In User Management Engine (UME) you have assigned your user to the group NWDI.Administrators. This group is created with a CTC template for Development Infrastructure (DI) and is only available on systems that were configured with this template.
If you run CM Services on a system other than SAP NetWeaver Development Infrastructure, then you need the role SAP_DI_ADMINISTRATOR or a group that contains this role.
For more information actions available for Change Management Services which you can use to create your own roles, see Authorizations for Change Management Services .
Use the Configuration Service (also known as Development Configuration Management) when developing with Java and you want to manage it with Transport Management System (TMS).
In addition to this you can use the Configuration Service to set up your local Java development environment without transport routes to other development configurations and without embedding it in a CTS transport landscape (standalone development configuration). For example, you can specify and change the Build Tool Location, Repository Location, or software components that are to be developed for a development configuration.
Ensure that you can include those non-ABAP systems in transport domains in the TMS with this service which use the SAP NetWeaver Development Infrastructure (NWDI) for the management and building of Java sources. You can import development configurations that were edited with this service into the SAP NetWeaver Developer Studio (NWDS).
