Dundas BI - Product Notes


1. Overview

The Product Notes for Dundas BI contains information about features that work differently or are currently unsupported depending on the type of data you are working with or other conditions. This includes browser and product limitations.

2. Browser

Internet Explorer

Beginning January 12, 2016, Microsoft stopped feature development on Internet Explorer and has been releasing only security updates. Due to inherent limitations and no further development, Internet Explorer may experience reduced performance when compared to other browsers and is not recommended.

A significant example is a memory leak created in Internet Explorer during navigation. Depending on the system memory, this may cause the browser to crash when enough memory has leaked. This issue is not limited to Dundas BI and is present during every navigation performed using Internet Explorer, but may surface faster with heavier implementations. To avoid this particular issue, open a new window instead of navigating to the desired URL (Ticket 66060). 

Changes made in the Filter Visualizations popup may not be saved after closing Internet Explorer (Ticket 39288).

When double-clicking on a label component to edit its text, a Webpage Error (JS error) may occur in Internet Explorer. This happens under very specific circumstances but does not interfere with the work flow. Simply click elsewhere and click on the label again (Ticket 51116).

Support for Internet Explorer 11 is primarily maintained for viewing dashboards, reports, and other views, including options and interactivity accessible from view mode (Ticket 88138).

Internet Explorer,
Edge Legacy
Table visualizations displaying many tens of thousands of rows or more may not scroll to the correct position.

In older versions of Safari, the login fields may not be visible when accessing Dundas BI using Safari's Private Browsing mode.

Safari now has the Prevent cross-site tracking privacy option enabled by default which may cause problems loading Dundas BI when embedded and viewed in an iframe on a different domain. In this case users must click the Enable Application button in the iframe to access Dundas BI. (Ticket 80774)

Safari versions prior to 13 (including iOS before version 13) do not correctly handle cookies with the SameSite header set as None, which can cause issues embedding Dundas BI on different domains over HTTPS. This was an issue in Safari fixed only in versions 13 and up. (Ticket 83769)

Google Chrome,
Edge version 77+

When viewing the dashboard in Re-size mode, scrollbars may randomly appear in the browser. This is a known issue with the browser and is being investigated by the Chromium team. To remove the scroll bars, resize the dashboard (Ticket 57933).

When selecting or editing an image Source property containing a very long string, the browser may freeze. This is a known issue with the browser and is being investigated by the Chromium team. To avoid the situation, upload the image into Dundas BI (Ticket 60230).

Using a Chromium-based browser, holding the Shift key prior to dragging elements will not work (Ticket 71320). This is a known issue with the browser that can be avoided by holding Shift after pressing the mouse button while dragging rather than before.

Embedding Dundas BI as an HTTP site in a cross-domain or cross-origin environment is not supported due to changes in Google Chrome. (Ticket 83769) Similar changes are tracked here for Microsoft Edge. To use an embedded instance of Dundas BI from a different domain or origin, ensure that your site can run on HTTPS.

Firefox When viewing a scaled dashboard in Firefox and clicking a drop down list, the drop down menu may be incorrectly positioned. This is due to a Firefox bug (Ticket 50600).

3. General / Application

logon If you have multiple instances of Dundas BI running on the same server, and the paths to these instances differ only by the port number, users will be logged out automatically when they navigate from one instance to another instance and log on. Returning to the previous instance requires the user to log on again. 41499
embedding Embedding Dundas BI on another webpage and applying the CSS display: none to the Dundas BI element or iframe will cause the browser to load the application without allowing its elements to render correctly. Dundas BI should be loaded when displayed, or you can use the alternative CSS visibility: hidden. 87106
user interface If your web browser has a plugin installed that adds a toolbar or occupies a portion of the browser real estate, this will affect the coordinate system of Dundas BI and can result in various UI issues. N/A
deployment, Linux Support for deploying and running Dundas BI directly on Amazon Linux 2 has been discontinued. Consider deploying using Docker containers or another Linux distribution instead. 86963

4. Data Preparation / ETL / Analysis

data connectors Discovery of scalar-valued functions and other non table-valued functions is not supported. 40665
data connectors If you edit an existing non-relational or non-OLAP data connector, make some changes to it (e.g., via Define Structure), and then perform a re-discovery, previously discovered structures will remain under the data connector in Explore. If you then try to use these previous structures you may encounter connection errors. 41508, 50426
data connectors, Access Crosstab queries and linked tables are not discovered. The crosstab queries and linked tables are available if using manual queries. Another option is to create parameterless SELECT queries to the crosstab queries or linked tables (which will be discovered as views). 50856
data connectors, ODBC, JDBC

A 64-bit version of the ODBC driver is needed to work with Dundas BI's 64-bit application pool.

Discovery of table and view definitions may not work for some ODBC and JDBC data sources. As a workaround, use data cubes based on manual SQL query.

Discovery of table relationships (e.g., foreign keys) may not work for some ODBC and JDBC data sources.

Stored procedures and functions are not discovered.

