Compatibility of QKB and SAS Data Management Studio Releases

When a QKB is released, it might contain definitions that require a newer version of SAS Data Management Studio. Accordingly, to check for compatibility, review the System Requirements for your QKB to see what version of SAS Data Management Studio it requires.

Data Quality Warning for Incompatible Version

If you reference a QKB definition in SAS Data Management Studio, and the version of the QKB definition is incompatible with the version of SAS Data Management Studio that you are using, you will get an error, such as:

Failure loading the Locale ENUSA with error(s): |[117] Data Quality - Warning: 'Match' definition 'Name (Probabilistic)' has an incompatible version '9.1'. This definition may be unavailable at run-time."

To check for compatibility, review the System Requirements for your QKB to see what version of SAS Data Management Studio it requires.

Updating QKBs That Are Referenced in a Job That is Being Edited

As described in Previewing, Running, and Reviewing a Data Job, you can use the Preview tab to see the output of a given node in the job flow. If one of the nodes in the job references a QKB, then the output for that node in the Preview tab will reflect any QKB processing that is specified for the node. While you are editing a job, it is possible for you or someone else to use the customize features in SAS Data Management Studio to edit the QKB that is referenced by a node. The impact of doing this will vary, depending on whether you or someone else edits the referenced QKB.

Suppose that you want to edit the QKB that is referenced by the selected node in the Preview tab. You could do that in the same instance of SAS Data Management Studio. After modifying and saving the QKB, if you return to the job, the Preview tab for the selected node will not be automatically updated to reflect the changes made to the QKB. You could select a different node in the job, then re-select the node that references the QKB in order for the Preview results to be updated and reflect the changes made to the QKB.

It is possible, but not recommended, for someone to use a separate instance of SAS Data Management Studio to edit and save a QKB that is referenced by the selected node in the Preview tab. If this situation does arise, the person who is editing the job must select Tools > Reload Active QKB to see the effects of modifications to the referenced QKB.
