A number of parameters are common across a number of reports and are described here.
Period
These parameters determine the period the report applies to. A start and an end day may be chosen using date pickers - both are inclusive. Handy links are available to set the period to the last day, week, month and year all including today.
Format
By default the report is generated as a PDF. You may use this parameter though to change the format to HTML if you wish.
