# Selecting a destination

Before running a preparation, you need to configure the run. The first step requires you to select or add the destination dataset.

## Before you begin

This feature is available only with a Remote Engine Gen2 version R2024-06 or greater, or the Cloud Engine for Design. Make sure you restart your Engine first to enable the latest updates.

A current limitation makes it not possible to run a preparation to datasets based on the following types of connections:

* Amazon DynamoDB (Database)
* Apache Kudu (Database)
* Azure Synapse (Database)
* REST (Web services)
* FTP (File systems)
* Azure Event Hubs (Messaging)
* RabbitMQ (Messaging)

## Procedure

1. Click the Run button on the top right of the screen to open the parameters panel.
2. Select a destination type from the following options:
   * Existing dataset. Select the dataset you want to export the result of the preparation to from the list.

   * New dataset. Give a name to the new dataset and specify the connection it will be based on.

   * Source dataset. The dataset used as source for the preparation will be updated with the prepared data.

     Here is a list of the connections you can use when selecting Source dataset as the destination:

     * Amazon Aurora (Databases)
     * Azure Cosmos DB (Databases)
     * Delta Lake (Databases)
     * Google BigQuery (Databases)
     * MariaDB (Databases)
     * Microsoft Dynamics 365 (Business applications)
     * MongoDB (Databases)
     * MySQL (Databases)
     * NetSuite (Business applications)
     * Oracle (Databases)
     * PostgreSQL (Databases)
     * Salesforce (Business applications)
     * SingleStore (Databases)
     * Snowflake (Databases)

   * Direct download: The prepared data is exported to a local file.
