Known Issues

This section lists issues we are currently aware of which are considered significant, and which could impact the functionality of your build. We highly recommend reviewing this section before every upgrade.
Module Issue To be resolved in


ONE-34903: You currently cannot set up email notifications about created tasks.



ONE-44522: In PostgreSQL-based MDM solutions, a performance slowdown is possible, which might affect draft publishing speed.



ONE-41271: The MANTA lineage tab is not working properly for catalog items imported from the Oracle source.



ONE-42000: Profile and DQ Insights screen is not dynamic and needs a refresh to present the changes after deleting a term.



ONE-41895: Full-text search does not work for the custom entity as a navigation item on the listing view.



ONE-44708: Previews do not work for Tableau.



ONE-48553: Cannot delete a data source with MANTA integration enabled.

To resolve this issue, make sure the MANTA integration is disabled before deleting the source.


ONE Data

ONE-42387: If data quality filters are applied, you cannot update attribute values in bulk (Multi-edit values option).


ONE Data

ONE-41741: If importing a dataset (for example, a catalog item or a file) fails, a table is created in ONE Data containing no or partial data. This prevents you from reimporting the dataset under the same name as the table name must be unique.

To import the dataset using the original name, delete the table first and then try importing again.


ONE Data

ONE-41765: If reports are imported to Catalog and the user changes the folder name (workspace/project name) directly in Power BI or Tableau and tries to refresh metadata by importing the reports again, the import fails.


Known Issues Resolved

We report known issues in each release. Below is the list of the issues that have been resolved across the platform for this version.

Module Issue Reported in


ONE-34903: You can now automate creating and resolving tasks.



ONE-41649: You can now create SQL catalog items if you have the appropriate access level.



ONE-40708: Invalid samples are now available in monitoring projects with demo data.



Your choice to refuse analytics cookies is now correctly saved in all environments.




Stewardship is now the primary solution for managing data asset ownership in ONE. You assign ownership of your data assets to groups, after which appropriate levels of access to the asset are assigned to the members of the group depending on their governance role.

Once selected, the owner group is represented in the Stewardship widget on the Overview tab of the asset with the list of users assigned to relevant governance roles. You can also view and filter listing screens based on the Stewardship column.

ataccama 14.3.0 stewardship widget

We highly recommended assigning stewardship on all of your existing data assets as it brings the following advantages:

  • Clear visibility of ownership on asset level including individual group members and their roles.

  • Automatic configuration of access levels within the owner group.

  • Reduced need for manual assignment on assets with hierarchy because of top-down inheritance of ownership.

For detailed information, see Stewardship.

If you use Owner and Steward fields available on data assets to define ownership, we recommend that you use these fields for reference when upgrading. These fields are obsolete and may be removed in the future.

New installations of version 14.3.0 no longer contain these custom fields on any data assets. If you are upgrading to 14.3.0 from an earlier version and wish to reuse this information for assigning stewardship, you need to export these fields from the earlier version and import them to the new version once set up.

For information about how to do this, see ONE Gen2 Upgrade Guide, General Notes section.

Stewardship in Tasks and Workflows

With the new stewardship concept, access request tasks are automatically assigned to the owner group of the asset the access was requested for and its respective governance roles. You can manage how stewardship is automatically assigned by configuring the Request Data Access workflow. For more information, see Workflows.

Tasks of other types can now also be assigned not only to a particular user but to a group and its governance roles. For more information, see Tasks.

Custom Landing Pages

ONE now comes with a default home page that all users land on when they log in to the application.

ONE administrators can customize this page and create secondary landing pages and share them with groups and individual users. For more information, see The Home Page.

Improvements to Metadata Anomaly Detection in Catalog

It is now possible to select whether you want time-independent or time-dependent anomaly detection to be used during profiling. For more information, see Anomaly Detection in Catalog Items.

ataccama 14.3.0 release notes anomaly detection in data catalog
The minimum required number of profiling runs for time-independent anomaly detection has been increased from 3 to 6. Time-dependent anomaly detection also requires a minimum of 6 runs.

The anomaly detection on profiles has been improved to identify previously hard-to-detect anomalies more effectively and to reduce the overall number of false positives.

The model is now better equipped to detect unexpected nulls, unexpected negative or positive values, unexpected zero values, and changes from established trends. Regarding false positives, values identical to those previously dismissed as not anomalous are no longer flagged, and values are no longer flagged based on frequency if no significant key or changes are detected. The low-sensitivity options are now even less sensitive, so altering the anomaly detection sensitivity can help if false positives persist.

Term Notifications in Data Observability

Get notified when new terms are detected in your observed system or when existing terms are newly added to attributes. You can also enable notifications for when terms are applied manually.

Term notifications are configured within the Advanced configuration flow for observed systems. For more information, see Data Observability.

ataccama 14.3.0 release notes send me term notifications

Check notifications in the issues table in the data observability dashboard. From here, you can also add newly-found terms to the list of observed terms or review term suggestions.

ataccama 14.3.0 release notes check term notifications

From the data observability dashboard, you can then add the terms to the observed system or accept the term suggestion accordingly. For more information, see Data Observability Dashboards.

Using basic configuration, you are alerted by default when new terms are detected in the source or when terms are newly suggested on observed catalog items.

Improvements to Listing of Observed Systems

You can now see the status of all observed systems after selecting Data Observability in the left navigation menu. Filter the selection by connection type, catalog item count, observability status, observability monitoring, and stewardship, as well as according to the selected timeframe (such as day, week, month). Use the icons to switch between table view and list view.

