Resolved Issues

The following is the issue addressed in this release.

Table 1: General resolved issues

Resolved Issue Issue ID

Cross-site scripting vulnerability: if the description of a report or report folder contains JavaScript script code enclosed in a <script> tag pair, then that code is executed on the client side when the page is rendered.



Known Issues

The following is a list of issues, including those attributed to third-party products, known to exist at the time of release.

Table 2: General known issues

Known Issue Issue ID

Automatic activation of Compatibility View for Internet Explorer works only on non-server Windows versions and only if the Knowledge Portal URL contains the NetBIOS server name. If Knowledge Portal is accessed through the IP address, FQDN or localhost, Compatibility View is not enabled.


For the Knowledge Portal to be installed properly, make sure Microsoft Data Transaction Coordinator is installed and running on the target computer.


The Knowledge Portal operation on Microsoft IIS 6.0 Web Farm is supported for single node NLB clusters only; for other configurations, wizards will not operate properly.


To install the Knowledge Portal on Microsoft Cluster Server cluster, Microsoft Data Transaction Coordinator is required.


If SSRS is running on a computer that belongs to a workgroup, and while client computer is located in the domain, then a user will fail to run Report Builder on a client computer (due to authentication error).

To prevent from problems when launching Report Builder remotly, configure access rights as described in the Installation Guide.


The following error may occur in Internet Explorer browser on the client side when trying to display the Reports, Data Sources, and Search tabs of the Knowledge Portal after navigation in reports tree, or after selecting a folder and clicking Remove Folder option:

'Unknown error. Error page description: Invalid_Viewstate. Client IP: <client_ip> Port: <port_number> User-Agent:<browser_client_configuration> ViewState: <view_state_description> Http-Referer:<link_to_invalid_URL> Path:'<path>.

To resolve the problem, click Refresh on the Internet Explorer toolbar.


When you try to apply several parameters to the reports using the Property Manager Wizard, and an error occurs during the application of one parameter, other parameters will not be applied either.


If you perform a Repair action when running the Report Pack installer from Add/Remove Programs, removed data sources are restored and assigned to the Report Pack reports but not models.

To assign these data sources to the corresponding models, use the Change Data Source Wizard.


For the Knowledge Portal to work correctly on a client computer, the site where the Knowledge Portal is installed must be added to the Trusted Sites list on that client computer, and the Allow META REFRESH option (Control Panel | Internet Options | Security | Custom Level | Miscellaneous | Allow META REFRESH) should be enabled.


Data-driven subscriptions cannot be copied from a source report using the Property Manager Wizard. Therefore, if there is at least one data-driven subscription among copied subscriptions, none of them will be copied.


For the Knowledge Portal to work properly, we recommend that to return to the previous page you use the Back button provided by the Knowledge Portal interface when it is displayed instead of the browser's Back button.


Date/time format used in SSRS and Knowledge Portal may differ (for example, M\D\YYYY and D\M\YYYY); if so, the following error message is displayed:

The value provided for the report parameter 'EndDate' is not valid for its type.

This may cause problems when you use Property Manager Wizard to apply a value to a Date/Time filter; besides, when running Report-Driven Data Import Wizard, user settings for date and time are not determined properly—reporting server local settings are displayed instead.

To avoid such problems, the following steps can be taken:

  1. On the computer where the Knowledge Portal runs, select Start | Settings | Control Panel | Regional and Language Options.
  2. On the Regional Options tab, click Customize.
  3. Click the Date tab and change the date format to match the one on SSRS.


When using the Property Manager Wizard to copy a value for query-based parameter (for example, a filter like Time Interval), the value will not be applied; no error message is issued, however.


When using the Property Manager Wizard to copy a value for query-based parameter (for example, a filter like Time Interval), the value will not be applied; no error message is issued, however.


If you use the Property Manager Wizard to apply security settings to a report by assigning SSRS role to user account which had access rights to this report only (but not the rights to access the Knowledge Portal folder in SSRS), these settings will be applied to the report. However, this user will be able to view the report via Internet Explorer only by specifying a direct hyperlink. No upper-level items (folders) will be available to this user. For information on rights and permissions required for work with the Knowledge Portal, refer to the Installation Guide.


When using the Property Manager Wizard to copy security settings from a source report to target report, consider that roles will be assigned to user accounts in the following way:

  • If an account was not previously granted access to target report, it will be assigned the necessary role and added to the corresponding list of accounts.
  • If an account had access rights to target report, and these rights differ from this account's rights on the source report, then source ones will take precedence (the role this account will have for target report is copied properly).
  • If an account was previously granted access rights to target report only (not for the source one), no changes will be made.


When you copy folders as you organize reports, source folder security settings are not set correctly (they are inherited from target folder's parent while original settings are removed).


To view a report created with Report Builder, user account should be granted the Manage Models right on the SSRS folder where the report (RDL file) was saved after creation.


Subscriptions to a source report or folder are not copied when you copy a report or folder.


