Everything in ABAP

The page and the [abap2UI5](artifact:abap2ui5-abap2ui5) service have to share an origin: an `endpoint` that resolves to another origin is refused, and abap2UI5 rejects a POST whose `Origin` names another host. A host that routes by the URL hash, such as a Fiori elements app or an app with a UI5 router, needs abap2UI5 1.146.0 or later, because 1.145.0 clears the host's hash after every roundtrip. One frontend per page: the first control that starts decides which endpoint the frontend comes from.

Event roundtrips and visual fidelity stay with a live run: the documentation leaves those to the project's MCP server and to [abap2UI5 for VS Code](artifact:abap2ui5-vscode-extension). A class that builds view parts in helper methods without the handle idiom cannot be statically reconstructed, and the render gate is then skipped with a notice while the property gate runs on what was reconstructed. A screenshot is not a preview of the app: nothing round-trips, no event reaches ABAP, and a table filled by a SELECT photographs empty unless a mock JSON file sits beside the source.

Every gate here runs off-system, so what the class does on a real system and what the view does on the oldest UI5 release it has to serve are what the `pitfalls` catalogues carry and no local run can see. It runs abap2UI5 app classes, so ABAP that is not one has nothing here to deploy into. In system mode the sandbox tools are not offered, and an `app_act` event runs on the system as the configured user.

What adt-ls cannot do headless the maintainer puts out of scope, so a consumer that needs an ADT call the language server does not expose is back to speaking ADT itself. The README states the current runtime compatibility as verified on macOS arm64, against adt-ls 1.1.2 as the minimum and `1.1.2.202608131517` as the version tested. An Eclipse installation does not supply that runtime: SAP versions the two separately, so the VS Code extension has to be installed even where nobody opens VS Code.

A descendant rather than a distinct idea: if what you need is the ADT surface itself, its ancestors are entered here too and one of them may already be in your stack.

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.

Quiet No published releases; repository quiet for 41 months.

Functional boundary Not in a production environment yet: the maintainer puts abaK in beta, says its API can still change and more tests are needed, and asks that a non-beta release be waited for.

Written for Amazon Q Developer and Kiro, and the central deployment path is ECS Fargate — the further you are from AWS, the more of it is scaffolding you do not need. Python rather than the Node most of this group uses. Its README says the repository is no longer maintained and that the latest version of ABAP Accelerator is shared after registering with AWS for [Modernization Agents for SAP on AWS](https://github.com/aws-for-sap/Modernization-Agents-for-SAP-on-AWS).

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.

On a system below ABAP 7.51, or one without a connected HANA database, the client-based mode does not run, and the server-based mode is only available where the abap-code-search-tools backend is installed in the system.

On a system where the abap-search-tools backend is not installed: the plugin lists it as a precondition, and the beta update site expects that backend's dev branch in particular.

In beta by its own page's account, where conversion bugs may occur and not all functions and variants are supported yet. The shapes named as not yet supported are sub selects, FOR ALL ENTRIES, functions such as count and sum, and the IN operator with a value list, so a statement built on one of those is outside what the converter sets out to do.

Quiet No published releases; repository quiet for 27 months.

Functional boundary It binds to the .abap and .ABAP file extensions inside Visual Studio Code, so it does nothing for ABAP opened in another editor, or for source read from a system over ADT instead of from a file on disk.

Not a tool a developer runs: it is a library to build one with, and it ships no editor, command line or interface of its own. Its sample connects with a plain HTTP URL, a user and a password, so a system that does not expose the adt ICF service that way is out of reach.

A Python 3.10+ CLI, installed with pipx rather than through any SAP-provided package manager. Its own README lists what it does not do yet: where-used, syntax check and unit test runs — for those it says to reach for [ADT/Eclipse](external:eclipse) or an MCP server. First release, v0.1.0, and no standalone LICENSE file in the repository — the MIT grant is in the README and in pyproject.toml's project metadata rather than its own file.

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.

