Start SAP Session‎ | Leapwork Docs

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:

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.
