### About Using Combo Boxes

Do not use combo boxes for validating business objects that have a large number of rows. The maximum number of rows a combo box can display is 200. If there are more than 200 rows, the system does not return the excess rows. If a business object has more than 200 rows, we recommend using a text box with a **Search** dialog box.

To effectively validate business objects with more than 200 rows, perform one of the following:

- Change the business object from a combo box to an associated item selector. Access this function from the field control toolbar.
- Constrain the combo box field to validate using another field to reduce the number of rows returned. For example, constrain the **Employee** field to be constrained by the **Department** field, so that when validating the **Department** field, only employees from the department selected are shown.

### Creating a Pick List

1. From the Configuration Console, click **Build > Pick Lists** to open the **Pick Lists** workspace. The system displays a list of pick lists.
2. Click **Add New\...**. The system displays the **Add New Validation List** page.
3. Enter information into the fields.

| Field              | Description                                                                         |
| ------------------ | ----------------------------------------------------------------------------------- |
| List name          | The name of the pick list to be stored.                                             |
| Display name       | The name of the pick list to be displayed in Ivanti Service Manager.                |
| Get list data from | Check Business Object and select a business object from the drop-down list.         |
| Display field      | The name of the field to display in the pick list.                                  |
| Value field        | A stored field name. Select from the drop-down list.                                |
| Sort by field      | The field by which to sort. Select a sorting value, either ascending or descending. |

4. Add constraints to the pick list to restrict the data presented. Click the **add new** icon to add a constraint formula. This formula is based on the parameter selected in the **Get list data from** field.
5. Click Save.

See the Ivanti Service Manager online help for additional information about creating and modifying a pick list and its values.
