So I want to find out how many shipments ship how many different items. For example: I have a report that groups the data by shipment. i.e multiple items per shipment. Now what I want to do is group those on number of items to answer the question, "How many shipments shipped 4 items?"
Something like this:
5 Shipments with 2 items <--------------------- How do I get these groups?
Shipment # 123443 Number of items: 2 \
Shipment # 342312 Number of items: 2 \
Shipment # 218245 Number of items: 2 = These are already groups with a
Shipment # 342523 Number of items: 2 / count of items per shipment
Shipment # 345234 Number of items: 2 /
2 Shipments with 3 items
Shipment # 218154 Number of items: 3
Shipment # 1518451 Number of items: 3

You'll have to implement this on the DB side or via a SQL Command or SQL Expression in CR. For example, something like the following SQL Expression would work:
(select count(item)
from shipment
where shipmentID = "shipment"."shipmentID")
Then just group on this new expression which will give you the number of items per shipment for every row in your report.
