You can easily change the existing filters you applied to a recurring report in Usage Analyst. Keep in mind, you can only edit a standard filter or a filter you create. You will not be able to edit or delete filters created and shared by others.
Click Reports, click Voice Reports, then click Usage Analyst.
Click the icon on the right side of the row for the account you want to view.
Control Center opens Bill Analyst in a new tab.
On the blue bar, click View: Bill Analyst, then click Usage Analyst.
Click the Setup tab.
In the Tools section, click Filters.
Select the radio button of the report you want to edit a filter for, then click Edit Filter.
From any of the two lists and one field, edit your filtering parameters. You can have up to 20 rows for each filter. The last row cannot be a group. Each group needs a condition. A filter cannot be saved if a group ends without a condition row. If a group contains no condition and ends, you'll get an error message.
