n OVP application, here a list UIBB is shown. Now we have a button like Show Excel.

Once this button is pressed, the list data should appear in an excel.

The table type and the line type.

List UIBB feeder class implemented interfaces.

Created an attribute.

Create an OVP application and application configuration and OVP component configuration.

Add the list UIBB configuration.

In list UIBB we have the below fields. Click on Toolbar Schema.

here ww have button with text as ‘Show Excel’ and event as ‘EXCEL_DISP’.

put  the below logic in  PROCESS_EVENT method under the event ‘EXCEL_DISP’.
