Everything in the atlas

On an [SAP BTP ABAP environment](artifact:btp-abap-environment) system only the generated code is left: DDIC creation is not supported on ABAP Cloud, because classic DDIC object creation over REST is not available there. Create DDIC is also disabled where ADT is not installed in the same Eclipse, and Insert into Editor then works with any editor implementing `ITextEditor` instead of the ABAP one.

In the Eclipse mode the server lives in a developer's IDE, binds to 127.0.0.1 and answers any request carrying an `Origin` header with HTTP 403, so a pipeline or a remote agent has nothing to reach; the standalone mode on the runtime of the ADT for VS Code extension is the documented route with no IDE open. A new connection starts in write mode, so the 11 write tools are live against a connected system until someone presses Toggle Read-Only. The dropins route for the two bundles is documented as untested.

An Eclipse installation older than the 2026-03 release, or a Java below 21, cannot take it: both are listed prerequisites, and 2026-03 is named as the oldest release the current ADT installs on. The tenant, region, client ID and client secret are entered per installation in Eclipse preferences, so each developer configures the Cloud ALM connection in their own IDE.
