Hierarchy Details not how showing

Question

I am stepping through a project and the hierarchy has 3 levels, e.g. hierarchy name is Sales Rep ID, then level right under that is East, West,… level 3 is Atlanta, Chicago, etc…(cities), and next  level is Names of Sales Reps such as Kevin, Mike, etc  in the various cites.
When the query is generated, I get the highest level i.e. Sales Rep ID, is displayed and shows three key figures and values.
When I drill down on Sales Rep ID I don’t see the details of the hierarchy such as East, West, Atlanta, Kevin, Mike, etc. but I do see their corresponding values.
Sales Rep ID--Price-Quantity--
Revenue
Not Assigned Sales Rep ID (s)--10343237--
13050
$ 4.00     -
2 CSE----
$ 4.00
$ 14.00--10 CSE--
$ 38.00
$ 10.00--8 CSE--
     $ 40.00
$ 500.00-----36 EA--
$ 3,100.00
Any guidance? I realize from an example that “Expand to Level = 3” was not set so I modified the properties of the hierarchy and set it to 3; saved and rerun the query but the there was no change in the output of my query.
You assistance will be appreciated.

Hi Expert,
I suspect I have not made my point clear, this is very similar to an example in the Fufu Chapter 4, they did not have to insert each of the values of IO_SREP Hierarchy as you pointed out:
Expected Query output:
Sales Rep ID..........................Price....Quantity....Rev
=======================================
Overall result..........................617.........*.........3620
IO_SREP Hierarchy..………..500..........*.........3500
East
Atlanta
New York
MidWest
Chicago
Kevin
Chris
Mark
Where Kevin is ID01, Chris is ID02, Mark is ID02, etc.
In chapters 1-3, Sales Office, Sales Region and Sales Rep ID were created as InfoObjects. Then the master data were maintained for these infoobjects 
In generating the query result above the author did not have to insert ID021, ID02, etc
into the IO_SREP heirarchy.
In fact, if it was to be done as you suggested then that means if there are 5000 sales
reps this would be a very tedious exercise.
I still need help on this problem because in my situation, it shows the three key figure columns with all their values, except it does not show the column of regions, cities and sales reps, rather, it shows something like this:
Sales Rep ID--Price-Quantity--
Revenue
Not Assigned Sales Rep ID (s)--10343237--
13050
$ 4.00     -

$ 4.00
$ 14.00--10 CSE--
$ 38.00
$ 10.00--8 CSE--
     $ 40.00
$ 500.00-----36 EA--
$ 3,100.00
Thanks in advance.
