1. Choose Administration → Settings.
2. From the Section dropdown box, select Server Settings.
3. Enter the name of the object server.

Make sure that the object server name is unique within your system landscape or even globally. The value of the parameter must be equal to an ABAP namespace (without the enclosing slashes) that is reserved on SAP Service Marketplace at service.sap.com/namespaces. If you do not have an ABAP namespace, enter the name of the host where your SLD is running.
If SLD acts as:
● A landscape directory in your system landscape, the name of the host where your SLD is running is sufficient.
● A name server for the SAP NetWeaver Development Infrastructure, the name must be reserved on SAP Service Marketplace. For more information, see SAP Notes 105132 and 710315.
4. Specify a Working Directory for the application configuration.
5. Specify writing authorization:
a. None – there are no write restrictions (normal mode).
b. Single User – only the current user has write access (exclusive write mode).
c. Read-only – no user have write access (read-only access).
6. Choose Save.
