Use
The help for a Web application should not use a standardized F1 help (popup window with a short text and documentation) for all the visualized fields of the application, as is common in R/3. Instead, the individual pages of the application should be designed to be intuitive and easy to understand.
Depending on the application, however, it might be necessary to include some explanations. In this case there should be a precise, application-specific help available. This can be done in two steps.
Examples:
Dictionary fields: SFLIGHT-CONNID and SFLIGHT-CARRID.
Input Field with Quickinfo

Table with Quickinfo as Column Header
