Everything in ABAP

Only on SAP S/4HANA 2023 and 2025, on premise or private cloud: [SAP S/4HANA Cloud, Public Edition](external:sap-s4hana-cloud-public-edition) and the [SAP BTP ABAP environment](artifact:btp-abap-environment) are listed as coming soon, and a 2023 system has to leave out `ZABAP_PRC_EVENTS_SE_2025`, whose event-based side effects rely on APIs released with S/4HANA 2025. Not for a system that already carries a copy, because object names are global and two versions cannot live side by side, and not for a productive system by way of the `ZABAP_PRC_DEMO*` packages, which the README states are not intended for one and whose init classes delete and rebuild their own tables on every run. While the major version is 0 the public API is not stable: minor bumps carry breaking changes with no deprecation period, so productive use means pinning a tag and reading the CHANGELOG before every upgrade.

The generated files are copied or deployed into the ABAP system by hand, the fourth step of its own usage list, so nothing keeps an activated service in step with the model it was generated from. Its peer dependency is `@sap/cds` ^9.8, so it does not install into a project on an earlier CAP release.

There is nothing here for ABAP for Cloud: the requirements name Standard ABAP releases only, and a CDS/SADL based OData service for `ABAP for Cloud` compatibility stands under Limitations & Todo.

Not a system to run a business application on: there is no business application in it, and what it implements of the language, the dictionary and Gateway is a stated subset of each. It is a clean-room reimplementation of the `/IWBEP/` interfaces that bundles no SAP source and no standard DDIC, so a service that reads standard objects has nothing to read, and `ANORMALIES.md` records every place the runtime differs from SAP before any workaround is written.

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.

The project states that until v1.0.0 is reached, breaking changes may occur without prior notice. Rule items do not chain: every rule operates on the original input string, so a format whose second step needs the result of the first needs a custom logic class. A REPLACE rule whose replacement produces the exact same string as the input is reported as `no match`, which the documentation records as a known limitation.

Stateful apps cannot be operated: a stateful session lives in one HTTP request and an MCP call is one request, so `app_start` refuses them. The repository carries no release yet and states the addon has not been run in production use, the 7.02 downport is lint-only with no 7.02 system having run it, and the ABAP Cloud HTTP service setup is written down but still to verify on your own system.

Input arrives only as JSON, or as plain XML if the ABAP built-in transformation is switched on, whatever the output format is set to. Cross-site calls are limited to JSONP: the maintainer lists CORS support as planned.

DataZoo GmbH calls the extension experimental and states that minimal testing and benchmarking were done. The Business Source License 1.1 it carries restricts offering the software to third parties on a hosted or embedded basis, so an embedding product needs a commercial licence. Telemetry is on by default and is switched off per session with `SET erpl_telemetry_enabled = false` or for the machine with `DATAZOO_DISABLE_TELEMETRY=1`.

BUSL-1.1 rather than node-rfc's Apache-2.0, so a product you distribute has to be read against the licence and its Additional Use Grant first, and the source is closed: the GitHub repository is the issue tracker and the documentation, nothing else. `RfcServerOptions.bgRfcHandlers` raises instead of accepting handlers, so a server receiving inbound bgRFC units is outside what this does. An ABAP `MESSAGE`-raised failure still arrives with its T100 template rather than the rendered sentence, and the dump name is not reported as `key` for that case.

For an app that calls `client->set_session_stateful( )`, which needs the ICF session of the system it runs on; apps keeping their state in the draft table, the abap2UI5 default, work unchanged. For an app that reads a request header through the user exit on the source system, because the consumer forwards method, body, path, query string and status, not headers.
