If you are looking for a report that will provide a list of orders for which a reship has been issued, the "Customer Service Activity" report can provide this information. The report can be filtered to show orders with items that have been re-shipped. Simply select "sys:Actions Reship" from the Activity drop down menu and run the report for your desired date range and report layout, and you will see orders with items that have been re-shipped.
Attached is a sample of what the report selections would look like.