Server side only, and deliberately: the author states there is no realistic way to support the SSE streaming a client needs, so there are no notifications, no `listChanged`, no `subscribe` and no logging. It is also frozen — protocol versions up to 2025-11-25 and no further, with everything after that in a separate V2 SDK, so starting here today is starting on a closed branch.

Stateless by design: with no `Mcp-Session-Id` and no SSE, notifications of any kind, `resources/subscribe` and stream-close cancellation are excluded, which the author states are protocol-level impossibilities on stateless ICF rather than gaps to be filled later within this design. ABAP Cloud is not supported and not planned, the stated reason being SAP pushing its own MCP strategy and features in BTP; the first iteration targets 7.5x classic, with 7.02 to 7.4x served from a separate generated downport repository. No authorization object and no default auth check are delivered, so a user who may call the ICF node may call every `AREA`/`SERVER` registered under it until `check_authorization` is redefined.

Not a way to run existing reports unchanged: a report is rewritten as a class, and `CALL SCREEN`, dynpro modules, batch input, `SUBMIT` and native SQL are refused by the converter rather than mapped. Not an SAP GUI in the browser either: the programming model is classic and the screens are UI5, and the README points at abap2UI5-addons/sapgui for SE16N or SM37. Output has gaps the README names — ALV cells show dates and times as the model carries them rather than in the user's format, print is a text file because ABAP Cloud has no spool, and value tables for F4 are read on premise only.

A system below ABAP 7.50: some of the classes it uses are only available from 7.50, and the maintainer states that downward compatibility to 7.40 in a single branch is currently not possible without resorting to dynamic programming.

Not a substitute for testing in a system: the README states that any class calling the database, classic BAPIs or HTTP is shimmed out and stays an on-stack ATC and ABAP Unit concern, and that an off-stack green is CI-grade provenance rather than an in-system pass. It also assumes a particular shape of project. The ABAP has to be abapGit-serialised into a Git repository, Node.js 22 or later has to be available locally and in CI, and the CI has to be GitHub Actions.

Anything below SAP S/4HANA 2023 FPS03 (ABAP 7.58), and any system not running the ABAP Cloud development model: those two are the prerequisites the README names, and it states that the framework targets ABAP Cloud exclusively.

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.

Not below SAP_BASIS 7.40 SP08, and not on [SAP S/4HANA Cloud Public Edition](external:sap-s4hana-cloud-public-edition) or [the SAP BTP ABAP environment](artifact:btp-abap-environment), where the classic transport check, the report and job calls and the cluster table `INDX` it rests on do not exist and the maintainer names gCTS as the answer instead. Only on a development system where every developer is trusted: each developer's GitHub token is kept in a cluster table encrypted with a key held in the same table, so anybody who can run ABAP on that system can read both, and the separation between author and reviewer holds only as far as that trust does. Not where the gate has to be unconditional — `#NOREVIEW` in a request's short text skips the check for that request, `ZTR_DISABLED` switches it off for a system, a check that cannot reach GitHub lets the release go on, and nothing checks who writes the marker.

The embedded preview needs a system that accepts basic auth: the documentation states that pure SSO or SAML without a basic-auth fallback is not supported, and points at `external` mode, which opens the app in the normal browser with the existing SAP session. On the web only the language half runs; the preview with its proxy, traffic log and screenshot, Ctrl+F3 activation, the render gate, the workspace-wide check and the MCP servers are desktop-only. The agent app tools send nothing until `abap2ui5.agent.enableAppTools` is switched on in User settings, because an event they fire runs as the configured user and changes data on the system for real.

The frontend is optional: where abap2UI5 apps are reached through the framework's own HTTP service, nothing from here is installed. In S/4 Public Cloud that endpoint needs `S_DEVELOP` authorisation, which the installation guide states makes it unfit for production, and the separate frontend app with an extra tile is what it names for business users. The `cloud_new` and `standard_new` branches need an abap2UI5 newer than 1.146.0 on the system.

