Next we need to create an SCM instance, which defines the location of the source code repository. SCM instances are not environment specific, so we will only configure this once.
To view the list of instances defined within FlexDeploy, select Topology -> Instances from the menu.
To create the SCM instance, click on Create and select SCM Instance. 
Fill in the information according to the SCM type you will be using to store your Oracle EBS customizations. Click the Test Connection but to validate the configuration. 
Click Save.
