ETL Virtual Applet

A registry row with no screen behind it, so that a service account which reads and writes through the API can be linked to an applet, placed in a catalogue and given an installation with a rank, like a human user. Nobody opens it, and despite its registry description no code extracts, transforms or loads anything; installed on a person’s login it appears in the launchpad and opens nothing.

Overview

The ETL Virtual Applet is an applet-registry row with no user interface. Its bundle address is a placeholder, its applet type is ETL-CLIENT, and no screen is built for it. Nobody opens it. It exists so that an ETL (extract, transform, load) client login — a service account that reads and writes through the API — can be linked to an applet in the same tables as a human user, and therefore be placed in a catalogue and given an installation with a rank.

The registry description promises that “the Virtual ETL applet enables users to extract, transform and load data across systems”. No code does that; the row is a label.

Where it fits

Direction	What	Why
Sibling	Platform SysAdmin	Where the row is put into catalogues and installed for logins.
Sibling	Developer SysAdmin Applet	Where the row itself is maintained.

Screens and menus

None. A front-end project exists under the applet’s name, but it is an unfinished template with no screen of its own, and it is not what the registry serves.

Configuration

No exposed control found — there is nothing to render. The backend’s only relationship with the row is generic: when it checks whether a login may use or edit an applet, it looks up the login’s applet links, and this row can be that applet like any other. ETL-CLIENT is simply one of the allowed applet types.

Fields

None.

Lifecycle and effects

Installing this applet for a login links the login to the applet (Platform SysAdmin → Catalogue → Applet → Install For User); nothing else happens. No document, journal or stock effect.

Related applets

Platform SysAdmin — catalogues and installs it.
Developer SysAdmin Applet — maintains the row.

Troubleshooting

The applet appears in a user’s launchpad and opens nothing	There is no screen behind the registry row.	Expected. Uninstall it from human logins; keep it on service-account logins that need an applet link.
