One common report that you may want to change is the Bill Shipped Orders process. This process is actually both a process and a report. This report/process is responsible for creating invoices from packing slips. If you would like to add information to the orders file and have this information carried over to the invoice file, you may change the Bill Shipped Orders process to copy the information.
Before you make any changes to the Bill Shipped Orders process, study it carefully to make sure you understand what is being done. This report/process must re-do a lot of work that was done by the order entry screen to allow for partial shipments. Unless you know what you are doing, it is best to leave these parts alone.
The report/process is divided into sections much like the invoice screen itself. To add fields to the invoice, insert extra assignment statements at the appropriate places to copy the information.
