# How to fix attribution setting discrepancies in Facebook Ads data

Facebook made a [broad set of changes to attribution settings](https://www.facebook.com/business/help/395050428485124?id=428636648170202) following Apple's[iOS 14 update](/v1/docs/facebook-ads-and-ios-14-what-you-need-to-know) in early 2021. Some of the changes have the potential to cause discrepancies when reporting Facebook Ads data in Supermetrics.

These errors occur at the query level in Supermetrics. Every affected query should be individually updated. Use the instructions below to find the specific steps for your impacted query.

To change the conversion attribution setting in our data destinations:

- In Google Sheets, Excel, Power BI, and Query Manager: Select a Facebook Ads query to modify and go to **Options** in the sidebar.
- In Data Studio: Go to the **Edit connection** view.
- For data warehouse transfers: Go to **General settings** in the transfer configuration view.

****Queries using attribution setting****

If your Supermetrics query has a conversion window that doesn't match the attribution setting you see in Facebook Ad Manager, your conversion results won't align.

**Solution 1: Check that your attribution settings align**

If the attribution setting in your query doesn't match the one you see in Facebook Ad Manager, a discrepancy can result.

**To fix this:**

- Check which attribution setting you're using in the impacted query and in Facebook Ads Manager. If they're different, adjust them so that they match.
- If your Ad sets/Campaigns have multiple attribution settings, reset your attribution setting to **Default**.

**Solution 2: Check your default attribution setting**

If your Ad set has the same attribution setting as your query and the discrepancy is still there, reset the attribution setting in your query to **Default**.

If you don't see **Default** as an option, your instance of the Facebook Ads data source might be out of date. To fix this, add a new Facebook Ads data source. Remember to rename the old one before you do this, so you don't have two Facebook Ads data sources with the same name.

****Queries using custom conversions****

****Queries using inline attribution metrics, including Outbound clicks and Video watch %****

If you're finding discrepancies between your reported Facebook Ads "Outbound click" or "Video watch %" data and the data you see in Supermetrics, adjusting your attribution settings can help resolve the issue.

This problem, and its solution, continue to evolve as Facebook adjusts to [changes it made following the iOS 14 update](/v1/docs/facebook-ads-and-ios-14-what-you-need-to-know) in early 2021.

**Solution: Set the conversion window to "Default"**

[A conversion window](/v1/docs/facebook-ads-fields) defines the period of time during which a logged conversion occurs. Often, resetting this field to "default" can help remove discrepancies.

**Google Sheets**

1. Open the Supermetrics sidebar in your Sheet.
2. Open the query you'd like to change.
3. Go to **Options**.
4. In the **Conversion window** drop-down, select **Default attribution**.
5. Click **Update query**.

**Data Studio (formerly Looker Studio)**

1. Click the element you'd like to edit in your Data Studio report.
2. Click the **edit icon (pen icon)** and select the **Facebook Ads** data source.
3. Click **Edit connection** in the upper-left corner.
4. Scroll down to the **Conversion window** drop-down.
5. Select **Default attribution**.
6. Click **Reconnect**.

**Excel**

1. Open the Supermetrics sidebar.
2. Open the query you'd like to change.
3. Go to **Options**.
4. In the **Conversion window** drop-down, select **Default attribution**.
5. Click **Get data**.

**Power BI**

1. On the [Supermetrics Hub](https://hub.supermetrics.com/), go to **Power BI** under **Analyze**.
2. Select the query you'd like to modify.
3. Select a connection.
4. Go to **Options**.
5. In the **Conversion window** drop-down, select **Default attribution**.

**Supermetrics API**

1. On the [Supermetrics Hub](https://hub.supermetrics.com/), go to **API queries** under **Manage**.
2. In the **Query** tab, go to **Options**.
3. In the **Conversion window** drop-down, select **Default attribution**.
4. Rerun the query.

**Data warehouse and cloud storage**

1. On the [Supermetrics Hub](https://hub.supermetrics.com/), go to **Table Manager** under **Manage**.
2. Select the table group to modify.
3. Go to **Options**.
4. In the **Conversion window** drop-down, select **Default attribution**.

****Queries without Campaign/Ad set/Ad dimension that use Default attribution****

Supermetrics queries use unified attribution by default, requesting offsite conversions — like Leads, Purchases, and custom conversions — at the account level. If you use multiple different attribution settings and you attempt aggregate all account's results into one figure using Default attribution, Supermetrics gives the same blank result as the Facebook API would.

This happens because [Facebook doesn't allow](https://www.facebook.com/business/help/861727694396009) offsite conversion aggregation across different attribution windows, and the data Supermetrics returns (with unified attribution) matches the Ad Manager UI.

****SKAdNetwork campaigns****

SKAdNetwork campaigns use an attribution setting that Apple provides. They can't be adjusted, so for this campaign type it's important to set the conversion window setting to "Default attribution". If this setting isn't chosen, the conversion data will come back as zero.

If you have mixed campaigns — SKAdNetwork and non-SKAdNetwork in the same account — consider filtering for those to ensure the settings align:

*Is Campaign using SKAdNetwork EQUALS true*
