Troubleshooting alerts

Last updated: 10/16/2026

This section describes problems that can occur when using alerts.

The preview could not be generated

You get a message The preview could not be generated when creating the alert.

Possible cause  

You have access to the application as a tenant or analytics admin but you do not have access as a user.

Proposed action  

You need to get at least viewing permissions to the application to be able to create alerts. Request viewing permissions from the application owner.

No access to application

The message No access to app is displayed under Application in the alerts overview.

Possible cause 1

You do not have permission to view the application.

Proposed action  

Contact the tenant or analytics admin to get at least view permission to the application.

Possible cause 2

The application has been deleted.

This alert would not trigger with the current data

In Preview, you get the message This alert would not trigger with the current data when creating an alert.

Possible cause 1

The conditions are not met by the current data. This is expected behavior, not an error.

Proposed action  

Check the conditions you defined and compare them with the values in Preview data. Adjust the conditions if the alert should trigger. For more information, see Setting conditions for alerts.

Possible cause 2

The label of a measure is a text expression that contains two quoted segments, for example ='Total' & Chr(10) & 'Sales'.

Proposed action  

Change the label expression so that it uses a single set of quotes, or simplify the label.

Possible cause 3

The community has published a workaround for chart labels that contain an equals sign (=): Alerts in Qlik Cloud are not working as expected: this alert would not trigger with the current data.

Alert email notifications are not received

An alert is triggered, but you or the recipients do not receive the email notification.

Possible cause 1

The alert is disabled, or notifications for the alert are snoozed.

Proposed action  

In the Alerts page, enable the alert if it is disabled, and check whether Snooze notifications is on. For more information about enabling and disabling alerts, see Managing your alerts.

Possible cause 2

Email is not selected as a notification method for the alert or in your global notification settings. You might have selected Daily email digest instead.

Proposed action  

Check the notification settings. For more information, see Customizing alert notifications.

Possible cause 3

The alert evaluation fails if a recipient does not have view permission for the application. If the application uses section access, evaluation also fails if a recipient cannot access the data used in the alert selections. The sheet must be public for recipients to open it from the notification.

Proposed action  

Give each recipient view permission for the application. If the application uses section access, make sure each recipient can access the data used in the alert selections. Make the sheet public if recipients need to open it from the notification. For more information, see Monitoring data with alerts.

Possible cause 4

Email support is not configured for the tenant, or data alerts are not enabled.

Proposed action  

Ask a tenant admin to enable data alerts and configure an email server. For more information, see Enabling and managing data alerts and Configuring email for reports and notifications.

Limitations

Data is limited to 100,000 rows

When the alert is evaluated the data set is limited to the first 100,000 rows of the returned hypercube. This means that it will not evaluate on the full data set or provide a complete result.

If you have a large data set, the workaround is to create multiple alerts with a filter to reduce the number of rows in the data set to evaluate.

Email notifications are limited to 10 rows of data

If the result of the alert evaluation contains more than 10 rows of data, the email notification only shows the first 10 rows.

There is also a CSV file with all rows of data attached to the email. Do not open the CSV file directly in Excel. As the fields are delimited with Tab characters and Excel expect commas, it will not be correctly formatted. To open the CSV file:

1. Download the CSV file to your computer.

2. Open Excel with a blank workbook.

3. Import the CSV file using Tab as delimiter.

You can have up to 50 alerts

The number of alerts that you own or subscribe to, is limited to 50. Disabled alerts also count towards the limit. If you have reached the limit you can reduce the number of alerts.

• Delete alerts that you own.

• Unsubscribe from alerts that have been shared with you.

Sharing alerts based on applications with section access

If the alert is based on an application that uses section access to manage user access, you can share the alert with up to 100 recipients.
