Return 0 count when a Department within a CTE contains records for one set, but not another

Question

This is a bit of a complicated question to explain, but I am hoping not as complicated to resolve. I will try to describe this generically to allow anybody who can provide a solution to provide a generic example that anybody could adapt to their data.
In my query, I created a CTE which combines two separate sets of data. One set of data lists who is within a given audience (call it audiencelist). The other set lists people who are in that same audience and have completed a given course (call if courselist).
This is then all brought into one table by the CTE.
My resulting report in Visual Studio 2008 is then going to include an expression to count each employee from both lists by department within the same field. (I will achieve this by first grouping by department, and then by the appropriate measure,
which in the case of this example, I am calling audiencelist and courselist. Then, I will include an expression that counts the Employees.) The problem is, if a department has somebody in the audience, but NOBODY from that department has completed the
course yet, I need the department to still show up in the "courselist" but with a count of 0.
Example of the desired result:
Dept 
Field            
Count
A       Audiencelist  25
A       Courselist     15
B       Audiencelist  20
B       Courselist     10
C       Audiencelist  20
C       Courselist     0
I was trying as best I can to make this a generic example, but let me know if it would be easier if I share some of my actual code so you can provide a solution. My hope was that somebody could offer a generic example I could adapt to my data.

Answer 1

I am having a little trouble following this example, or the one provided at the link above. I was hoping to just allow for a generic example, but I guess it may help if I share my actual code. My query is rather long, but I will just share the relevant parts
for the sake of the sample.

The final main query actually just pulls in everything from this CTE. My next step was going to be to pull this information all into the report, sort and group by MeasurePC (the Department, referred to in my company as a "Profit Center" and by
the MeasureID (GM101Cert for those who completed the course, GM101Avail for those who are part of the audience) and then have an Expression that would count each MeasureEmpFK (the employee codes). However, that is when I realized it wouldn't count 0's for
any MeasurePC in the GM101Cert set of data that did not have any people complete the course.
Here is a mock-up of how the data would currently look from this above query:

From here, I was going to pull the data into a report to count. Using the above example, my desired result would be:
Country   Code
SOURCESYSTEMID
Fiscal Year
Fiscal Month Nbr
Org Value
CURRENCYCODE
MEASUREID
MEASUREDOLLARS

I had planned to achieve this just by pulling the data into my report and then, instead of pulling the EmpFK, I would create an expression to count them. However, I realized this wouldn't achieve the 0 counts when some PC's did not have anybody who had completed
the course yet.
