# Update the Data

After you upload data into a dataset, update it by adding, upserting, or removing data.

To update data, set the Action field to `Process` and the Operation field to `Append`, `Upsert`, or `Delete`.

This example sets the Action and Operation fields to append data to the InsightsExternalData object. To enable faster uploads, use the Mode field with a value of Incremental.

```nolang
SObject sobj = new SObject();
sobj.setType("InsightsExternalData");
sobj.setField("InsightsExternalDataId", parentID);
sobj.setField("Action","Process");
sobj.setField("Operation","Append");
sobj.setField("Mode","Incremental");

SaveResult[] results = partnerConnection.update(new SObject[] { sobj });

for(SaveResult sv:results)
  if(sv.isSuccess())
    parentID = sv.getId();
```

If Mode isn’t specified or is set to `None`, the append is a bulk upload that processes data slower.
