    Analytics Features

    Period and organisation unit drill-down

    The Pivot Table app now supports drill-down (and up) for periods and organisation unit. This means that you can, for example, drill down from yearly periods to quarters, months and weeks inside the pivot table. You can also drill down from the global organisation unit to countries, provinces and facilities.

    Organisation unit levels as columns

    When downloading a pivot table with organisation units as rows and the “Show hierarchy” option enabled in the options dialog, each organisation unit level is rendered as a separate column. This is useful for example when you create Excel pivot tables on a local computer.

    Row and column % in pivot tables

    In the Pivot Table app you can now display values as percentages of row total or percentage of column total (instead of the aggregated value). This is useful in order to see the contribution of data elements, categories and organisation units to the total value. You enable this in Table options dialog.

    Hide missing values handling

    The Data Visualizer app now offers better control over hiding of missing values. You can choose between “Before first value”, “After last value” and “Before first and after last value”. This is useful for example when creating column and bar charts. You enable this in the Chart options dialog.

    Demo][ Screenshot ] [Docs]

    EPI weeks

    The system now supports various weekly period types, with Monday, Wednesday, Thursday, Saturday and Sunday as the first day of the week. Data can be collected through data sets configured to use the desired weekly period type. The analytics engine will attribute weekly data to the month which contains four days or more of the week.

    Demo ][ Screenshot ] [Docs]

    Group set flexibility

    Data element groups and organisation unit groups can now be be part of any number of group sets. This allows for increased flexibility in analysis. This change also allows for persisting the “All items” checkbox as part of favorites in analytics apps.

    Attribute option combos in indicators

    You can now specify data elements together with attribute option combinations in indicator expressions. This is useful e.g. to compare targets vs results, or the performance of various programs in indicator calculations. UI support is not yet there, attribute option combos can be entered directly in the expression, see the docs.

    Demo ][ Screenshot ] [Docs]

    Reporting rates in indicators

    Indicator now allows for specifying reporting rates and actual reports in expressions. This is useful e.g. to adjust for data completeness in performance indicators. UI support is not yet there, reporting rates can be entered directly in the expression, see the docs.

    Favorites and interpretations in event analytics apps

    The new, file-based favorite solution has been introduced in the Event Reports and Event Visualizer apps, similar to the solution in for example the Pivot Table app. This means that you can now also create and share interpretations for event reports and event charts.

    Demo ][ Screenshot ] [Docs 1 | Docs 2]

    Program category dimensions in event analytics apps

    The Event Reports and Event Visualizer apps let you use program categories and category option group sets as dimensions for tables and charts. This applies for programs with category combinations.

    Demo 1 | 2 ][ Screenshot ] [Docs 1 |2]

    Multiple legend sets per data element

    In Event reports and Event Visualizer apps you can aggregate events by multiple legend sets per data element. This becomes useful with age groups, for example. You can collectage in years as part of an event and then aggregate into various age groups such as by 10 year intervals or 15 year intervals. This way, data can be collected once and later used to satisfy multiple reporting needs.

    Demo 1 | 2 ][ Screenshot 1 | 2 ] [Docs]

    Program and event status

    You can now filter data by program status and event status in the Event Reports and Event Visualizer apps. You can set these filters from the options dialog.

    General Features

    Sharing dialog

    A new dialog for sharing of metadata is now available in the Maintenance app, offering a better and simpler user experience.

    Demo ][ Screenshot ] [Docs]

    Notification modes

    Validation rule notifications can now be sent as individual messages or as message summaries. This is useful e.g. when you want to send individual messages for high-priority disease outbreaks, and summaries for low-priority routine data validation errors.

    Demo ] [Docs]

    Sliding windows in validation rules

    Validation rules can now calculate data based on sliding time windows. This implies that data is evaluated not just for fixed periods, such as weeks, but also for sliding intervals of the same duration, e.g. Wednesday to Thursday.

    Demo ] [Docs]

    Improved password security

    The system now provides greater security and control over passwords. To enable this go to System Settings > Access.

    • Email notifications can be sent out to users 14 days before their password expires and must be changed.
    • The minimum number of characters in passwords is configurable and can be between 8 and 14.
    • Password must contain a mix of at least three characters from the following categories: uppercase, lowercase, numeric and special (non-alphanumeric).
    • When changing passwords, users cannot use any of the 24 previously used passwords.

    Cloud storage for resources

    Resource (files and links, found in the Reports app > Resources) can now be configured and be backed by a cloud storage provider such as AWS S3. This allows for infinite storage of files. This requires that you’ve configures a cloud store in dhis.conf.
    Note: if you’ve configured cloud storage in dhis.conf, all files you upload or that the files system generates, will use cloud storage, not only resources.

    Data store manager

    A new app is available which lets you manage the content of the web API data stores. This is helpful when managing apps and external scripts.

    Tracker Features

    Program rule improvements

    A completely new user interface for managing program rules has been introduced in the Maintenance app. A range of new program rule actions is now supported in the new user interface:

    • Assign value. Enables client side calculations.
    • Display text. Enables the web client to display text in the indicator or feedback widgets.
    • Display key/value pair. Enables the web client to display a information box with a title and value in either the indicator or feedback widgets.
    • Make field mandatory. Enables program rules to turn a field mandatory based on rule expression.

    Other improvements include the ability to delete and change program rule variables (source fields), and the ability to include one data element in several program rule variables. For all warning and error messages it will now be possible to include a dynamic/calculated part at the end of the static error message.

    You can now use memcached as an application cache provider. This allows for greater scalability as memcached can be hosted on a separate server off-heap.


    WEB API Features

    Tracker soft delete

    Soft deletion has been introduced for the tracked entity instance and enrollment entities. This gives clients with local databases the opportunity to react on deleted entities.


    Deleted metadata objects log

    Deletion of metadata is now logged and can be queried from a new endpoint /api/deletedObjects. This allows clients with local databases to react on deleted metadata objects.


    Email sending

    A new endpoint for sending email is introduced at /api/email.


    Min-max data element values

    A new endpoint for setting and retrieving min-max data element values is introduced at /api/minMaxDataElements.
