Using Parameters in a Form
You want to merge data into a form that has not been determined when you create the form. This data could be:
Data selected from database tables of your application. You pass them in the form interface.
Data provided by the SAP Standard or by Smart Forms. This could be, for example, the date or the current page number.
Data you calculated or introduced yourself in the form, for example to display totals in a table.
All this data is determined only at runtime of the form and then included into it. You use
fields
as placeholders in the form to determine how and where to display this data. To include these fields, you use text nodes. At runtime the system replaces them with the corresponding values.
Features
Smart Forms provide the following possibilities to merge data into the form:
A form interface in which you define parameters for application data (see Passing Data to the Form). You can use these parameters as fields for displaying table data.
Global definitions that you use to define your own fields (for example, work areas to display internal tables).
System fields whose contents are predetermined (date, page number).
