if (deptlistjson){

    JavaType javaType = objectMapper.getTypeFactory().constructParametricType(ArrayList.class, Map.class)
    ArrayList<Map<String,String>> flowlist=objectMapper.readValue(flistjson, javaType) as ArrayList<Map<String,String>>;
    for (def f : flistjson){
        String code=f("C")
        if (code.contains("-")){
            String[] codes=code.split("-")
