When you create a filter as follows, SAS^® OpRisk VaR overwrites filter criteria:

1. On the Criteria tab, deselect all values for a dimension.
2. View the updated counts on the Loss Data tab. See SAS Note 50191 for additional details about viewing updated counts on the Loss Data tab.
3. Save the filter ► close the filter ► re-open the filter.
4. Click the Criteria tab ► choose the dimension for which you had deselected all values.

This behavior is by design. Deselecting all filter options creates a filter that excludes all losses. This is a not a typical filtering scenario for analyzing loss data. Also, it can significantly degrade the performance of the filter. To provide a more meaningful filter result, SAS OpRisk VaR automatically reselects all filter criteria for dimensions that contain no selections when you save, close, and re-open the filter. The counts are updated accordingly.

If you need to produce a "no-loss" filter, you can create one that does not degrade performance by adding criteria such as General Ledger GL Code with a non-existent value.
