# Start SAP Session‎

The **Start SAP Session** block is used to start a new SAP session for an existing connection when working with SAP GUI automation. It creates a session context that other SAP blocks can reuse in the same flow.

Fully expanded, the **Start SAP Session** block shows the following properties:

**Note:** The screenshot on this page uses the **Elegance Design**, introduced in **2025.3**. If you are using an earlier version, your layout may look different.

## Quick-start

1. Drag **Start SAP Session** onto the canvas.
2. Connect the block in the flow and optionally specify basic parameters such as **Connection** and **Session**.
3. Run the flow when it's ready.

## Building block parameters

Parameters  
* **Block header:** Shows the current name of the **Start SAP Session** block. You can rename it at any time by double-clicking the header and typing a new title to keep flows readable and organized.
* **Connection:** The Connection parameter is used to pass the SAP connection details for an existing connection. Typically, this input is linked from a previous block that has already created or provided the SAP connection, so that the new session is opened against the correct SAP system.
* **Session:** The Session parameter represents the SAP session started by this block. It is used to support SAP's multi-session capability and can be passed to subsequent SAP blocks so they operate within this specific session.
* **Error occurred:** The Error occurred output is triggered if the Start SAP Session block encounters an error during execution. You can use this connector to branch the flow to error-handling logic, logging, or cleanup steps when a session cannot be started successfully.
