When someone wishes to get a report for all Income made for a day, you should use the Manager's Report for the given day.
Notice the section at top called "Folio Charges / Income". This summarizes the groups of income and then provides a Total at the bottom. That is the daily total of income.
If further detail is needed on any Income category, then use the Transactions Report and select the drop-down menu "Transaction Category" and use the same date to get a detailed list of transactions for all folios that made up the 'Income' reported by the Manager's Report.
