# Managing applications

## Permissions <a href="#permissions" id="permissions"></a>

### Creating applications <a href="#creating-applications" id="creating-applications"></a>

Both users with the **Create Applications** permission and global administrators can create applications:

* **Create Applications permission** – Users with the **Create Applications** permission (granted at the global level at **Administration** > **Security** > **Global Permissions**) can create applications by clicking the **Create Application** button in the upper-right corner of the **Projects** homepage.
* **System Administrators** – In addition to creating applications from the **Projects** homepage, system administrators (with the **Administer System** permission granted at **Administration** > **Security** > **Global Permissions**) can create applications from the overall portfolio administration interface at **Administration** > **Configuration** > **Portfolios**.

### Editing Applications <a href="#editing-applications" id="editing-applications"></a>

Users need to have either **Administer** permissions for any applications that they want to edit (set on the specific application’s page at **Application Settings** > **Permissions**) or the global **Administer System** permission.

{% hint style="info" %}
Users with **Administer** permissions for an application can see the list of projects that make up the application even if they don’t have browse permissions for those projects.
{% endhint %}

### Changing the PDF report frequency <a href="#changing-the-pdf-report-frequency" id="changing-the-pdf-report-frequency"></a>

As an application administrator, you can change the PDF report subscription frequency of the application:

1. Retrieve the application.
2. Select **Application Settings** > **Application Report Settings**, and select an option from the **Application Reports Frequency** drop-down menu.

You have the following options for subscription frequency:

* **Daily**
* **Weekly**
* **Monthly (default)**

## Populating applications <a href="#populating-applications" id="populating-applications"></a>

Once your application exists, you can populate it with manually selected projects by going to *Your application* > **Application settings** > **Edit definition**. By default, the configuration interface shows the list of projects currently selected for the application. To add additional projects, choose the **Unselected** or **All** filter.

## Creating Application Branches <a href="#creating-application-branches" id="creating-application-branches"></a>

Once your application is populated with projects, you can create application branches by choosing branches from the application’s component projects. This option is available in *Your application* > **Application Settings** > **Edit Definition** interface or from the global administration interface.

## Calculation <a href="#calculation" id="calculation"></a>

By default, applications are queued to be recalculated after each analysis of an included project. For each relevant application, a **Background Task** is created, and you can follow the progress on each in the **Administration** > **Projects** > **Background Tasks** by looking at the logs available for each item.

## Reindexing <a href="#reindexing" id="reindexing"></a>

During Elasticsearch reindexing due to disaster recovery or upgrading, applications become available as they are indexed. See [reindexing](https://docs.sonarsource.com/sonarqube-server/server-update-and-maintenance/maintenance/reindexing "mention") for more information.
