How to clean up historical data

Open System Management > Data Maintenance on the client.

Select the historical data you want to clean, such as historical bills, then select “Historical bill cleaning”, select the start time and end time of the filter, and then click Filter.

Note: If the start time and end time are not checked, it means to filter all historical bills.

Check the date you want to clear the bill, then click Delete, and finally apply it.
