Once you are done developing, you export the DQS KB and then create a new DQS KB by importing and publishing the KB to another server. Or, you might have deleted and recreated the KB with the same name. When you open the DQS Cleansing Transformation Editor, although the KB name is the same, you find that the reference to your DQS KB is gone and you get a warning message “The data quality Knowledge Base property is empty. Specify a valid Knowledge Base”. Naturally, you don’t want to remap the KB and recreate all mappings as this a tedious process involving many steps with many columns.

Solution: I’m not sure what design pattern was followed here, by SSIS identifies the KB by its identifier instead of by name. To fix the issue without remapping, you need to find the new KB ID and update the package source by following these steps:

  1. On the target SQL Server that is integrated with DQS, connect to the DQS_MAIN database and issue the following query by replacing the token with the name of your KB:
    SELECT * FROM [DQS_MAIN].[dbo].[A_KNOWLEDGEBASE] WHERE NAME = ‘<YOUR KB NAME>’
  2. In the query results, locate the ID column and copy the identifier.
  3. In SSDT, right-click on the package and then click View Code to open the package XML source.
  4. Find the knowledgebaseName property and overwrite the new identifier.

<property dataType=“System.Int64” name=“KnowledgebaseName” typeConverter=“NOTBROWSABLE”>1020033</property>

  1. Save the source and open the package in the designer.

Note that to resolve the KB identifier successfully, not only you need to import the KB on the target server but also publish the KB.

082913_2223_DQSErroraft1

DqsInstaller.exe can be found by default in the C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Binn folder. However, running the dqsinstaller-upgrade didn’t fix the issue. To fix it, I had to recompile the .NET assemblies by running dqsinstaller-UpgradeDlls. BTW, CU4 is still marked as in research by the DQS team and CU5 is not even on the list.
