UI written in ABAP

Stateful apps do not work through it: an app calling `client->set_session_stateful( )` needs the ICF session of the system it runs on, and the consumer opens a new HTTP connection per request without forwarding the `sap-contextid` header that addresses that session. Request headers do not cross either, and a user exit on the source system sees the path of the node `/sap/bc/z2ui5_http_srv` rather than the consumer's. For ABAP Cloud there is only the `cloud` branch, which the README describes as an unmaintained prototype from 2025-11, consumer side only and with no CI.

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.

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 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.

Needs Standard ABAP 7.50 or higher, and an abap2UI5 whose frontend reserves the resourceRoot `z2ui5_cci`: a frontend predating that rename reserves `z2ui5ccc` and cannot resolve the controls. Frontend artefacts only one company needs, such as an in-house reuse library, a corporate icon font or company CSS, are what [abap2UI5-addons/custom-controls-customer](https://github.com/abap2UI5-addons/custom-controls-customer) is for, the same mechanism under the second reserved root `z2ui5_ccc`. ExportSpreadsheet needs SAPUI5: under OpenUI5 `sap.ui.export` is missing and the button renders disabled.

The layout is rendered into an [abap2UI5](artifact:abap2ui5-abap2ui5) view and its events are passed on from the app's `main` method, so there is nothing here for a UI outside an abap2UI5 app. Shared layouts stay denied until a class implementing `z2ui5_if_layo_auth` exists in the system, so an installation whose key users are to maintain shared layouts has that class and its authorization object to write first.

Not the whole addon in ABAP Cloud: the DDIC annotation service is not released there, so the annotations come through XCO instead, a database table is read-only, the DDL source is not read, and the cloud path was written without a cloud system to run it on. Not for a plain internal table, since it renders from CDS annotations; the README points at `z2ui5_cl_ui5_view_builder` for that case. As of 2026-10 the maintainer states that none of it has been clicked through in an SAP system: the RAP write path and the reading of metadata extensions were written from documentation and pass the three offline gates only.

The `PARAMETERS`-style selection screen with event blocks is not here: `z2ui5_cl_sel_screen` and `z2ui5_cl_sel_screen_sel` are a skeleton whose methods are still empty, and the README points at [abap-cloud-gui](artifact:abap2ui5-addons-abap-cloud-gui) for a full report-style screen.

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.
