Issue When configuring reports there is no option to select the report to be exported once a month. Product Line EcoStruxure Security Expert Environment Security Expert Cause There isn't an option to have a  report run only once a month. Resolution A workaround for this would be to select a single day of the week for it to run.

Under File Export tab select the Enable File Export checkbox. Set the Time field to the time of day you want to run your report. Set the Export Directory to the folder you want to save your report export files to. Under Days to Export select one day of the week. Under Period select Last Month.

Once a month the Operator would then select the file in the report folder which will have the last months events in it. The filename of the report is "EventReport" followed by that Event Reports Database ID number.
