ABAP Service Instance URL Connection

The concept name was not provided, and the supplied sources describe two related but distinct topics — connecting to an ABAP system via an ABAP Cloud project and the ABAP Service Instance URL — without clearly defining a single named concept. Based on the available sources, the ABAP Service Instance URL is the endpoint URL associated with an ABAP service instance on SAP BTP, which a developer uses when creating a new ABAP Cloud project in ABAP development tools to connect to the target ABAP system. It serves as the identifier that links the local development environment to the correct cloud-based ABAP runtime.