If you delete a report model, then using Property Manager Wizard to assign a new model to the reports (based on the deleted one) will not fix the problem (though the wizard will quit without error). You can be assign another model to these reports using the SSRS Report Manager.


You may want to copy the report's data source properties using Property Management Wizard and selecting the Apply only to reports designed for the same products as the source report check box. If so, note that target reports (the ones these properties will be applied to) will be selected considering not the products explicitly specified for the reports (displayed in the report properties) but the products associated with the data sources of the reports.


Property Manager Wizard will not help in applying parameter values to report filtering parameters of List of check boxes type.


Report-Driven Data Import Wizard does not work properly if nlb clusters are used.


If you launch Report-Driven Data Import Wizard for any report from MIIS Report Pack, and select View the report after finishing check box on the final step of the wizard, the following error message is displayed after you click Finish:

Reporting Services Error:

An attempt was made to set a report parameter 'Computer_like' that is not defined in this report. (rsUnknownReportParameter)

To avoid this problem, clear View the report after finishing check box, and after completing the wizard, use View Report command from Options to display the report.


To view the Temporary Tables Clean-Up job status and date\time, take the following steps:

  1. On the SSRS Report Server, select the Home\QKP\SharedDataSources\Clean-up Reports folder.
  2. Select the report with the same name as the data source whose clean-up you are interested in.
  3. In this report Properties, click History. A list of snapshots will be displayed. If there are no items in the list, this means no clean-up was performed for the data source.


The DataSourceCleaner.exe utility can be used only if you use integrated Windows authentication when connecting to the database. If SQL Server authentication is specified in connection settings, you will not be able to use this utility.


When assigning the SQL Server 2005 database roles to accounts planned for database access, you must also specify the Default Schema with the same name as selected account. For that, provide the account name when configuring user mapping on the User Mapping page of the Login Properties (in Microsoft SQL Server Management Studio). You can enter the account names browsing for them; if they do not exist in the browsing list, they must be entered manually.


When you try to change or add a role for an account using the Property Manager Wizard, you may get the following error:

Error page description : Arithmetic operation resulted in an overflow.

As a workaround, perform this operation directly in the Reporting Services Web UI.


When you create a subscription and try to select the report output share in the Subscription Wizard, you may get the following error on Windows Server 2012:

Error page description : Arithmetic operation resulted in an overflow.

On Windows Server 2003 and 2008 no error occurs, but shares are not listed anyway.

As a workaround, type the share name directly in the Path text box on the Select Delivery Method step.


In environments where Knowledge Portal uses HTTPS to communicate with Reporting Services, if you keep Knowledge Portal open and idle for a long time in your web browser and then resume working with it, you get the following error message:

The underlying connection was closed. An unexpected error occurred on a receive.

If this happens, refresh the browser page.



Table 3: Microsoft SQL Server Reporting Services-related known issues

Known Issue Issue ID

Some reports appear to be wider than the page. The reason is that the width of the fields in such reports varies depending on the values in the fields.


Some subreports are cached. If you configure filters in the parent report, the subreport is not regenerated with these filters. Instead, the subreport's version is loaded from the cache. To compile a subreport with filters, press Ctrl+F5 to refresh the subreport page.


For very large reports, the Print Preview page may not open and the report may not print.


Page breaks in the online version of a report may not correspond to the page breaks in the printed version.


If large fonts are in use, the Report View page (if credentials to connect to the data source are prompted) is displayed incorrectly.


If the Microsoft SQL Server Reporting Services and Microsoft SQL Server used to generate a report are installed on different computers, then the report cannot be compiled using the Windows Authentication of the user currently logged on to the Knowledge Portal. Consider using SQL Server authentication.


Search in report descriptions can be performed only through the first 512 characters of the description.


If browsing for SSRS local user/group accounts when configuring report (folder) security settings, in case of remote installation (Knowledge Portal installed on a computer different from the one where SRS runs), similar account found on the Knowledge Portal computer will be selected.


If the password was changed for the user account you planned to use for browsing Active Directory (specified during the setup), then error will occur when you try to search for users when assigning security roles in the Knowledge Portal.


Japanese characters in the reports exported to PDF are not supported.


Custom reports based on the SSRS 2008 schema are not supported.

Table 4: Report known issues

Known Issue Issue ID

The Run Data Import action doesn't work for any reports in Quest Knowledge Portal 2.11. If you try to use the action, it fails with an error like the following: "Method not found: Void RDDIClientLib.RDDIClass.Connect”.

Solution: You can fix this issue using a replacement DLL file available from Quest Support. For details, see Quest Knowledge Base article 316800.


Report-driven data import for InTrust, InTrust for Active Directory and InTrust for File Access plug-ins reports will operate properly only if the list of computers (used by Computers filter) contains no wildcard characters; otherwise, corresponding report fields will contain no data.


If you open a report and try to customize report view using the Customize Report View option, then in case you clear View the report when customization is completed check box and close the dialog by clicking OK, changes will not be applied (no refresh will take place after you click Refresh, CTRL+Refresh, or View Report).
