# Add Attributes to a Change Tracking Group (Master Data Services)
  In [!INCLUDE[ssMDSshort](../includes/ssmdsshort-md.md)], add attributes to a change tracking group when you want to track changes to the attribute's values.  
  
> [!NOTE]  
>  After you add an attribute to a change tracking group, when values for the attribute change, the attribute is flagged as changed in the [!INCLUDE[ssMDSshort](../includes/ssmdsshort-md.md)] database. Create a business rule to take action based on the change.  
  
## Prerequisites  
 To perform this procedure:  
  
-   You must have permission to access the **System Administration** functional area.  
  
-   You must be a model administrator. For more information, see [Administrators (Master Data Services)](administrators-master-data-services.md).  
  
-   Attributes must exist to add to the change tracking group. For more information, see [Create a Text Attribute (Master Data Services)](../../2014/master-data-services/create-a-text-attribute-master-data-services.md).  
  
### To add attributes to a change tracking group  
  
1.  In [!INCLUDE[ssMDSmdm](../includes/ssmdsmdm-md.md)], click **System Administration**.  
  
2.  On the **Model Explorer** 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.  Select the row for the entity that you want to track attribute values for.  
  
5.  Click **Edit selected entity**.  
  
6.  On the **Edit Entity** page:  
  
    -   If the attribute is for leaf members, in the **Leaf attributes** pane, select the attribute and click **Edit leaf attribute**.  
  
    -   If the attribute is for consolidated members, in the **Consolidated attributes** pane, select the attribute and click **Edit consolidated attribute**.  
  
    -   If the attribute is for collections, in the **Collection attributes** pane, select the attribute and click **Edit collection attribute**.  
  
7.  Select the **Enable change tracking** check box.  
  
8.  In the **Change tracking group** box, type a number for the group.  
  
9. Click **Save attribute**.  
  
10. On the **Entity Maintenance** page, click **Save entity**.  
  
11. Repeat this procedure for all attributes you want to include in the group. Use the same change tracking group number for each attribute in the group.
