Unable to create a drill through or drill down report

Question

 
Hello I am new to report builder (or any SQL related tools) and I am still learning to do a many things.
Background: I have managed to design a pie-chart report that shows Number of Assets, and when they were maintained. The fields I have for the table seven columns
Asset ID (e. 123456), Accepted On Date(dd/mm/yyyy), Last Serviced on Date(dd/mm/yyyy),  Min. Service interval per year (e.g 1,2,3,4) Overall Risk Score (between 0-16), Risk Category (e.g Green or Orange), maintenance
Compliance (e.g Compliant or No Proof)
I get an extract in .rdl format from our Asset Database (CRM) which includes Asset ID, Accepted On Dates, Last Serviced on Date, Min Service Interval per year, Overall Risk Score
I add calculated field of Risk Category as Orange or Green, where an overall risk score > 8 will make the Asset ID fall in the Orange Category and any risk < 8 will be Green Category
The second calculated field is the Maintenance Compliance, where I have added formula when certain conditions between Accepted On Date(dd/mm/yyyy), Last Serviced on Date(dd/mm/yyyy) and Min. Service interval per year, are
met. When they are met, it is "Compliant", when not met it is "No Proof".
The pie chart has
Values as Count(Risk Category)
category Groups (Risk category) + (Maintenance Compliance)
Probelm: I am trying to design a drill down or a drill through report where if I click on the slice, the table displayed below will only contain values (or rows) corresponding to that region. So, if I click on Green - Compliant,
then a table should appear which shows only asset values which have Risk category value Green and Maintenance Compliance Value as Compliant
Please let me know if anyone can help     (Link Copy Paste in browser: https://drive.google.com/file/d/0BzjF_kUloVtkSUk0YlZDbFVYR3c/edit?usp=sharing)
Note: I am doing this report offline, as the server connection does not work. So i usually edit the .rdl file and then upload it to the server to check if it runs

Hello Alisa
Thank you for the response. I tried doing the following, and I am pretty sure I must be doing something wrong because of my inexperience with SQL tools.
But I get an error while I try to upload it onto the server. I have uploaded my files here
https://drive.google.com/folderview?id=0BzjF_kUloVtkSjhCd3J6VU11alk&usp=sharing
Is it possible to check these. The files are (.rdl file, error log text file, screen shot of error when uploading to server)
Also, in your explanation you mentioned
Add a dataset (DataSet1) in the report with the corresponding fields (when I try to add another data set(DS1) with the values shown in DSMain (my main report), it does not allow populate the query fields of the main report (DSMain). So I have to manually
add all query field + the two calculated fields (Risk_Category & Maintenance_Compliance). Add another dataset (DataSet2) with RiskCategory, MaintenanceCompliance two fields (I added another Dataset and named it as DS2, and copied the same Calculated
fields from DSMain (main report) for Risk_Category & Maintenance_Compliance
Add two parameters (RiskCategory, MaintenanceCompliance) in the report, get these Available value from DataSet2 fields.( two parameters appears new
RiskCategory --> Dataset-DS2, Value Field- Risk_Category, Label Field: Risk_Category
MaintenanceCompliance --> Dataset-DS2, Value Field- Maintenance_Compliance, Label Field: Maintenance_Compliance
3. Add two filters of DataSet1. Please refer to the following values:
Expression: [RiskCategory]
Operator: =
Value: [@RiskCategory](I am not sure I have clearly understood this part. As my values in Dataset 1 (DS1) are the same as the main report (DSMain), the query + calculated fields are the same. Hence my Dataset 1 (DS1) will also have a Calculated field
as Risk_Category and Maintenance_Compliance. And do I have to add these values as filters in DataSet2 (DS2) ? In which am actually manually typing Expression: [RiskCategory]
Operator: = 
Value: [@RiskCategory] 
Expression: [MaintenanceCompliance] 
Operator: = 
Value: [@MaintenanceCompliance]
Main Report
3. Add the subreport below “Specify a report”. (I had to give a random name as 'DrillThrough' in this field. Am I doing something wrong)
4. Click Add icon to add parameter to run the subreport. Please refer to the following values:
Name: RiskCategory (Note: This is parameter name in the subreport.)      Value: RiskCategory
Name: MaintenanceCompliance         Valeu: MaintenanceCompliance
(I had to manually type the Name & Value fields, as they did not appear in the drop down list when I click on add)
I am sure by now you must have realised how amateur I am with this tool
Please let me know
Thank you once again for being patient
