We are developing the HCM forms. Our requirement is populating the Country values in one dropdown list and based on the country we need to populate the city's in other dropdown list. The city values will come from the backed (BADI logic). The event is triggering and the city values also getting but the complete form getting refreshing when ever event is triggering, i don't want to refresh all the form, only related fields need to refresh.
The below events are added to my Country dropdown exit event
$record.CONTROL_PARAM.ISR_EVENT = "USER_EVENT_INITIALIZE"
Please can any one help me on this.
