For those that are trying to replicate the above it is important to understand this ONLY WORKS for "Products and Services" that are set up as "Inventory" for all products and services that are set up as "Non-Inventory" THIS WILL NOT WORK.

ps As mentioned below, I too agree that it is absolutely crazy that SKU's do not appear on the packing slip by default. The fact that you still have to "work around" this shortcoming almost 3 years after this issue was flagged is reason enough to move to a competitor like Xero.
