When looking at the Deliveries table, there is no way to add information about the package contents or the delivery attachment. In my case, I would really like to list the number of items in the delivery and the file size for the ZIP attachment. This would make it easier for me to confirm the contents of the Delivery without visiting the details of the Delivery attachment individually.
I am always fearful about the contents of a Delivery's ZIP because Windchill is quite good at declaring victory by sending me an email only for me to find the Delivery ZIP only contains a portion of the items listed in the package. This is definitely true as the size of the package increases.
