Why does the dashboard show fewer records in the noncomplying record sample than on the graph?
This happens because the drill-through tables contain only a sample of invalid records. The number of saved drill-through records can be configured in the model project.
To do that open the DQD Project and double-click Preferences.
In the Output Record Sets tab, enter a limit for records display to the Noncomplying Record Sample Size field. Recommended sample size is 100. Maximum allowed size is 1000 records.
