Say a client wants to add lot # to shipment report (SO64200 is the report name).  Therefore, you add the table SOShipLineSplit table to the report, add additional detail band and display lot #.  The report will look like the following example:  Batch# (lot#)

But say the client doesn’t like the layout it currently producing of the batch #.  It’s wasting space for the same items with the same information.  Example TESTPROD02, it’s repeating 3 of the same lines in Line #1 and #2.  To enhance the above report, you would need to modify the report and replace the detail bands with group bands.  The final will display the report as below as 4 lines instead of 6 lines as above.
