LinkToAction (SAP Library - Keyboard Access for Web Dynpro for ABAP / for Java)

LinkToAction

The LinkToAction UI element is a hypertext link. The navigation to this link triggers a Web Dynpro action.

Note

To enable the development of Structure link accessible applications, the tooltip property is checked during the syntax check if the property text is not set.

A tooltip does not necessarily have to be set for this UI element, but it could make sense to set it if it contains detailed semantic information.
