Generating Percent problem with divide by zero

Im trying to generate a percentage value on a agregated field
but in some groups there isn't any information so it tries to divide by zero
and i get an error
So i thought id use a IIf to se if either the Value or the Total was zero
and write out 0 % but the IIf seems to be running the calculation anyway..
heres the code that i'm using as an expression for the percentage field
=IIf(Sum(Fields!MyValue.Value) = 0 Or Sum(Fields!MyTotal.Value) = 0,
0,
SUM(Fields!MyValue.Value) / SUM(Fields!MyTotal.Value)
)
Is this a bug, or is their another way to se that reporting services doesn't
divide by zero?
// LeonHi Leon,
Welcome to use MSDN Managed Newsgroup!
From your descriptions, I understood you would like to know how to aviod
"divide by zero" error by using IIF. If I have misunderstood your concern,
please feel free to point it out.
Based on my knowledge, IIF is a function call and will therefore evaluate
all arguments so it will result in a Division by Zero exception. You may
modify your expression below
=IIf(Fields!MyValue.Value = 0, 0, Fields!MyValue) /
IIf(Fields!MyTotal.Value = 0, 1, Fields!MyTotal.Value)
Thank you for your patience and cooperation. If you have any questions or
concerns, don't hesitate to let me know. We are always here to be of
assistance!

Generate Percentage

I have a report that shows number of units in use for a given day. You can
then drill down and view the number of units in use for a given hour. I want
to display what percentage of units are in use for the given hour. Ex:
Yesterday there were 4 units in use. If you drill down you see that 1 unit
was in use @. 10AM. For 10AM, I want to display that 25% (1/4) of units were
in use.
The problem is I cannot seem to reference the SUM(UnitsInUse) value, which
is 4, that is displayed in the group header. How can I do this?
TIA
PaulPaul,
To achive this u need to pass this value as a parameter to drill down
report and use this value for your calculation in next report. As far as I
know there is now way for you to access field of other report.
Hope this helps
Thanks,
Mahesh

Generate 'calculated values' for rows within Stored Procedure

I'm having a problem with generating a 'calculated' percentage value as
noted in the sample output below:
#######
Luxury822.34602709630
Standard433.34602709630
Custom397.34602709630
Modified285.34602709630
Other222.34602709630
More...676.34602709630
#######
The 'VP_VClass' column (left) correctly shows each classification, and
provides the correct count for each. However the percentage for each
classification is shown 'incorrectly' as it should be a percentage for each
instead of for the 'sum' of the classifications count, like so:
#######
Luxury822.10032954961
Standard433.05284999389
#######
The SP is as follows, where the function [dbo.udf_Current_InventoryFunction
()] provides the 'total' count (which in the examples above is 8,193).
#######
ALTER PROCEDURE dbo.usp_VClass_Breakdown
AS
SELECT TOP 100 PERCENT VP_VClass, COUNT(VP_VClass) AS CountOfVP_VClass,
(SELECT CAST(COUNT(VP_VClass) AS NUMERIC)
FROM dbo.vw_VClass_BreakdownView
WHERE (Active = 1) AND (Current = 1)) /
(SELECT *
FROM dbo.udf_Current_InventoryFunction
()) AS Expr1
FROM dbo.vw_VClass_BreakdownView
WHERE (Active = 1) AND (Current = 1)
GROUP BY VP_VClass
ORDER BY COUNT(VP_VClass) DESC
#######
Any thoughts or suggestions would be appreciated. Thanks.

Hi,
The Query can be re-written as:
=============================
ALTER PROCEDURE dbo.usp_VClass_Breakdown
AS
SELECT VP_VClass, COUNT(VP_VClass) AS CountOfVP_VClass, COUNT(VP_VClass) /
udf_Current_InventoryFunction() PercentOfVP
FROM dbo.vw_VClass_BreakdownView
WHERE (Active = 1) AND (Current = 1)
GROUP BY VP_VClass
ORDER BY COUNT(VP_VClass) DESC
================
I believe this addressed your question. If there are any more problem please
revert back
thanks and regards
