Can you check if duplicate data is coming from backend . If yes , you can remove duplicates at back end and send the unique values.

Check if you add sy-langu check at backend where select query is written

Also , there might be case where key is unique but description is same for 2 keys and it appears as duplicate

Hi Ashok,

Before binding the value(setProperty) to the combo box, run the forloop and using indexOf function check whether existing entries are available like below.

for(var i=0; i<country.length; i++) {
 if(a.indexOf(country[i].Country) === -1) {
    a.push(country[i].Country);
  }
}
