The table is more of a reference of the various SFIs, and not the order.
Please see section 1.1 of the Pax PDF for a diagram that describes the order. While similar, there are some small differences. For example, the you would provide the invoice header record, then the reference records, then a group of coupon records, then the source code total record, then a group of rejections, then the source code total. The table in the excel doesn't make it clear that the source code total comes at the end of a group of an individual source code.
Also note that the diagram shows a group of "Rejections", and a source code total record after this group. In reality, you might have 3 separate gorups of rejections, with separate source code total records (source codes 4,5,6).
A clarification will be added to the next release of the ISPG.
