Hi Friends,

Dialog                         dialog;
DialogField                fldDivision
FormStringControl   formStringCtrlDiv;
;

dialog = super();
dialog.addField(typeId(CNLIN_Division)) //Your EDT/field name
formStringCtrlDiv = fldDivision.fieldControl();
formStringCtrlDiv.replaceOnLookup(false);
return dialog;

}
