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


ONE-48932: Very rarely, when trying to view changes in a review request, the published version and changed version both appear blank.


ONE-45718: Trying to delete the draft of a business term after creating a publish request and associated task causes the deletion to fail. Attempts to approve or reject the business term generate errors.


ONE-47632: Very rarely, when deleting a term using the three dots menu, the workflow bar fluctuates between Edited and Deleted states.


ONE-48631: Rarely, after you submit a review request for a term, the workflow bar incorrectly displays View review request instead of the expected Review and publish.


Generative AI in ONE

These are experimental features which are only available in Ataccama Cloud deployments.

Leverage OpenAI in Ataccama ONE to generate SQL queries and ONE expressions from text prompts, write catalog item descriptions, or provide plain text explanations for existing SQL queries.

Generate expression

All features can be enabled or disabled from Global Settings > OpenAI.

Data Transformation Plans

Transform data in ONE using the new data transformation plans. This facilitates two key use cases:

  1. Transformation of data quality monitoring project results. In this way, data transformation plans supersede post-processing plans.

  2. Standalone data transformation of catalog items.

Once you have configured your data input (catalog item or monitoring project results), you can then add a number of steps, such as filter, split, join, or transform, and add or delete attributes.

Each step represents a data processing job. After transformation, export data to ONE Data or to files in ONE Object Storage, or use it in another plan. You can preview data and validate expressions in real time when working with data transformation plans.

Transformations example flow

Previously, such transformations had to be executed in ONE Desktop. For more information, see Data Transformation Plans.

Data Remediation Plans

Using data remediation plans, users can load data, metadata, and DQ results from monitoring projects into ONE Data for data remediation.

Data remediation plans are located under Data Quality > Transformation plans and utilize the same plan canvas design as transformation plans, but the predefined data remediation output step writes the term and rules metadata from catalog items to ONE Data: the ONE Data writer step used in transformation plans does not copy information about assigned terms or rules. The remediation step also stores DQ results in ONE Data, meaning you can view DQ results and also filter by DQ results.

The data remediation output is designed for the specific use case of import of issues for manual resolution.

For more information, see Data Remediation Plans.

Monitoring Project Import Improvements

Previously, if you wanted to test new rules on a catalog item in a monitoring project without risking unnecessary changes in a production project, it was necessary to create a separate monitoring project and test the changes there. Now, you can import only the selected catalog items as well as replace them with alternatives.

Select catalog items for import

Furthermore, on the attribute level, you can remap attributes (provided the new mapping fulfills data type constraints) or ignore selected attributes in the import.

Map attributes

Invalid Data Samples for Catalog Items

For catalog items, you can now see samples of the data that failed the data quality evaluation - invalid data samples. Seeing specific records that failed the DQ rule speeds up the investigation of data quality issues and fixing the data.

To use this feature, first, enable invalid samples on your catalog item, and after running DQ evaluation, straightaway access the invalid sample. See Invalid Samples.

To use this functionality, storing of invalid samples for catalog items must be enabled on a global level. This can be done only by admin users. For more information, see Retention Settings, section Set retention period on invalid data samples.
Show invalid samples
List of invalid samples

Configurable Global Retention Policy for Catalog Items and Monitoring Projects Results

In ONE, you can now configure a global retention policy for the results of monitoring projects and results of data quality evaluation on catalog items.

You can separately set retention for the following:

  • Results of monitoring projects (previously configurable only via API).

  • Results of data quality evaluation on catalog items.

  • Invalid samples for catalog items, that is, the samples of records that have failed the data quality evaluation on the catalog item.

Retention period can be based on days or runs—​results older than the defined number of days or runs are deleted.

Retention settings overview

Custom File Import

Data engineers need to be able to configure file import settings in an object or file storage connection so that all CSV and Microsoft Excel files imported and processed properly. Custom file import allows for customization of CSV and Microsoft Excel file import settings for individual files, folders or whole connections.

Previously, the platform attempted to detect the file parsing options and header rows, but it was necessary to override the detected parameters in some cases. The previously available autodetection without any customizability prevented the import of such files.

For more information, see Custom File Import.

Custom file import settings

Support for Power BI Report Server

In addition to the cloud-based Power BI solution, you can now also connect to the on-premise Power BI Report Server. A new connector has been added for this purpose.

For more information, see Power BI Report Server Connection.

Support for Tableau Server

In addition to Tableau Cloud, you can now connect to Tableau Server. For details, see Tableau Connection.

Term Suggestions Overview

We have streamlined how term suggestions are presented in ONE. You can now see, approve, and reject them from a single location.

To do this, go to Knowledge Catalog > Term Suggestions.

Select a term suggestion to view more details before making your decision.

Read File Variables Task Extended and Write File Variables Added

The Read File Variables task in ONE Desktop was extended to support not only property files as inputs but also text files (lines or whole file).

There is also a new task, Write File Variables, to write values (typically contents of variables) into property or text files.

ONE Data

Overwrite Existing Tables

When loading data to ONE Data from another catalog item in ONE, you can now overwrite an existing table instead of creating a new one. To do this, select Overwrite existing ONE Data table and choose the table you want to replace.

Overwrite existing tables

Keep in mind this deletes all existing data from the selected table. For more detailed instructions about importing data to ONE Data, see Import Data from a Catalog Item.

