# Configuring system under test

> Configuration steps for the System Under Test, including user setup and authorization assignments required for test automation in Automation Suite.

To perform test automation in your System Under Test (SUT), you need to set up the right user and assign the correct authorizations.

To configure your system under test, follow these procedures:

1. [Set Up Communication Users](https://docs.uipath.com/test-manager/automation-suite/2.2510/user-guide/system-under-test-configuration#configuring-system-under-test)
2. [Enable SAP GUI Scripting](https://docs.uipath.com/test-manager/automation-suite/2.2510/user-guide/system-under-test-configuration#configuring-system-under-test)
3. [Enable eCATT](https://docs.uipath.com/test-manager/automation-suite/2.2510/user-guide/system-under-test-configuration#configuring-system-under-test)

## Set up communication users

You need to manually create the user ECATT_ET_USR in the SUT.

1. Create ECATT_ET_USR in transaction **SU01**.
2. Ensure that the user type is **System**.
3. The password for both users (in SAP Solution Manager and SUT) should be the same to ensure seamless integration.

## Enable SAP GUI scripting

Studio and Robots require SAP WinGUI scripting to be enabled on the local machine as well as on the server side. Before you can create your first automation projects for SAP, you need to go over the [configuration steps](https://docs.uipath.com/studio/standalone/2023.10/user-guide/sap-wingui-configuration-steps).

## Enable ECATT

You need to enable eCATT to be executed on each client where testing will be taking place.

1. Start transaction **SCC4**.
2. Select the corresponding clients.
3. Go to **Details**.
4. Under the **CATT and eCATT Restrictions** section, set eCATT and CATT to **Allowed**.
5. Select **Save** to confirm changes.

## Result

The System Under Test is configured with the ECATT_ET_USR communication user, SAP GUI scripting enabled, and eCATT allowed. The system is ready for automated test execution through Test Manager.