41355, 68858
data connectors, SSAS Executing certain valid MDX in SSAS 2012 fails with Internal error: An unexpected error occurred (file 'mdmisc.cpp', line 945, function 'MDBulkSetScaIter::Start'). Try installing SQL Server 2012 SP2 to fix this issue. 50521
data connectors, SSAS, OLAP The DRILLTHROUGH statement and other MDX queries that do not return a cellset are not supported. 69064
data connectors, Microsoft Dynamics CRM Some entities in Microsoft Dynamics CRM are not supported, which may result in an Internal Server Error on the RetrieveMultiple method and prevent certain tables from working. 63329
data connectors, Access and DBF The Microsoft driver used to connect to DBF files does not support FoxPro dBase 3.5. As an alternative, you can use an ODBC data connector to connect to the same files. 66067
data connectors, IBM DB2 The IBM DB2 data provider may not be able to connect to certain versions of DB2 such as AS/400. ODBC or JDBC drivers can be used instead. 73788
date mapping, OLAP If the OLAP hierarchy being mapped has a data gap, using the option to manually set the start date will yield the wrong results. Specifically, years after the gap will be incorrectly mapped. 40681
data cubes, warehouse storage Strings longer than 900 characters (or unlimited length) cannot be indexed, which may cause performance issues when used in a data warehouse. Change the data type to a shorter set length to avoid this issue. 53199
data cubes, warehouse storage The floating point values NaN and Infinity are not supported and will cause the data warehouse build to fail. 53933
data cubes, hierarchies, in-memory storage Previewing a hierarchy in the Hierarchy editor may be slow if the underlying data cube is using in-memory storage. You may get better performance by using warehouse storage for the data cube instead of in-memory. 50414
metric sets, period over period Period over period cannot be added to an existing period over period measure. 50927
metric sets, natural language assistant, Python When Dundas BI is installed on some instances of Windows 10 version 2004 or higher, the Python machine learning engine may fail to start when users try to use the metric set assistant due to a Windows issue combined with NumPy version 1.19.4. Please note that only Windows Server is supported for production installations of Dundas BI.
You can avoid the error by installing NumPy version 1.19.5 or later from the command line on the server (e.g., pip install numpy --upgrade) or with an update to Windows.
metric sets, Oracle Oracle Character Large Object (CLOB) data used with a parameter compares only the first 2000 characters. This may cause extra rows to be returned. 41741
metric sets, OLAP In cases where Dundas BI does the aggregating, you may need to change the aggregator from Provider to a specific alternative to avoid missing values when the measure comes from an OLAP cube. For example: when a formula is added based on the measure and the Collapse All option is used on a hierarchy. 67000
metric sets, dynamic hierarchies, dynamic measures Dynamic hierarchies and measures are not meant to replace editing a metric set for performing analysis, and have more limited filtering and sorting options. 50657
metric sets, dynamic hierarchies, period over period Period over period cannot be used with a dynamic hierarchy selected as the time hierarchy. 50824
metric sets, dynamic hierarchies The No Selection token is provided for dynamic measures only and is not supported for dynamic hierarchies. 57994
formula metric sets, dynamic hierarchies If a dynamic hierarchy is used in a formula visualization, its level should be set the same as in the original metric set. 83469
formula metric sets, expand and collapse The expand and collapse functionality is not supported for hierarchies or members in formula visualizations/formula metric sets. 49485


filtering The Single Number filter should only be used to filter integer data values. To filter decimal type data, use the Range Number filter instead. 39329
reports, scorecards, small multiples Reports, scorecards, and small multiple views do not support metric sets with data retrieval format set to Raw Data. These are metric sets created when you drag a database table directly onto the canvas. 41089
reports, scorecards, small multiples Reports, scorecards, and small multiple views do not support the Frame component. 39702
reports, scorecards, small multiples Zooming and scrolling (scrollbars) are not supported for charts appearing in a scorecard, report, or small multiple. 39215
reports When viewing reports directly within Dundas BI, if a single row expands to fill more than one page, its pages may display contiguously without separation from page margins, headers, or footers. This does not affect reports once exported to PDF. 77113
dashboards Drag-and-drop of files onto the dashboard canvas from outside the browser does not work in certain situations in Windows 8. 42075
dashboards Positioning items outside of the canvas and moving them in through script is not supported. Consider using layers or the hidden property instead.  
dashboards, data input When setting up a data input interaction, writing to a data input transform in an inherited data cube is not supported and will not be available as a selection. 62144
PDF export, image export A state indicator that displays an image may appear blurry when exported to a PDF or image file. This is due to a known issue with the Chrome browser relied on for all exports. Using a data image instead can avoid the problem. 61752
Excel export, OLAP Exporting to Excel with the measure format set to OLAP will not include the number formatting. 63034
Excel export, table When exporting columns using Group Text, the first grouped column's group header settings are applied in Excel. 73198
Excel export, table Table columns using a color rule with distribution set to Round Interval or Round Continuous are treated as Equal Interval and Continuous, respectively, when applied to the spreadsheet's cells when exporting to Excel. 79870

6. Data Visualizations

re-visualizing When re-visualizing a data visualization from one kind to another, only the underlying metric set is maintained and not any visualization-specific properties. This is because a table does not support chart-specific styles, for example. To get the original visualization and its styling back when viewing, reopen the file or use the Revert To Original re-visualize option. When editing, use undo in the toolbar, or first check in the file, use the Update button on the Data Analysis Panel, or save a style. 42018
table When the row header mode is changed to Single Indented Column in a table visualization, totals are required and will be enabled automatically on the metric set. 49787
