I suspect there is a misunderstanding in what I'm trying to do.

The time frame of the existing "Sales Report" is just fine. I simply want to replicate it on a custom report. There are other things about that report that we do not like, hence the reason for the custom report.

Using a date range on the custom report is insufficient. Sometimes our month-end goes over by a couple days and I need the date range to mimic the range of the invoices on the current month. A static date range will pick up invoices from different months.

On my custom report, I am indeed using the "OE Orders and Invoices Header and Detail" but it shows data for the current year, not the current month. There is one table I have found that shows on the current month. It's called "Sales Report Summary", but none of the fields are indexed so I cannot use it in Crystal Reports.
