QA levels have an "auto advance" feature. When enabled, all charts will skip that QA level and advance to the next available QA level. By applying filter rules, charts that meet the filter criteria will STOP at that QA level.
QA level filters are historically an "OR" statement; meaning if it meets ANY of the filters selected, the chart will stop at that QA level. The Filter Grouping will allow for custom searches so any combination of "AND" or "OR" will apply, and specific charts will stop.
The new feature for the grouping statement will allow for advance criteria grouping similar to Custom Report Grouping.
By default, the auto advance will follow the old, non-grouped method of advancing for that QA level. If a grouping statement is saved, it will adhere to the grouping statement.
If the grouping statement is blank, it will also follow the old method of advancing charts.
