You can add a value help button to your model that the user can click to display a dialog box that lists valid values. This helps the user select the right value to submit in an input form.

Procedure

  1. On the Layout tab, right-click a field in an input form, and from the context menu, choose Add Value Help.

  2. In the Add Value Help for Selected Input Field dialog box, from the Type drop-down list, select the type of value help to create. Notice that information about the selected field appears in the Properties section of the screen. Uncheck the Hide advanced configuration options (BI systems only) checkbox, so that you will be able to see the advanced Specify Data Service Runtime Parameters screen (step 5, below). Click Next.

  3. In the Select Data Service dialog box, identify the data service that will provide the actual values for the value help list (refer to Find Data, which describes the similar Find Data task panel). In typical cases, this will be the data service of the input field itself, but you could use values from any data service.

    Note Note

    You can use a JDBC-based stored procedure as your data service that provides the values for the value help. The procedure is similar to that described in Create a Dynamic Entry List with a JDBC-based Stored Procedure.

    End of the note.

  4. In the Properties section, select whether to retrieve values for the list from the Dimension Table or Master Data Table from the Get data from drop-down list. Click Next.

  5. Configure value help parameters on the Specify Data Service Runtime Parameters screen:

    1. In the Input section, select the port for the input value, pre-configure values for the list if desired, and configure search functionality if desired.

    2. In the Output section, select the port for the output value, configure which type or types of fields to display, and select the key field to deliver to the query.

  6. Click Finish.

Result

A Value Help button is created next to the input field on the form. When the user presses the button, a dialog box appears that lists valid values for the field:
