The Entities & Fields tab shows which tables and which columns are producing your audit volume. It is the tab to use when you want to reduce noise or explain why storage is growing.

Select Dashboard in the left navigation, then Entities & Fields.

Most Active Entities

The top 10 entities by total operations.

Figure 1. The Entities & Fields tab showing Most Active Entities and Avg Fields Changed per Record.

In most environments one or two entities dominate. That is normal. What matters is whether the entities at the top are ones you would expect.

Avg Fields Changed per Record

The average number of fields that change each time a record in that entity is updated, for the top 10 entities.

Higher means noisier. An entity where five fields change on every single update generates far more audit detail than one where a single field changes.

This is the chart that explains volume that Most Active Entities alone cannot. An entity can sit mid table for operation count and still be a major contributor to storage because every one of its updates is heavy.

Most Modified Fields

The change distribution at column level, over the last 90 days.

Figure 2. The Most Modified Fields card showing attribute level change distribution over the last 90 days.

This is where you find the individual culprit. A single field that changes tens of thousands of times, often a status, a timestamp or a calculated value updated by an automated process, can account for most of an environment's audit volume on its own.

Using this to reduce noise

Read the three charts together:

1. Most Active Entities tells you which table.
2. Avg Fields Changed per Record tells you whether its updates are heavy.
3. Most Modified Fields tells you which column specifically.

Once you have a column that is generating a lot of change and carries little audit value, you can consider turning auditing off for it in Dynamics 365. See Enabling Auditing on a Field for where auditing is controlled.

Be deliberate about this. Auditing you switch off stops being recorded from that moment, and cannot be recovered retrospectively. Reducing noise is worth doing, but not at the cost of an audit trail you later need.

Note

Entity names here are your own Dynamics 365 tables, so this tab looks different in every environment.
