# Managing Source Datasets

## Overview

A source dataset specifies which data to import from a source system. Each source dataset belongs to a connection, and a connection can have one or more source datasets. On the **Integrations** page, each source dataset is displayed as a child row of the connection it uses.

## Creating a Source Dataset

To create a source dataset, click the icon in the row of the connection you want to use to import data and select **Create new dataset**. Specify the following details, then click **Create**:

| Field | Description |
|---|---|
| Connection | Connection to the system the data is imported from. It is preselected and cannot be changed. |
| Name | Name that identifies the source dataset on the **Integrations** page. Required. |
| Namespace | Technical identifier for the source dataset, used to reference its data tables in SQL queries against the data lake (for example, namespace.table_name). It can have up to 255 characters and must be SQL-safe, with no spaces or unsupported special characters. After the first import, the namespace is locked and cannot be changed. Required. |
| Configuration | Data to import from the source system. For more information, see [Source Dataset Configuration](#source-dataset-configuration) below. Required. |

The source dataset is created and displayed under its connection on the **Integrations** page.

## Source Dataset Configuration

The configuration of a dataset defines which data is to be imported. The available options depend on the source system and reflect the data it can provide.

For an SAP S/4HANA connection, the source dataset configuration includes, for example:

- **Upload OData v4 entities**: Entities to be imported from the source system, for example an entity that provides general ledger balances.
- **Use fixed navigation filter 'Company'**: Option to restrict the import to a specific company.
- **Navigation filters**: Values used to filter the import, for example a specific company.

## Additional Options for a Source Dataset

You can manage an existing source dataset from the icon in the row of the source dataset on the **Integrations** page. The following options are available:

| Option | Description |
|---|---|
| Start import | Option to start an import for the source dataset. For more information, see [Importing Data](https://support.lucanet.com/en/documentation/data-hub/importing-data.md). |
| View execution details | Option to display the execution history of the source dataset. For more information, see [Importing Data](https://support.lucanet.com/en/documentation/data-hub/importing-data.md). |
| Edit | Option to change the name, namespace, or configuration of the source dataset. |
| Deactivate / Activate | Option to set the source dataset to **Inactive** or back to **Active**. An inactive source dataset cannot be imported. |
| Delete | Option to delete the source dataset. |
