Frequency Based Records

Question

Hi All
A little overview
we have a intake system where users submit requests and we process them . Some of our requests are recurring which means after we get the original request we create manual requests for that recurring request and process them until the original request expires
Lets assume all original requests are stored in Table A,Table B and Table C
Manual requests are going to be steored in Table D.
We have created a process to generate automatic requests in Table D based on original Request information from Tables A,B,C . I was using a cursor logic which was working fine for generating requests where the recurring frequency selected was Monthly and
Quaterly. I needed help in the query to generate records when the original requests came with frequency selected as Weekly or Bi weekly and got help from a differant thread where it was suggested to create a calendar table and then start using the calendar
table to generate records irrespective of the frequency and it worked with sample data.
Below is the Query
Declare @Sample Table(Requestid int, Receiveddate smalldatetime, frequency varchar(10), assignedanalystid int, requesttypeid int, CustomerName varchar(50), CompletedDate smalldatetime, ExpirationDate smalldatetime)
Insert @Sample(Requestid, Receiveddate, frequency, assignedanalystid, requesttypeid, CustomerName, CompletedDate, ExpirationDate)
Select 123456, '12/31/2013', 'Monthly', 123, 34, 'Testing Company', '1/15/2014', '12/31/2014'
Union All Select 123654, '12/31/2013', 'Weekly', 123, 34, 'Testing Company', '1/15/2014', '12/31/2014'
Union All Select 125000, '12/31/2013', 'Bi-Weekly', 123, 34, 'Testing Company', '1/15/2014', '12/31/2014';
Select s.Requestid + Row_Number() Over(Partition By s.Requestid Order By c.dt) As Requestid,
Cast(c.dt As smalldatetime) As ProductionMonth,
s.assignedanalystid As AssignedAnalyst,
s.frequency As freqcd,
Cast(c.dt As smalldatetime) As EnteredDate,
s.requesttypeid As rptdesc,
s.CustomerName As groupname,
s.Requestid As originalrequestid
From @Sample s
Inner Join dbo.Calendar c On c.dt Between s.CompletedDate And DateAdd(month, 1, s.ExpirationDate)
Where (s.frequency = 'Monthly' And c.D = 1)
Or (s.frequency = 'Weekly' And DateDiff(day, s.CompletedDate, c.dt) % 7 = 0 And c.dt > s.CompletedDate And c.dt <= DateAdd(week, 1, s.ExpirationDate))
Or (s.frequency = 'Bi-Weekly' And DateDiff(day, s.CompletedDate, c.dt) % 14 = 0 And c.dt > s.CompletedDate And c.dt <= DateAdd(week, 2, s.ExpirationDate))
Order By originalrequestid, Requestid;

How should i modify the above so that i use a requestid from Table A,Table B,Table C and generate its relevant requests in Table D

-- Cursor loop
Example:
So for example a request comes in Jan 2014 with frequency selected as monthly and the expiration date is Dec 2014. we
have to send the user monthly reports until Jan 2015 for which my monthly logic submits requests and one of our team member uses that automatic request generated by the query to process them monthly.
