試試這樣說：

var update = db.collection.update(
            { _id:ObjectId("id_of_record")}, 
            { $set: { "Details.$.Items.$.Description":"Discriptionqwe" } } 
          ); 

    var is_row_affected = db.runCommand({getLastError : 1});         

    if(is_row_affected['updatedExisting'] == true){ 
     result = {msg: '1', data: []}; 
    }else { 
     result = { msg: '0', data: []}; 
    } 
    return result;
