Go to cluster-data > template – Usage_Type_All_in_One. Double click on the instance – IDxxxxx.
In the Servers tab you will see the field Custom Number of Server Nodes (or Custom Number of Server Processes in AS Java 7.3 or higher), type in the number of server nodes desired.
Click in the Set button right below.
Click in the Save button (Apply changes) at the top bar. Restart the SAP system.
