What do i need for setting up a connection to a local database in Eclipse to start developing in ABAP? I already installed the plugin for ABAP but i can't connect to a database. Any suggestions?
回答1:
ABAP Development Tools (ADT) is an add-on to Eclipse to develop in ABAP, but it's only the frontend software, it requires another software, the "backend" (also called the ABAP-based system).
Did someone give you the credentials to an existing ABAP-based system, or did you install your own free trial system (SAP NetWeaver AS ABAP Developer Edition) or did you subscribe to a cloud-based ABAP non-free trial system?
If you have none of these three systems, then I recommend that you install the free version on your laptop, for instance the latest 7.52 SP04 version.

Unlike other development scenarios, ABAP development requires a backend repository.
Without an SAP Netweaver Stack (ABAP server) there is no repository.
The ABAP repository is where:
- ABAP code is stored,
- ABAP code is compiled
- and where code is executed.
Eclipse is the only the IDE and it is constantly communicating with the ABAP server.

ADT works through RFC connection and requires some ICF services to be enabled on backend. Did you make some necessary configurations in backend? alike:
- profile paramethers
- S_ADT_RES, S_RFC authorizations
