when a SPC rule is violated.
* **System** - system rules provided out of the box.
* **TaskManagement** - used for Task Management operations.
* **TimeConstraint** - a rule which is fired when a time constraint warning or limit is reached.

!!! info
	The DEE rules classification available for each Rule Scope is defined in the generic table Scope Classifications.

## System Rules

The system comes pre-configured with the following rules in several different scopes, listed on the [System Rules](system_rules.md) page.

## Sequence Of Steps

!!! info
	It is only possible to create user defined rules, which require a Dynamic Exception Engine rule

The necessary steps for correctly using a **Sort Rule** are the following:

1. Create the Dynamic Execution Engine rule.
2. Create the Rule.
