# DocumentReferenceService - Scoped, Global

The DocumentReferenceService API provides methods for managing document references within a target table, such as the Incidents \[incident\] or Knowledge \[kb\_knowledge\] table. You can use document references to associate information with a record.

This API requires the Document Management plugin \(com.snc.platform\_document\_management\) and is provided within the `sn_doc_services` namespace. For information, see [Document Services](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/servicenow-platform/document-services-landing-page.md).

The following APIs enable you to define and manage documents:

-   [SystemDocument](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/api-reference/server-api-reference/SystemDocumentBothAPI.md) – Define a document object.
-   [DocumentService](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/api-reference/server-api-reference/DocumentServiceBothAPI.md) – Add, update, or delete a document.

```

## DocumentReferenceService - addDocumentReference\(String docSysId, String targetTable, String tableSysId\)

Adds a document reference to a target table record.

|Name|Type|Description|
|----|----|-----------|
|docSysId|String|Sys\_id of a document record in the Documents \[ds\_document\] table.|
|targetTable|String|Name of the target table on which to provide a document reference.|
|tableSysId|String|Sys\_id of the target table record to which the document reference is to be added.|

<table id="table_x4z_2cg_tpb" class="returns"><thead><tr><th>

```

</td></tr><tr><td>

&lt;Object&gt;.message

</td></tr></tbody>
</table>The following example shows how to add a document reference to a record in the Incidents \[incident\] table.

```

var result = docReference.addDocumentReference("<docSysId>", "incident", "<tableSysId>");

gs.info(JSON.stringify(result, null, 2));
```

Output:

```
{
  "message": "Adding an entry to DocumentReference for the given docId to target table : incident, sysId : <tableSysId> is successful.",
  "status": "success"
}
```

## DocumentReferenceService - removeDocumentReference\(String docSysId, String targetTable, String tableSysId\)

|targetTable|String|Name of the table containing the document reference. This information is listed with the document in the Document References \[ds\_document\_reference\] table.|
|tableSysId|String|Sys\_id of the record from which the document is referenced. You can find related information listed with the document in the Document References \[ds\_document\_reference\] table.|
