Input Help
Use
Data input is an important activity in interactive business applications. In a large number of dialog variants valid input represents one value from a limited set of values. Users can select a value from a table containing possible values.
Input Help for Web Dynpro ABAP
Web Dynpro ABAP provides you with different types of input help. Which type of input help you choose depends on the application.
-
The Web Dynpro ABAP framework provides you with the following predefined types of input help:
-
This input help is based on the search help function in the ABAP Dictionary in the SAP system. You use search helps for data elements and structures defined in the ABAP Dictionary, provided these are supported by Web Dynpro.
-
You can use the object value selection input help if it is not possible to use the ABAP Dictionary for the search, for example if the value set is to be calculated in the Web Dynpro application.
If implemented appropriately both these predefined input help types have the advantage that you can fill multiple fields at a time (for example, two fields for the name of a town and its country).
-
-
In addition, you can program your own input help.
-
You can add further restrictions to your input help by using Select Options.
-
Permitted values can also be displayed while the user is entering a value in the input field. For more information, see Suggested Values for Input Fields.
You can combine the available input help with various UI elements (e.g. InputField, DropDownByKey). You can define an input help for an InputField in a context attribute that is bound to the value property of the InputField. Once an input help has been integrated, Web Dynpro Framework automatically generates and implements the correct icon for the user to choose to call the input help at runtime. In the same way, the F4 key is also available for calling input help.
