# Service

:lock: Service.**Show**

In the Critical Manufacturing MES model, a **Material** in a **Step** and context requires a **Service**. The context can be made of optional **Material**, **Flow** and **Product** combinations.

Services are, on the one hand, required by **Material**, and on the other, provided by **Resources**. Once a **Material** and **Resource** are both dispatchable and there is a match between the **Service** required and the **Service** provided, the **Material** can be dispatched to the **Resource**.

A **Resource** provides a **Service** that is requested via a **Step**, and a **Resource** may execute a variety of services. For example, an oven, which is a **Resource**, can bake, cook or grill, and at different temperatures, and these are different types of services.

A **Service** can also be an activity like painting, provided by a painting machine, which is a **Resource**. Additionally, if the machine has the ability to paint using different colors, these may be considered as different services, which may be used at different steps.

Additionally, when creating a **Service** the Processing Type field always refers to a **Resource**, so it is not possible to use a **Service** if you do not have a **Resource** that provides it.

!!! info
	Resource and Steps are associated through Services.

A **Service** can be enabled or disabled globally or at a particular **Resource**. When the **Service** is disabled, it cannot be used for dispatching purposes.

A **Service** has a **Service Context** view that provides you with the service resolution to be applied for a given **Material** at a **Step**.
