# Viewing Accumulator Data

The **Data** tab displays a history of the changes in value of the source, count and increment tags. Rows where the source tag was reset are highlighted in red.

> ℹ️ **Note**
> ℹ️ 
> ℹ️ You can sort the data table by any of the columns. For example, sort by the *Delta* column to find unusually large increments that may indicate invalid data.

# Deleting Accumulator Data

> ℹ️ **Note**
> ℹ️ 
> ℹ️ You cannot undo this process. If you aren't sure that you want to discard the usage data, use the DMS [Meter Reading Entry module](https://rubiconwater.atlassian.net/wiki/spaces/MNC/pages/2010710149) to adjust the usages instead.

You can use this tool to remove usage data. When you delete a data row, the *Delta* or increment is removed and the subsequent *Accumulator* or count values are recalculated so that these two host tags remain in sync with each other.

> ℹ️ **Caution**
> ℹ️ 
> ℹ️ it is safer to adjust the usage in the DMS Meter Reading Entry module. See the **DMS Meter Reading Entry** module documentation for more details of that process.

1. In the Accumulator module, select the accumulator that you want to modify.
2. On the Data tab, select the row that you want to remove and click **Delete**.

The values in the source column are not affected.
