# Troubleshoot Workbench

Access logs and job instances to identify and resolve issues in Workbench.

## About Troubleshooting Workbench {#about}

You can identify issues that occur during Workbench processes using the following methods:
* [_Workbench Logs_][1]
* [Job instances][2]

## Optional: Prerequisites {#prerequisites}

Depending on your business needs, you can configure <a href="/en/lr/542174/">tab collections</a> and the <a href="/en/lr/26387/">object layout</a> for _Workbench Logs_.

## Review Workbench Logs {#workbench-logs}

When an action fails due to a SQL error, you can access _Workbench Logs_ to identify and resolve the SQL issue. To do this:
1. Navigate to **Business Admin > Objects > Workbench Logs**.
2. Select the **Workbench Log**. By default, Vault sorts these logs by the day and time the error was encountered, starting with the most recent.
3. In the _Workbench Log Data_ field, select the attachment to download the error log.

Scenarios where Vault may create a _Workbench Log_ include:
* <a href="/en/lr/752975/">Running a _Workbench Report_</a>
* <a href="/en/lr/860557/#run-all-reports">Running a _Workbench Report Set_</a>
* <a href="/en/lr/860557/#schedule-workbench-report-sets">When scheduled _Workbench Report Sets_ run</a>
* <a href="/en/lr/860557/#generate-reports-safetydocs-pva-scheduling">When scheduled _PVA Obligations_ run</a>
* <a href="/en/lr/831712/#add-filters">Applying filters to a _Workbench Dashboard_</a>

## Review Job Instances {#job-instances}

For certain Workbench jobs, you can <a href="/en/lr/24762/#actions-on-job-instances">download the job instance log</a> to resolve encountered errors. The following table describes the jobs in Workbench for which you can download a log:
