Add the component wdr_ovs in your component.
Go to your view, Inside of the view select properties tab and add component usage.pop up will come like this screen shot. Inside of the pop up select interface controller.
After selection of interface controller the screen should be like this.
Go to component controller context and create node and attributes .
When creation of attributes the input help mode should be object value selector
When creation of attributes click f4 help for ovs component usage. One pop up shows the component usage which already you added in component.
Go to context tab in view and map the node from component controller context to view context,
After mapping the screen should be like this.
Go to layout tab in view and create one label for input field .The type should be label and create one input field for this label with type of input field like label.
IN Property of label give text name as Vendor number.
In Properties of label fill the field label for (input field).
In properties of input field bind the value from context node.
Value now binded.
Create one event handler method in view. when you select the ovs from popup some coding automatically generate in inside of method.
Then click on that method coding already there, we have to change some coding depends upon our search help field. Field name and field text for start search.
Modify the program like below .
declare data structures for the fields to be displayed and
* for the table columns of the selection list, if necessary
types:
begin of lty_stru_input,
* add fields for the display of your search input here
lifnr type lifnr,
name1 type name1_gp,
end of lty_stru_input.
