# Review and mine

# Review and mine your project {#ariaid-title1}

Release version: Australia  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 2 minutes to read  
After you've created the project by setting the objectives, scoping the analysis, and adding improvement opportunities, it's time to mine the project.

## Before you begin

Role required: sn_process_mining_analyst, sn_process_mining_power_user, or sn_process_mining_admin

## About this task

Record limits for Process Mining projects

Process Mining enforces a maximum of 500,000 records from the primary table. This limit scales down proportionally as child tables are added to the project.
{#review-mine__entry__2}

| Table configuration | Record limit |
|-|-|
| 1 table | 500,000 |
| 1 table + 1 child | \~250,000 |
| 1 table + 2 children | \~125,000 |
| 1 table + 3 children | \~100,000 |
[Table 1. Flat table structures]

Nested child tables reduce the record limit significantly more than flat structures, because deeper relationships multiply the processing cost per record.
{#review-mine__entry__12}

| Table configuration | Record limit |
|-|-|
| 1 table → child → grandchild → great-grandchild | \~71,000 |
[Table 2. Nested (chained) table structures]

What happens when the limit is exceeded

If your record count exceeds the adjusted limit, mining is blocked. To resolve this:

* Narrow your project filter to reduce the number of records.
* Simplify your table structure by removing unnecessary child or nested tables.

## Procedure

1. Navigate to WorkspacesProcess Mining Workspace.  
   If you continue from the Improvement opportunities page, you are on the Review and mine page.
2. Select Edit for the project that you want to review and mine.  
   You're taken to the Review and mine tab.
3. On the Review and mine tab, review the project.  
   You can do some additional steps on this page.

   * Select Manage watchlist to add users who receive notifications regarding the status of the mined project.
   * Select Copy project definition to copy the project.

     When you copy a project, the associated improvement opportunities also get copied.
   * Select Extract data logs to view any logs available.
   * Select Delete to delete the project.
   {#review-mine__ul_onm_vjr_d1c}
4. Select Mine Project to mine the project.
5. On the Mine window, select Sample Mine or Full Mine, and select Confirm \& Mine.

## Result

The Mining Progress page is displayed. After the mining is completed, a Mining Summary page is displayed. This page provides additional details about the mining. It also lists any
finding definition that wasn't included in the mining and provides a link to understand the actual cause. You can also view the logs or go to the Process Mining Workspace and view the graph.  
Note:  
If you select Full Mine and your project includes consumption-based tables, a warning message appears when the number of records exceeds the threshold defined in the `promin.metered_usage.warning_limit` property. To turn off this warning, set the `promin.metered_usage.warning_limit` property to **-1**. The default value for this property is -1, which means it is turned off.
