Sql Query issue and error regarding groupby cause - sql

Question

I am trying to calculate the total number of Projects in every year. and also how many projects are active, how many of them are canceled.
I tried to group by cause for PRojects dates so we have a total number of project in every year but I am not sure where to start and what to do
Select ts.Id as projectid ,
--a.ParentObjectId,
ts.RequestName as ProjectDates,
ts.Type,
ts.Category,
ts.SubType,
ts.status as projectstatus,
Count (ts.ReceptionDate),
cast (ts.ReceptionDate as Date) as ReceptionDate,
from [rpt].[TransmissionServicesRpt] ts
left join [dbo].[AuditHistory] a on a.ParentObjectId = ts.Id
Left join [dbo].[User] u on a.CreatedById = u.id
Group by ts.id, ts.ReceptionDate
+ -------------+--------+-----------+------------+----------+-----------------+
| New Projects | Active | Cancelled | Terminated | Inactive | Carried Forward |
+ -------------+--------+-----------+------------+----------+-----------------+
| 2013 | 32 | 45 | 4 | 11 | 30 |
| 2014 | 45 | 75 | 17 | 14 | 44 |
| 2015 | 46 | 90 | 25 | 21 | 44 |
| 2016 | 30 | 74 | 27 | 10 | 37 |
| 2017 | 82 | 119 | 11 | 26 | 82 |
| 2018 | 86 | 168 | 29 | 24 | 115 |
| 2019 | 23 | 138 | 9 | 4 | 125 |

You want one result row per year. So group by year. You get it via YEAR or DATEPART. Then count conditionally:
select
year(receptiondate) as year,
count(*) as total,
count(case when status = 'Active' then 1 end) as active,
count(case when status = 'Cancelled' then 1 end) as cancelled,
count(case when status = 'Terminated' then 1 end) as terminated,
count(case when status = 'Inactive' then 1 end) as inactive,
count(case when status = 'Carried Forward' then 1 end) as carried_forward
from rpt.transmissionservicesrpt
group by year(receptiondate)
order by year(receptiondate);
