When you use a Clustering node in SAS Data Management Studio, null values are not being properly counted.

For example, you might encounter the problem if you perform steps similar to the following:

• Go to the Clustering node.
• Select More Options ► Condition Matched field prefix ► Return a count of the number of times the condition was matched across the cluster.

The results show that the clustering is working correctly, but the count of the condition field when null values are present is not correct. The count should show 0.
