This Bug exists in Koha Versions 23.11.05 and prior !

In the ERM module eUsage > Reports > Saved reports exists a ‘Display by year’ toggle at the top. If there is more than one year, you could use this to update the table with data from previous years.

Unfortunately this feature does not work, it displays always the same results.

to reproduce:

1.) harvest some usage data from a data provider with start date last year and end date this year
2.) save three different reports for this data provider
  2a.) report for last year  (by month with period total)
  2b.) report for this year  (by month with period total)
  2c.) report for both years (by month with period total)
3.) Check now in the reports you created in 2a.) and 2b.) that the monthly usage data for last year differ from usage data this year
4.) Go to the report you created in 2c.) and try to switch between the years by using the drop down and click on the button 'Update table'
5.) recognize that you see "Processing..." very short, but nothing happens
