Implementing Input Help

Use

To implement field-specific input help, you need to find values that match certain selection criteria specified by the user.

The input help supported by the Internet Transaction Server (ITS) in Web transactions is similar to the input help in SAP system, because it is an HTML version of the input help available in SAP system. In both SAP system and HTML, the availability of input help for a particular field is evident from the presence of a pushbutton on the right of the field.

To implement input help for a field in a Web transaction, you must modify the HTML template to display a possible entries pushbutton next to that field. To do this, you can use the macro searchhelp.