Not for views built from controls outside the portable profile: sap.ui.table, sap.f, sap.uxap, sap.ui.comp and z2ui5.cc custom controls render as a visible unsupported-control box and are listed in the diagnostics, and `CONTROL_BY_ID` and `BINDING_CALL` stay unsupported. Nine frontend actions the profile allows, `DOWNLOAD_B64_FILE` and `SYSTEM_LOGOUT` among them, are skipped and reported rather than run, and formatters other than the profile's `Formatter.Date*` render a placeholder.

There is no control tree: visibility and enablement are not evaluated, and `set_value( )` is not checked against the bound paths. The frontend `CONFIG` (device, UI5 version, focus, scroll) is not sent at all, so an app that branches on device or theme sees initial values. It drives `z2ui5_cl_ui5_handler` and the draft service, which the README states are not part of abap2UI5's released API in `src/02`, so a core change there can require a change here.

The class has to be moved by hand: an abapGit pull of the exported ZIP, or a paste into ADT or SE24. The palette is held to the 121 controls of UI5 1.71, and a control inserted by its class name instead comes from whatever UI5 the canvas has loaded, with nothing checking it against 1.71 - *Checks* reports that. An app class that builds no view, or more than one, is refused.

A `SELECT` from a business table has nothing to select from: the database in the page holds the framework's own tables, and nothing can reach outside the browser, so an app that reads a system's data cannot be tried here. Only the UI5 libraries built in are available and a control from anywhere else will not load; what the transpiler cannot compile is reported in the output panel rather than run. State lives in the tab — a reload, and a press of Run, starts over on a fresh database.

Neither suite has been run against an ABAP system: the reference backends are the framework transpiled to Node and cap2UI5 on CAP, so what a check does on a real system is open. The portable profile is a subset of 61 controls, filled from a census of 247 core apps of which 64.8 % run unchanged, so an app outside it renders placeholders in the terminal and Adaptive Cards renderers.

A sample that needs something the system provides is not here — the samples-stack repository holds the OData, RAP, WebSocket and launchpad demos, and samples-controls the rebuilds of the UI5 Demo Kit originals. Every class in `src/` keeps to controls and properties available since UI5 1.71 and not deprecated, apart from two clipboard samples marked `(UI5 1.119+)`, so a newer control is not demonstrated here. Numbers are handed out per repository and reused across the three, so `493` alone does not name a sample: `Z2UI5_CL_SMP_APP_493` is the Hello World here.

Not on ABAP Cloud: most of the libraries use APIs that are not released there, and the repository has no ABAP Cloud gate yet. Not beyond a development system without authorisation checks added first — the samples carry none of their own, the abap-fm-logger sample reads the log table `ZAFL_LOG` with whatever the logged calls received and returned, and the abap_fm_json sample calls function modules, limited to a hard-coded whitelist.

The value-help and search-help popups read whichever DDIC check table the user selects without an authorisation check of their own, so the README asks for your own checks and a restriction on which tables may be browsed before they are used beyond a development system. The transport-request popup works only on-premise, and the search help does not yet run on the Cloud stack.

Not an end-user app: it reads from any table the user names and writes into tables of the Z/Y namespace, with no authorisation check of its own, so the README asks a project to add its own checks on `S_TABU_DIS`/`S_TABU_NAM` and to restrict who may run it before it is used beyond a development system. XLSX upload and download are not ready for ABAP Cloud yet, and of the upload apps only the JSON one writes the file's rows back to the database.

Not where the framework code itself has to change: `input/` and the three installable branches are overwritten by the workflows on every upstream push, and a framework change is a pull request to abap2UI5. Bug reports and feature requests also go to the abap2UI5 repository rather than this one.

The 221 ports under `src/02` need a UI5 runtime newer than 1.71: they install and activate on any release, and on an older UI5 the newer control does not render. The `src/03` collection is hand-written for SAPUI5-only controls and needs a SAPUI5 bootstrap. There are no per-library branches, so pulling the whole repository is the one way in and the activation takes a few minutes.

Not the place to learn abap2UI5 itself: every package starts from a technology the system already provides, and the framework basics and the control gallery are the other two sample repositories, abap2UI5/samples and abap2UI5/samples-controls. Three packages are out of reach on ABAP Cloud, and `05` needs the 2021 release that carries RAP business events.
