# CMDBDuplicateTemplateUtil- Global

The CMDBDuplicateTemplateUtil script include provides methods to add and remove de-duplication tasks to/from a de-duplication template.

For more information on de-duplication of CIs, de-duplication tasks, and de-duplication templates, see [Duplicate CIs remediation](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/servicenow-platform/de-duplication-tasks.md).

## CMDBDuplicateTemplateUtils - CMDBDuplicateTemplateUtils\(\)

Creates an instance of the CMDBDuplicateTemplateUtils class.

|Name|Type|Description|
|----|----|-----------|
|None| ||

The following code example shows how to call this method to create a CMDBDuplicateTemplateUtils object.

```

var dupTemp = new CMDBDuplicateTemplateUtils();
```

## CMDBDuplicateTemplateUtils - addTasksToTemplate\(String templateId, Array taskIds\)

Adds one or more de-duplication tasks to a specified de-duplication template.

This method overwrites any existing template values, but logs the previous values for each template in the system logs.

The following list describes scenarios where a task isn’t added to a template and is then marked as either skipped or failed:

-   The specified template isn’t in the published state. All tasks are marked as skipped.
-   The specified template is running. All tasks are marked as skipped.
-   The task isn’t in the open state. The task is marked as skipped.
-   The task isn’t compatible with the specified template. For example, the specified template might be created for Application Server Tomcat, but the specified de-duplication task is created for Linux Server. The task is marked as skipped.
-   The specified template doesn’t exist. All tasks are marked as failed.
-   The GlideRecord update for the template column on the task fails. The task is marked as failed.

|Name|Type|Description|
|----|----|-----------|
|templateId|String|Sys\_id of the de-duplication template to associate with the de-duplication task.|
|taskIds|Array|List of sys\_ids of the de-duplication tasks to associate with the specified template.|

## CMDBDuplicateTemplateUtils - removeTemplateFromTask\(Array taskIds\)

Clears the de-duplication template value in the specified de-duplication task records. By clearing this value, the association between a template and the task is removed.

The following list describes scenarios where the template value isn’t removed from the task record and is marked as either skipped or failed:

-   The de-duplication template associated with the task is running. The task is marked as skipped.
-   The task state is "work in progress" or the task isn’t found. The task is marked as skipped.
-   The GlideRecord update for the template column on the task fails. The task is marked as failed.

// Remove tasks from template
var taskIds = [];