Support for Tableau and Power BI in Reports

We now support working with reports from Tableau and Power BI in ONE. To import reports from these BI tools to ONE, make sure that all the prerequisites are met. For more information, see Reports from Tableau and Reports from Power BI respectively.

You can also manually document reports, sources, or datasets from BI tools other than Tableau, PowerBI, and Data Stories by creating a generic report and using your BI tool’s APIs. However, the functionality of these reports depends on the BI tool connection options and might be limited. For more information, see Reports from Other BI Tools.

Support for Databricks Unity Catalog

We have added support for Databricks Unity Catalog for new data sources. Databricks Unity Catalog provides a unified approach to governing your data and AI assets across Databricks workspaces, along with centralized access control, auditing, lineage, and data discovery capabilities. In Unity Catalog, data assets are organized in three levels, starting from the highest: Catalog > Schema > Table, allowing you to work with multiple catalogs at once. For more information, see Databricks Unity Catalog Connection.

Currently, Databricks Unity Catalog cannot be enabled on existing Databricks connections.

Also, we only support Unity Catalog with single user access mode enabled, not with shared.

ONE Data

Invalid Records Export and DQ Filters for Improved Data Remediation

ONE Data is now better equipped to assist you with data remediation.

Easily export all invalid records from a catalog item to ONE Data using the Data Export feature. Once you select the catalog item for export, choose Invalid records instead of All records. Before your table is created, DQ evaluation runs on the whole table. For more detailed instructions, see Create a Table, section Import from catalog item.

You can also export invalid records from an observed system in the Data Observability module, see Data Observability Dashboards.
ataccama 14.3.0 release notes export invalid records

When your data is imported, use the new data quality filters to quickly find specific data quality issues in your table. Filter by entire DQ dimension, DQ rule, or a specific condition within a rule. In addition, filters can apply to a specific attribute, all attributes, or any. For more details, see Filters.

Improvements to Optimistic Locking and Error Handling

In addition to adding or removing attributes, optimistic locking is now also applied when duplicating, renaming, or reordering attributes. Your changes are only saved if the table structure hasn’t been modified by another user in the meantime. Otherwise, you need to load the latest changes first before continuing.

ataccama 14.3.0 release notes get oriented with one data optimistic locking

To help you understand why your change is not accepted and maintain the integrity of the data displayed, we have also introduced more robust error handling. In case an issue occurs, for example, if the table is locked due to a long-running operation or the attribute name already exists, follow the instructions displayed in the application to solve it.

Auditing in ONE Data

User actions from ONE Data can be monitored in the Audit module. Explore audit logs directly in ONE (Audit tab), or using the dedicated Audit API. To learn more, see Audit and Audit API respectively.

For ONE Data, the following actions are audited:

  • Metadata changes, such as:

    • Creating or deleting a table.

    • Adding, renaming, reordering, or deleting an attribute.

  • Accessing data.

  • Editing data, such as:

    • Adding, editing, or duplicating records.

    • Duplicating an attribute.

Operations related to ONE Data use the prefix [ONE Data].

Self-Managed Deployment Available

In addition to Ataccama ONE PaaS solution, ONE Data can now also be deployed in self-managed, virtual machine-based solutions using Ansible.

Data Stories

We have introduced several UI improvements and changes to enhance the user experience. Users can now define custom names for axis labels in the Story Editor and move steps to another section with ease. We have renamed Reports and Dashboards page to Reports and updated the home screen dashboard to show more relevant information. We have also removed certain features like the Section height customization option and Line time comparison chart, as they were not meeting the needs of all users. Finally, we have redesigned the navigation in the Story Editor to make it more intuitive.

See the following sections for a breakdown of all changes included in this release:

UI Enhancements

  • Filters functionality for widgets in Data Explorer and Story Editor has been updated and given a new, modern look, making it easier for users to filter and manipulate data.

    ataccama 14.3.0 release notes filter in widgets
  • The Story Editor UI has been updated, including repositioning of Add a step button and a different icon.

  • To make it easier to navigate the application, Reports and Dashboards page has been renamed to Reports.

Story Editor Updates

  • Use the new Move step button in the Story Editor to move steps between sections. This makes it easy to organize content and ensure that the story flows smoothly.

  • For simplified data organization and labeling, you can now define custom names for Axis labels using the Step properties section.

  • Section height customization option has been removed from the Story Editor.

Additional Updates

  • Line time comparison chart has been removed from widget options in Story Editor, Dashboard Editor, and Data Explorer as we reconsider how we approach period-over-period comparison (through configuration rather than a specific chart type).

  • The dashboard in Data Stories home screen now shows Number of stories, Number of explorations, and Number of dashboards, replacing Number of views by Number of explorations, which gives you more meaningful information about your reports.


Automatic Task Creation

Automatic task configurations tab can be accessed from the left navigation panel.

The functionality can also be turned off, and you can enable and run the creation process manually (for example, in case the filters need to be reviewed by other team member first).

You can view automatically created tasks on the Tasks or My tasks tab along with manually created tasks. For more information, see Automatic Task Configuration.

Upgrade Notes

To determine your upgrade path, see MDM Upgrade Procedure and MDM 14.3.0 Upgrade Notes.



We have introduced a native REST API for RDM, allowing you to read metadata and data from your RDM instance using REST interfaces. This way, you can retrieve the application status and configured data models, or list table records using basic or advanced filtering options.

In addition, you can use the API to generate an encoded link to a specific record for easier sharing.

To learn more, see RDM REST API.
