## Summary

The **pre-analysis completeness check** can help you assess the completeness of a general ledger (GL) by comparing top-level closing balances with calculated values. This check, performed before an analysis is run, enables you to identify and correct any data or [account mapping](https://support.mindbridge.ai/hc/en-us/articles/9553833993495) issues before running the analysis.

## Access the _Completeness check_

You can access the pre-analysis completeness check from the [_Data_ page](https://support.mindbridge.ai/hc/en-us/articles/4411133015703-Pre-analysis-completeness-check-General-ledger#h_01HBS4WG3THKEB8JBAMBP1D1MS), or from the [_Verify accounts_ workflow](https://support.mindbridge.ai/hc/en-us/articles/4411133015703-Pre-analysis-completeness-check-General-ledger#h_01HBS4WG3T55M7CH7J6BP226Z6), provided that an opening balance file, a closing balance file, and a general ledger file have been imported into a _General ledger analysis_ on the _Data_ page.

### From the _Data_ page

1. Open the **more actions menu** (  ) in line with the analysis name.
2. Select **View checklist**. The import checklist appears.
3. Use the **chevron** icon (  ) beside the _Reports dashboard_ header to expand the section.
4. Find the _Pre-analysis completeness check_ and select **Calculate balances** (or **Recalculate balances** if you have already verified the accounts).
5. Compare the top-level balances to the calculated values, or **Export** the report for a complete account list. If you export, the Excel file will appear in your default download location.

### From the _Verify accounts_ workflow

On the _Review_ step, you can run a completeness check on the analysis of your choice.

1. Use the **View** menu (located on the left side of the page) to select the analysis you want to run a completeness check on.
2. Select **Export completeness check** (located on the right side of the page). The Excel file will appear in your default download location.

**Note:** If a file is replaced or an account mapping is changed, select **Recalculate balances** to see the most up-to-date information.

**Note:** Once the analysis has been run, you can view and export the finalized [Completeness Check Report](https://support.mindbridge.ai/hc/en-us/articles/1500006915781) from the _[Reports](https://support.mindbridge.ai/hc/en-us/articles/360058192613-How-to-generate-reports)_ tab.

## How completeness is calculated

It is important to understand the math behind the scenes of the pre-analysis completeness check.

**_Opening balance + GL activity = Closing balance_**

If you have provided the files for the 3 components in the above equation, MindBridge will start by calculating the left side of the equation (opening balance + GL activity). This calculation is performed for each account and is then compared against the accounts in the supplied closing balance file.

There are 3 possible outcomes for each account using this calculated approach:

1. **Balanced:** If the number that MindBridge calculated is the same as the number in the supplied closing balance file, it will be considered balanced.
2. **Within tolerance:** If the number that MindBridge calculated is within the designated tolerance amount (the $1.00 default is only adjustable on the Reports tab after running the analysis) from the number in the supplied closing balance file, it will be considered within tolerance.
3. **Out of balance:** If the number that MindBridge calculated is outside the designated tolerance amount compared to the number in the supplied closing balance file, it will be considered out of balance.
