Dundas BI - Product Notes
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 product limitations.
2. General / Application
|logon, Safari||When accessing Dundas BI using Safari browser and Private Browsing mode, the login fields will not be visible.||N/A|
|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|
|logon, Windows Authentication||Regarding Windows Login/Authentication, note that Dundas BI does not support domains from separate forests for the purposes of logging on. In other words, the Dundas BI application pool user and any Windows accounts used to log on to Dundas BI must be from domains in the same forest.||51121|
|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, resulting in various UI issues.||N/A|
|user interface, Internet Explorer||
Due to inherent limitations with Internet Explorer, it may experience reduced performance when compared to other browsers.
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.
3. 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||
Some ODBC drivers are only available in 32-bit versions. To use 32-bit drivers on a 64-bit server, you need to run IIS or your application pool in 32-bit mode.
Discovery of table and view definitions may not work for some ODBC 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 data sources.
Stored procedures and functions are not discovered.
|data cubes, calculated element transform||The CFlat switch statement is not supported.||59512|
|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|
|warehouse storage||The floating point values NaN and Infinity are not supported and will cause the data warehouse build to fail.||53933|
|hierarchies, in-memory storage||Previewing a hierarchy in the Hierarchy Designer 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, OLAP||Metric set automatic count measures are not supported for OLAP.||41266|
|metric sets, dynamic hierarchies, period over period||Period over period (pop) cannot be used with a dynamic hierarchy.||50824|
|metric sets, period over period||Period over period (pop) cannot be added to an existing pop measure.||50927|
|metric sets||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|
|expand and collapse members||The expand and collapse members functionality is not supported in formula visualizations/formula metric sets.||49485|
|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|
|metric sets, data annotations||Preventing Data Annotations by unchecking Allow Data Corrections is not supported on OLAP-based measures.||51130|
|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 connectors, Excel||Mixed data types, such as an apostrophe prefix to a date value, prevents both Excel and Dundas BI from recognizing the desired data format.||59225|
|Excel export, OLAP||Exporting to Excel with the measure format set to OLAP will not include the number formatting.||63034|
|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|
4. Dashboards / Reports / Scorecards
|filtering||Changes made in the Filter Visualizations dialog may not be saved after closing Internet Explorer.||39288|
|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||Reports and scorecards 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||Reports and scorecards do not support the Frame component.||39702|
|reports, scorecards||Zooming and scrolling (scrollbars) is not supported for charts appearing in a scorecard or report.||39215|
|dashboard designer||Drag-and-drop files onto the dashboard canvas does not work in certain situations in Windows 8.||42075|
|dashboard designer, drop down list||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.||50600|
|dashboard designer, editing label text||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.||51116|
|dashboards||When viewing the dashboard in Re-size mode, scrollbars may randomly appear in Google Chrome. This is a known issue with the Google Chrome browser and is being investigated by the Chromium team. To remove the scroll bars, resize the dashboard.||57933|
|dashboard designer, editing image source||When selecting or editing an image Source property containing a very long string, Google Chrome may freeze. This is a known issue with the Google Chrome browser and is being investigated by the Chromium team. To avoid the situation, upload the image into Dundas BI.||60230|
|dashboard designer, interactions||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|
5. 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 not a limitation per se but it means that if you go to apply certain styling to a chart, re-visualize it as a table, and then re-visualize back to the same kind of chart, you may lose some of the original styling. This is because a table does not support chart-specific styles. To get back your original styling you can use general strategies such as checking things in before re-visualizing (so that you can undo checkout later, or roll back versions), using the Update button the Data Binding Panel to update the metric set's default visualization, or saving visualization properties as a style.||42018|
|table||When the row header mode is changed to Single Indented Column in a table visualization, totals will be enabled automatically. You can see this if you open the Data Binding Panel, click Edit, and then look for the Shown Totals field.||49787|
|table||When using the properties Freeze Total Rows and Show Totals At Bottom together in a table visualization, the subtotal row has to be loaded to display in the freeze row. If the subtotal row is too far down the table, data for it will not be retrieved and the freeze row will not be displayed.||57648|
