# Managing Connections

## Overview

A connection specifies the authentication settings Data Hub uses to access an external source system, such as SAP S/4HANA or Microsoft Dynamics 365.

You can manage connections on the **Integrations** page, which you open from the **Data Hub** in the main menu. The page lists every connection together with its source datasets: each connection is a parent row that you can expand to display the source datasets that use it.

The **Integrations** page is displayed as follows, for example:

Connections and their source datasets on the Integrations page

The overview table on the **Integrations** page provides the following information for each connection:

| Column | Description |
|---|---|
| Connection name, Number of associated data sources | Name of the connection and the number of source datasets that use it. |
| Source system | External system the connection is established to, for example SAP S/4HANA or Microsoft Dynamics 365. |
| Status | Status indicating whether the connection is active or inactive. |
| Created by | User who created the connection. |
| Import | Status of the most recent import of the connection's source datasets. |

## Creating a Connection

To create a connection:

{% stepper %}
{% stepper-step %}
In the main menu, select **Data Hub**. The **Integrations** page is displayed.
{% /stepper-step %}
{% stepper-step %}
In the top-right corner, click **Create new connection**. The connection form is displayed as follows, for example:

Connection form with the source-system selection
{% /stepper-step %}
{% stepper-step %}
Select the source system you want to connect to, for example **SAP S/4HANA** or **Microsoft Dynamics 365**.
{% /stepper-step %}
{% stepper-step %}
Enter the connection settings for the selected source system. For more information, see [Connection Settings](#connection-settings) below.
{% /stepper-step %}
{% stepper-step %}
Click **Create**. The connection is created and displayed on the **Integrations** page.
{% /stepper-step %}
{% /stepper %}

## Connection Settings

The connection settings depend on the source system you want to extract the data from.

### General Settings

The following settings are the same for every source system:

| Setting | Description |
|---|---|
| Connection name | Name that identifies the connection on the **Integrations** page. Required. |
| SEA Instance | Instance of the **Lucanet.Script Execution Application** ([SEA](https://support.lucanet.com/en/documentation/consolidation-financial-planning/basic-configuration-cfp/install-and-use-opsea.md)) that runs the connection. Required. |
| Description | Optional description of the connection. |

### System-Specific Settings

All other settings are specific to the selected source system and define how Data Hub authenticates with it. For example, an SAP S/4HANA connection additionally requires the following settings:

| Setting | Description |
|---|---|
| Language | Login language for the SAP system. |
| Host | Host name or address of the SAP system. |
| Instance number | Instance number of the SAP system. |
| Client | SAP client to log in to. |
| User | User name for the login. |
| Password | Password for the login. |

The connection settings for an SAP S/4HANA connection are displayed as follows, for example:

## Additional Options for a Connection

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

| Option | Description |
|---|---|
| Edit | Option to view and change the connection's settings. |
| Create new dataset | Option to define a source dataset for the connection. For more information, see [Managing Source Datasets](https://support.lucanet.com/en/documentation/data-hub/managing-source-datasets.md). |
| Deactivate / Activate | Option to set the connection to **Inactive** or back to **Active**. While a connection is inactive, it cannot be used for imports, and all its source datasets are inactive as well. |
| Delete | Option to delete the connection. You can only delete a connection which is not used by any source dataset. |

{% warning-box %}
When you deactivate a connection that still has active source datasets, you confirm the change, and the connection together with all its source datasets is set to **Inactive**. Activating a connection again does not automatically reactivate its source datasets. You cannot deactivate a connection or source dataset while one of its imports is running or queued.
