SSRS report arranging rows to columns - reporting-services

Question

I need to generate this kind of (please see the image) report in SSRS, and I wrote below 2 SQL's
Active Appointments created by Online and Call center
Cancelled Appointments by Online and Call center
with cte as
(
select
ATS.[Description] as AppointmentSource, AST.AppointmentStatusName,
Month(A.Appointmentdate) as MonthNumber,
Count(A.AppointmentID) as NumberOfAppointments
from
Appointment A
inner join AppointmentStatus AST ON AST.AppointmentStatusID = A.AppointmentStatusID
inner join AppointmentSource ATS ON ATS.AppointmentSourceID = A.AppointmentSourceID
where A.AppointmentDate between '01/01/2020' and '12/31/2020'
AND ATS.AppointmentSourceID in (1,3)
AND A.AppointmentStatusID = 1 -- Active
Group by Month(A.AppointmentDate), ATS.[Description], AST.AppointmentStatusName
UNION
select
ATS.[Description] as AppointmentSource, AST.AppointmentStatusName, Month(A.Appointmentdate) as MonthNumber,
Count(A.AppointmentID) as NumberOfAppointments
from
Appointment A
inner join AppointmentStatus AST ON AST.AppointmentStatusID = A.AppointmentStatusID
inner join AppointmentSource ATS ON ATS.AppointmentSourceID = A.AppointmentSourceID
where A.AppointmentDate between '01/01/2020' and '12/31/2020'
AND ATS.AppointmentSourceID in (1,3)
AND A.AppointmentStatusID = 2 -- Cancelled
Group by Month(A.AppointmentDate), ATS.[Description], AST.AppointmentStatusName
)
select AppointmentSource, MonthNumber, NumberOfAppointments, AppointmentStatusName
from cte
order by AppointmentSource, AppointmentStatusName asc, MonthNumber
How to arrange the results by Month in the SSRS report ?
Is there a better way to write the SQL and arrange in SSRS report?

Answer 1

Ignoring the actual SQL for now (it would be better to show the results of this rather than the t-sql)...
I think you have enough to build the report, with the exception of the Year which you don't appear to be returning. Once you have corrected this...
Create a new report and create your dataset as normal
Add a Matrix (not a table) to your report.
Add 2 Row Groups first goruped by Year and the second (child group) grouped by AppointmentSource
Add a column group, grouped by MonthNumber
Choose NumberOfAppointments as the value
That's it, you should get the results as above more or less.
