If you are using messageLovInput you can try this approach.
1. In your CO catch 'lovPrepare' event [this event is triggered when user clicks on the magnifying icon besids the lov]
2. Extract the values based on which you want to filter the LOV data
3. Call VO's initQuery method to modify the Where clause of VO related to this LOV.
Code...
String eventActionParameter = pageContext.getParameter(EVENT_PARAM);
if(eventActionParameter.equals("lovPrepare")) {
//Extract the values
//Call a AM method to very the Where clause
}