Stewardship in ONE Data Tables

Manage access to ONE Data tables through stewardship, the primary solution for handling data asset ownership in ONE.

We recommend assigning ownership of your tables when creating a new ONE Data table to prevent any unauthorized access. If it is not set on the table level, the stewardship configuration is inherited from the data source.

If you are creating a table from scratch instead of loading an existing catalog item or importing a file, change the stewardship from the table Overview tab.

Allow Loading to ONE Data

All data sources can have data loading to ONE Data turned on or off as required. On a source connection, use Enable exporting and loading of Data.

Enable exporting and loading of data

Load to ONE Data

Load to ONE Data is now a standalone action, independent of Export. Use the three dots menu and select Load to ONE Data.

Load to ONE Data

There is also a shortcut to load only failed records from the Data Catalog to ONE Data:

  • On the catalog item Overview tab, locate the Data Quality widget. Use the three dots menu, and select Load failed records to ONE Data.

    Load failed records
  • On the catalog item Data Quality tab, select Load failed records to ONE Data.

    Load failed records
    This option is only available when you are viewing the Latest results.

UX Improvements

To make working with ONE Data even easier, we have introduced the following:

  • You can now fill in multiple cells at once. To do this, when pasting, select an array of cells (spanning one or several columns) instead of a single one.

  • If you select Any or All attributes when filtering records, the filter automatically finds records that failed all DQ rules until you change the filter settings.

  • If you are importing catalog items with component or aggregation rules applied, these rules are not imported to ONE Data and cannot be used in filters. You can see whether the catalog item has any such rules applied during the import process.

  • When a record fails DQ evaluation, the tooltip on the record now includes an explanation about why it failed.

    Failed rules

Data Stories

These are the key updates introduced in the latest version of Data Stories:

  • We have improved the Cumulative Sum function, ensuring it seamlessly integrates with Multiseries charts. When using this feature in the visualization builder, you no longer encounter validation errors.

  • The name of the source catalog item or Data Quality (DQ) result is now prominently displayed right above the raw data in the table in Data View. This gives you a clearer reference to your data source.

  • We’ve renamed the Top N feature to Top/Bottom Values and refreshed the UI. An added tooltip briefly explains how it affects your visualization results.

  • You can now effortlessly copy visualizations across different collections. Select Copy from the three dots menu next to the visualization, then choose the target collection.

  • Visualization names are now displayed directly in the pop-up editor when editing a visualization from the Report Builder, whether it’s a dashboard or story. Thanks to this, the editing process is smoother and you don’t need to navigate away from the task at hand.

  • In both the Story and Dashboard editors, the side panel containing Collections and Visualizations is now resizable. This allows you to adjust the panel size to suit your workflow and needs.

  • We’ve updated the navigation bar in the Visualization Builder for a sleeker design. The Home tab is now distinctly separated from other visualization tabs.

  • Using the Create option on Reports and Home pages you can now create only Dashboards or Stories but not Visualizations.

  • You can now enhance your Line Charts (both Single and Multiseries) with the new Show boundary gap setting. This feature positions axis labels in the center of the band delimited by two axis ticks, offering a clearer way to present your data.

  • Both KPI and Gauge Charts now feature segmentation capabilities. Enabling Show segments divides the progress bar into distinct segments, aiding in tracking progress towards multiple milestones. Customize these segments with different colors and completion rates, and easily add new segments (Add segment option).

  • Data Stories is now more accessible with added localization support for Czech, German, French, and Italian language.

  • The color picker has been improved to offer a richer selection of colors in the default scheme. You can now easily assign custom colors to each dimension value.

    Hover over and select the three dots menu next to a value to reveal the available options, including Standard colors, Ataccama colors, and a Custom color selection tool.


Database Performance Optimization

We have introduced two features that help improve the database performance of PostgreSQL databases from the MDM Web App Admin Center.

Database Monitoring

You can now download a ZIP file containing essential database information, for example, database monitoring logs, Hikari configuration, or DDL script. It serves as a tool for debugging and addressing performance issues. Additionally, you can temporarily (until the next server reboot) change the following logging settings:

  • Show SQL request parameters.

  • Set a minimum duration of a logged SQL request. You can access the functionality from the Database tab in the MDM Web App Admin Center. To learn more, see MDM Web App Admin Center, section Database.


Performance Tuning

You can now download and upload performance settings and retrieve performance statistics to optimize and monitor SQL query performance. You can access this from the Performance Tuning tab in the MDM Web App Admin Center.

To learn more, see MDM Web App Admin Center, section Performance Tuning.


Git Operations

It is now possible to deploy a new configuration from the MDM Web App Admin Center. You can view current configuration and the latest commits, fetch recent changes from the Git repository, apply one of the newer commits, and clone the config repository.

To learn more, see MDM Web App Admin Center, section Server Dashboard.



Changes to Import and Export Dialogs

We have refreshed the Import and Export dialogs in RDM Web App:

  • If you are using custom separators, line endings, or a datetime format, choose Custom. Previously, this option was called Not in list.

  • Date and time can now be specified using a slash (/) as the separator.

  • We have updated the list of supported date and time formats. For more information, see Importing and Exporting Data in RDM, section Import Requirements.
