Hi everyone 🙂  
First post here after working for over year with elastic.

I have an index with docs representing items moving from station to station, each doc represents a station.

For example - an item moved between two station will have two docs (random id's):

```auto
{
          "sn": "N00000000000",
          "process_id": "0001",
          "process_name": "distance",
          "station_name": "LAPTOP-999",
          "user": "doron",
          "logged": "2023-09-19T14:09:49.342013+03:00"
}
{
          "sn": "N00000000000",
          "process_id": "0002",
          "process_name": "flow",
          "station_name": "LAPTOP-999",
          "user": "doron",
          "logged": "2023-09-20T11:04:12.342013+03:00"
}

```

I am trying to do a simple metric box in the kibana dashboard to show how many items are in each station, but I want to exclude the ones that already moved to the next station.

That means I'm trying to use count for a sub data only contains the latest occurrence of each **"sn"**

In our example case, The count boxes will be:  
**Distance:** 0  
**Flow:** 1

Please let me know if you further questions!  
I have been stuck on this for a while and really like to understand how to do such a thing generally

_Thanks alot!,_  
_Doron_

Hi, you can utilize the transform feature to get to your desired result.

If you created a [latest transform](https://www.elastic.co/guide/en/elasticsearch/reference/current/transform-overview.html#latest-transform-overview) on your data with a `group_by` on the item id the result will be an index with a single document per item.

This index can then be used as your source data to create the visualizations you need.
