Everything in the atlas

Where the release and programming model offer durable locks, as RAP draft handling does, the README states that those solve the problem at the kernel level and the lock manager is for where that is not an option. A running handler occupies one background work process for as long as any lock is held, and only generated `ENQUEUE_*` modules can be locked.

Not on the [SAP BTP ABAP environment](artifact:btp-abap-environment) or another cloud ABAP system: the maintainer states the tool is not cloud ready, because the data sources and system tables it reads CDS metadata from are not released for cloud development. It is designed for SAP S/4HANA on-premise or private cloud, and the shipped Fiori application is configured for A4H and developer systems.

Neither the package manifest nor the repository tree declares a licence.

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 SAP's own Google Workspace integration already applies: the README opens by announcing a native integration between Google Workspace and [SAP S/4HANA](external:sap-s4hana), whose first set of features is included in SAP S/4HANA Cloud 2208 and SAP S/4HANA 2022 and needs an additional licence for the SAP Document Management Service. Not where end users cannot each hold a regular Google account, since there is no way to use an enterprise account or to log on to Google Drive through single sign-on, and not where the redirect URL Google calls cannot reach a public top-level domain server. No SAP standard support is provided for it.

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`.

Not for a table whose contents matter, and not for one chosen at run time: the name of the table is fixed in the calling code, and the maintainer's own warning is "only hardcode the table name, don't use with important tables, use at own risk!"

The app writes to whatever table is passed in the URL parameter `table` and carries no authorisation check of its own, so past a development system it needs authorisation checks added and a restriction on who may run it.

Neither the package manifest nor the repository tree declares a licence.

Not where the system must not trust whatever the source trusts: the README states that you must trust the source, currently Mozilla, because the system can then reach every website holding a certificate generated by a root CA that source supplies. It installs those root CAs automatically, and the maintainer marks the tool use at own risk.

Not for anything important, which is the maintainer's own instruction: the README's Warning section calls it stupid to write your own encryption or PGP library, says abapPGP will most certainly contain severe bugs, and points instead at established PGP software such as [OpenPGP](http://openpgp.org/). Signing is the only scope it states.
