This step covers how to use the report_waivers Tcl command to generate a summary report for CDC, DRC, and methodology waivers.

Important: Before running the report_waivers command, you must rerun Report CDC, Report DRC, or Report Methodology to ensure that added or removed waivers are included in the statistics reported by report_waivers.

To rerun Report CDC, enter:
```
report_cdc
```
To rerun Report DRC, enter:
```
report_drc
```
Note: You do not need to rerun Report Methodology, because no methodology waivers were set.
To create a summary report, enter:
```
report_waivers
```
By default, report_waivers reports only waived violations. The following figure shows the UCIO-1, CDC-10, CDC-11, and CDC-14 rules that have defined waivers.

Note the number of waived objects and total violations:
- The aggregating DRCs are reported as 1 violation per object inside the violation. Because there are 113 objects in NSTD-1, 115 objects in UCIO-1, 1 in RTDAT-13, and 1 in AVAL-326, a total number of 240 DRC violations are reported in the summary table.
- The Report Summary table reports all of the violations.
- The Report Details tables only report the check IDs that have one or more waivers.
To generate detailed tables with all of the rules, including rules with no waivers, enter:
```
report_waivers -show_msgs_with_no_waivers
```
The following figure shows the report with all DRC and CDC rules reported in the Report Details.
To run Report Methodology, enter:
```
report_methodology
```
To generate detailed tables with all of the rules, including rules with no waivers, enter:
```
report_waivers -show_msgs_with_no_waivers
```
The exact statistics are reported, as shown in the following figure.

Note: This figure does not include the Report Details (CDC) section.
