Columns Filter Details Report

After the node runs, the Columns Filter Details Report is generated in the Edit Column Details dialog box. Columns of the grid summarize the data quality information.

The default settings show both Attribute Importance and Data Quality.

• When Attribute Importance is selected, the following are displayed:

  • Rank

  • Importance

• When Data Quality is selected, the following columns are displayed:

  • % Null

  • % Unique

  • % Constant

The Hints column in the grid indicates the columns in the data set that do not pass data quality or do not meet the minimum importance value.

Bar graphs give a visual indication of values.

For example, if the percentage of Null values is larger than the value specified for % Nulls less than or equal, a hint is generated that indicates that the percentage of Null values is exceeded. If the percent of NULL values is very large for a column, you may want to exclude that column.
