Sales Transaction Summary Report
STS Report shows more simplified and generalized information on your sales than Sale Transaction Details report. Its main columns are Transaction ID, Ext cost, price, and GP. All of them give you total numbers on the lower panel of report window.
See attached image.
However, you can easily access transaction details breakdown for each transaction id. Please note that every transaction ID in trans ID column is highlighted with blue - it means it contains a link to it. If you click one, it will show you details of each line (item) processed in that sale.
