Problem to identify values in a case statement.

Question

Hi Friends,
Total number of records in my report should be divided by 5 and to be alloted into 5 grades in Grade column.
This is what I have done so far in my report with following layout.
S.No - Col A - Col B - Col C - Grade ( Colums A,B,C will be hidden in Report)
*****Column C will have only 5 values at max ( 0.0, 0.2, 0.4, 0.6, 0.8).The below example is for 6 records in a report.The same will be applied for 7,8,9,10 records.
In column A: MAX(cast(RCOUNT(1) AS DOUBLE))/5 ( Ex : 6/5 = 1.2)
In Column B: Truncate(MAX(cast (RCOUNT(1) as double)/5), 0) ( Ex : 6/5 = 1.0)
In Column C: Col A- Col B ( EX:1.2 - 1.0 =0.2)
(MAX(cast(RCOUNT(1) AS DOUBLE))/5 - Truncate(MAX(cast (RCOUNT(1) as double)/5), 0))
Now In Grade coulum I want to use this column C to Grade the records with case statements in it.
I am trying to use the following case statement for Grade Coulmn
Case
when (MAX(cast(RCOUNT(1) AS DOUBLE))/5 - Truncate(MAX(cast (RCOUNT(1) as double)/5), 0)) = 0.0 then .........
when (MAX(cast(RCOUNT(1) AS DOUBLE))/5 - Truncate(MAX(cast (RCOUNT(1) as double)/5), 0)) = 0.2 then .............
when (MAX(cast(RCOUNT(1) AS DOUBLE))/5 - Truncate(MAX(cast (RCOUNT(1) as double)/5), 0)) = 0.4 then .............
when (MAX(cast(RCOUNT(1) AS DOUBLE))/5 - Truncate(MAX(cast (RCOUNT(1) as double)/5), 0)) = 0.6 then ........
when (MAX(cast(RCOUNT(1) AS DOUBLE))/5 - Truncate(MAX(cast (RCOUNT(1) as double)/5), 0)) = 0.8 then .....
end
Case statement works gud for 0.0 but not for other 4 values.
It is unable to identify other 4values.
Please tell me, how can I make case statement work for all values in above scenario.
Thanks in Advance,
Varsha.

In column A: MAX(cast(RCOUNT(1) AS DOUBLE))/5 ( Ex : 6/5 = 1.2)
In Column B: Truncate(MAX(cast (RCOUNT(1) as double)/5), 0) ( Ex : 6/5 = 1.0)
In Column C: Col A- Col B ( EX:1.2 - 1.0 =0.2)
(MAX(cast(RCOUNT(1) AS DOUBLE))/5 - Truncate(MAX(cast (RCOUNT(1) as double)/5), 0))Change the formula a bit by adding the by dim value for the MAX column.
Column A: MAX(cast(RCOUNT(1) AS DOUBLE) by DimTable.Column)/5
Column B: Truncate(MAX(cast (RCOUNT(1) as double) by DimTable.Column)/5, 0)
Column C: MAX(cast(RCOUNT(1) AS DOUBLE) by DimTable.Column)/5 - Truncate(MAX(cast (RCOUNT(1) as double) by DimTable.Column)/5, 0)
now write a case statement on top column c, based on your logic every 5th record will have a value 0.0
Note: Dimtable.column is the table.column for which the row count is taken.
Thanks,
