For more information, see [Administrators (Master Data Services)](administrators-master-data-services.md). - A model must exist. For more information, see [Create a Model (Master Data Services)](../../2014/master-data-services/create-a-model-master-data-services.md). ### To create an entity 1. In [!INCLUDE[ssMDSmdm](../includes/ssmdsmdm-md.md)], click **System Administration**. 2. On the **Model View** page, from the menu bar, point to **Manage** and click **Entities**. 3. On the **Entity Maintenance** page, from the **Model** list, select a model. 4. Click **Add entity**. 5. In the **Entity name** box, type the name of the entity. 6. In the **Name for staging tables** box, type a name for the staging table. > [!TIP] > Use the model name as part of the staging table name, for example *Modelname_Entityname*. This makes the tables easier to find in the database. For more information about the staging tables, see [Data Import (Master Data Services)](overview-importing-data-from-tables-master-data-services.md). 7. Optional. Select the **Create Code values automatically** check box. For more information, see [Automatic Code Creation (Master Data Services)](../../2014/master-data-services/automatic-code-creation-master-data-services.md). 8. From the **Enable explicit hierarchies and collections** list, select one of the following options: - **No**. Select this option if you do not need to enable the entity for explicit hierarchies and collections. You can change this later if needed. - **Yes**. Select this option when you want to enable the entity for explicit hierarchies and collections. In the **Explicit hierarchy name** box, type a name. Optionally, select **Mandatory hierarchy (all leaf members are included** to make the explicit hierarchy a mandatory hierarchy. 9. Click **Save entity**. ## Next Steps - [Create a Text Attribute (Master Data Services)](../../2014/master-data-services/create-a-text-attribute-master-data-services.md) - [Create a Domain-Based Attribute (Master Data Services)](../../2014/master-data-services/create-a-domain-based-attribute-master-data-services.md) - [Create a File Attribute (Master Data Services)](../../2014/master-data-services/create-a-file-attribute-master-data-services.md) ## See Also [Entities (Master Data Services)](../../2014/master-data-services/entities-master-data-services.md) [Explicit Hierarchies (Master Data Services)](../../2014/master-data-services/explicit-hierarchies-master-data-services.md) [Change an Entity Name (Master Data Services)](edit-an-entity-master-data-services.md) [Delete an Entity (Master Data Services)](../../2014/master-data-services/delete-an-entity-master-data-services.md)
