ReportScheduler now supports schedule of SLA reports for last day period for example, for any time of the day. Previously, one could only schedule SLA reports for last day within one minute past the end of period. For example, 12:01 - otherwise, the report would be generated for the now new period which is like one minute worth of report.
ReportScheduler 6.2.1_HF2 provides the hotfix.
You can obtain the hotfix from Nimsoft Support.
