SQL Pivot Result

Dear Experts,
I have a attached store procedure to display records as Pivot Table. this is showing perfect data only creating issue to convert PaidUnPaid Column into converting

if i replaced 'Paid' to -1 then its run perfectly
When i placed 'Paid' instead of numeric its not run

My SQL is as follows:
Drop Table #tempFeePaidUnPaidDetail

Select a.StudentId
  , b.GRNNo
  , b.ParentId
  , b.StudentName
  , c.FatherName
 , Class = e.ClassName  
  , Section = f.SectionName
  , Shift = g.ShiftName  
  , d.RollNo 
 
  , MonthNames= left(case when ftm.MonthNo is null then DateName( month , DateAdd( month , a.MonthNo, -1 )) else DateName( month , DateAdd( month , ftm.MonthNo, -1 )) end  ,3)
   , PaidUnPaid=Case When (a.Credit -Isnull((select Debit=SUM(debit) from FeeTransactionsMonth xx 
				Where xx.MonthNo=a.monthNo and xx.FiscalYearId=a.fiscalyearid and xx.TransId=a.TransId Group by TransID, MonthNo,FiscalYearId),0))=0 then
				'Paid' else CONVERT(Varchar(10),a.Credit) end
    --case when ftm.TransId is null then a.Credit 
	--				 When (a.Credit - isnull(ftm.Debit,0)) = 0  then '0'
	--				 Else (a.Credit - isnull(ftm.Debit,0)) end
	,MonthNo = case when ftm.MonthNo is null then convert(varchar,a.MonthNo) else convert(varchar,ftm.MonthNo) end
Into #tempFeePaidUnPaidDetail
from FeeTransactions a
Join Students b on a.StudentId =b.StudentId 
Left Outer Join Parents c on b.ParentId =c.ParentID 
Left Outer Join StudentYearRecord d on a.StudentId =d.StudentId and a.CampusId=d.CampusID and a.FiscalYearId=d.YearID
Join Classes e  on d.PC=e.ClassId 
Join Sections f on d.Section=f.SectionId 
join Shifts g on d.Shift=g.ShiftId 
left join FeeTransactionsMonth ftm on (ftm.TransId = a.TransId)
Where a.Credit >0 
and a.FiscalYearID=1
and (b.PresentClassId like 1)
--and (b.PresentSectionId like @SectionId)
--and (b.PresentShiftId like @ShiftId)
--and (b.GRNNo like @GRNNo)
and b.FeeTerm not in (2)
Order by e.ClassName  
  , f.SectionName 
  , g.ShiftName, d.RollNo

It is as I suspected.  It will not work that way.  If you only expect one value, you could try MAX as the aggregate.  If you need the SUM, then leave paid as zero, so SUM will be zero.  That way you can use COALESCE(CONVERT(VARCHAR(10), NULLIF(pivot_column, 0)), 'Paid') on each of the pivoted columns.

Kevin CrossChief Technology OfficerCommented:
I may not be following the logic completely, but it appears you are passing to your procedure the first query and asking it to SUM(PaidUnPaid) column.  Therefore, if you make it 'Paid' in the first query, it should not work.  Try making this column just the difference in debts and credits as a number value, then in the final select use CASE statement (or ISNULL-NULLIF combination) to replace 0 with 'Paid'.

I have tried to do something like this but no luck

Exec CrossTabMake 'Select StudentId,GRNNo,ParentId,StudentName,FatherName,Class,Section,Shift,RollNo,MonthNames,MonthNo,
					PaidUnPaid=Case When PaidUnPaid>0 then PaidUnPaid else ''-0'' end From #tempFeePaidUnPaidDetail'
,'MonthNo+MonthNames'
,'Sum(PaidUnPaid)[]'
,'StudentId,GRNNo,ParentId,StudentName,FatherName,Class,Section,Shift,RollNo'
,''
,'Class,Section,Shift,RollNo'

What is the error message it is giving you?  To debug, you can PRINT out the dynamic SQL you are creating.  You may spot the issue more easily that way.
