I have not checked in main, but in 24.11 when you harvest a datasource this kind of message is displayed : "Job for report type DR has been queued. Check job progress." It could be more informative : adding the name of the source and the begin and end date could make it easier to identify a job if you want to get more information
I see those informations will be added in the widget on the ERM home page https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=39320 But they could be added too in erm/eusage/usage_data_providers page
