Webi sub query with aggregates

Hi,

I have a webi report requirement with 10 feilds,i have pulled all the 8 feilds in the report.I got struck with 2 fields  with MAX and Count (aggregate) .

we are planning to execute them with select clause by sub query option.

We are planning to keep  ID present in all the sub queires because i want them to be jonied by  ID.

1. Last Date of LSRF:

SELECT ID, Max(dbo.MetricRequest.RequestDate) FROM dbo.MetricRequest Where dbo.MetricStatusTypeKey In (‘1’,’2’,’5’,’6’,’7’,’8’,’9’,’10’,’11’,’12’).

2.   Number of Requests

SELECT  ID , Count(dbo.MetricRequest.MetricRequestID) FROM dbo.MetricRequest Where dbo.MetricStatusTypeKey In (‘1’,’2’,’5’,’6’,’7’,’8’,’9’,’10’,’11’,’12’

Any idea how to create sub queries in webi for aggregate calculations.

Thanks
