# append Parameters

When you define an append transformation in the dataflow JSON, you set the action attribute to `append` and specify the parameters.

This table describes the settings for the append node in the dataflow editor.

  
| Setting | Required? | Value |
| --- | --- | --- |
| Sources | Yes | Nodes in the dataflow that identify the dataset that you want to merge. |
| Allow disjoint schema | No | Select to allow appending of datasets with different schema. If this setting isn’t selected, appending datasets with different schemas causes the dataflow to fail. |

This table describes the input parameters for the append transformation in the dataflow JSON.
