Adding Subject Areas - error

Summary

Using the 'Create Analysis' option and selecting 2 Subject Areas

Content

Hello,

I am new to reporting and trying to use some of the out of the box features.  The steps I followed are:

1. New > Report from the ribbon.   
2. 'Use Subject Area' [Work Management - Documents of Record Real Time]  
3. 'Guide Me' option and chose my page layout [Chart and table]
4. Chose Chart Labels [Document Type and Document Count]
5. Chose additional Table contents [Created By, Date From, Date To, Person Number]

This all worked fine and output was fine.

However, I would like to be able to identify which departments the results belong to.  Within DOR subject area, there is Manager Department but not the department belonging to the worker.  As Manager Dept can differ from the department the employee is in, this is not suitable.
