# Suppress output

Specifies fields to exclude from the extraction output. For example, if you use the field ID `_raw_data` as a source for a [computed field](/senseml-reference/computed-field-methods/index-computed-field-methods), then specify the raw field's ID in this method to show only the computed field in the output.

## Parameters

The following parameters are in the computed field's [global Method](/senseml-reference/computed-field-methods/index-computed-field-methods#parameters) parameter:

| key                        | value                                    | description                                                                                                                                                                                                                                                                                                                       |

| id (**required**)          | suppressOutput                           |                                                                                                                                                                                                                                                                                                                                   |
| source\_ids (**required**) | array of field ids in the current config | The id of the fields to exclude from the extraction output. In advanced use cases, configure [field execution order](/senseml-reference/concepts/field-order) to prevent unintential null output from other computed field methods. For an example, see [Zip sections example](/senseml-reference/sections/sections-example-zip). |

The following example shows suppressing a raw "driver's name" field and outputting the split last name.

**Config**

```JSON JSON 
{
  "fields": [
    {
      "id": "_driver_name_first_last_raw",
      "anchor": "name of driver",
      "method": {
        "id": "label",
        "position": "below"
      }
    }
  ],
  "computed_fields": [
    {
      "id": "driver_name_last",
      "method": {
        "id": "split",
        "source_id": "_driver_name_first_last_raw",
        "separator": " ",
        "index": 1
      }
    },
    {
      "id": "hide_fields",
      "method": {
        "id": "suppressOutput",
        "source_ids": [
          "_driver_name_first_last_raw"
        ]
      }
    }
  ]
}
```
