create an IIF statement and tested with static values. This verified my syntax was correct but I still see the error on my reports. =IIF(Sum(Fields!CY_Dollars.Value)=0, 0, (Sum(Fields!CY_Dollars.Value) - Sum(Fields!PY_Dollars.Value))/(Sum(Fields!PY_Dollars.Value))) So I'm taking Current year dollars, subtracting Previous year dollars, and dividing that total by previous year dollars to get the percentage change. Is there a trick to this that I'm not getting?! reporting-services ssrs-tablix ssrs-expression share|improve this question edited Dec 3 '15 at 5:16 pedram 3,30131840 asked Oct 4 '13 at 19:19 d90 3342415 You mentioned that there are nulls in your data? Try nesting each field call in a NULL replacement function. For example, I would the format IIF(Fields!PY_Dollars.Value = Nothing, 0, Fields!PY_Dollars.Value = Nothing) for each Fields!PY_Dollars.Value in the current formula. Better yet, handle the nulls in the source query instead. –Eric Hauenstein Oct 4 '13 at 19:59 The condition in your IIF statement is not checking for zero denominator (you are checking for zero in CY,
single IIf statement does not work because it evaluates both results before deciding which one to act on. For example, when the denominator is 0, this returns an error: =IIf ( Fields!Denominator.Value = 0

,NOTHING ,Fields!Numerator.Value / Fields!Denominator.Value ) (Actually, it either returns "#Error", "Infinity", "-Infinity", or "NaN" divide by zero error encountered sql server 2008 depending on the data types involved. My next blog post will provide more detail on that. Let's assume in this blog that add function to ssrs report the numerator and denominator are both DECIMAL, which will result in "#Error" when the denominator is zero.) Pros and Cons Here are the pros and cons of the different techniques. If you have some more http://stackoverflow.com/questions/19189132/ssrs-expression-divide-by-zero-error insight on one of these, or know of another technique, let me know in the comments. Technique #1 - Nested IIf Statement The first and most commonly used workaround is the nested IIf statement: =IIf ( Fields!Denominator.Value = 0 ,NOTHING ,Fields!Numerator.Value / IIf ( Fields!Denominator.Value = 0 ,1 ,Fields!Denominator.Value ) ) As you can see, this works because when the FALSE condition of the first IIf is evaluated, it does not http://bismiths.com/blog/how-to-handle-divide-by-zero-in-ssrs/ try to divide by zero. Technique #2 - Math Trick =IIf ( Fields!Denominator.Value = 0 ,NOTHING ,Fields!Numerator.Value * (Fields!Denominator.Value ^ -1) ) As you know, in algebra: X * (Y ^ -1) = X * (1 / Y) = X / Y So it is the same as dividing by the denominator. But why does it work when the denominator is 0? This works because (0 ^ -1) evaluates to "Infinity" in SSRS regardless of the data type. Be aware this does not work in other places, like T-SQL: Or the plain ol' Windows calculator: Or the TI-83 calculator: Interestingly, however, it does work in PowerShell: I would never expect this to work because it doesn't really make mathematical sense! Dividing by zero and raising 0 to the power of -1 are supposed to be the same thing. If you are a stickler for math, you may be a little hesitant to use this trick in your reports. Technique #3 - Custom Code You may prefer to return 0 instead of NOTHING. If so, you have the additional option of using custom code: ............................ Public Shared Function SafeDivision(ByVal numerator as Decimal, ByVal denominator As Decimal) As Decimal If denominator = 0 Then SafeDivision = 0
November 25, 2011 by jsalvo I encountered a divide-by-zero error while working on an SSRS report and thought the issue could easily be resolved http://salvoz.com/blog/2011/11/25/ssrs-checking-for-divide-by-zero-using-custom-code/ using IIF with code similar to the following: =IIF(Fields!Denominator.Value = 0, 0, Fields!Numerator.Value/Fields!Denominator.Value) I soon realized that this does not resolve the issue. It appears that all parameters in the https://www.experts-exchange.com/questions/27992693/getting-warning-attempted-to-divide-by-zero.html IIF function are evaluated regardless if the first parameter evaluates to true or false. Therefore, the divide-by-zero was still occurring. After doing some research, I decided that the best option divide by to avoid the divide-by-zero error is to implement custom code. Note: The following screen shots are from Report Builder 3.0 The first step is to open the Report Properties window. You can access the report properties by clicking anywhere outside of the report body. If you still cannot see the Report Properties window, make sure you have the ‘Properties’ option divide by zero checked in the ‘View’ tab. The Report Properties window is displayed below. In the Code text box, click the ellipse […]. You may need to click on the Code text box first to see the ellipse button. Next, select ‘Code’ in the left hand menu if it is not already selected. Paste the code (displayed below screen shot) in the Custom code field. Function Divide(Numerator as Double, Denominator as Double) If Denominator = 0 Then Return 0 Else Return Numerator/Denominator End If End Function Now that you’ve created the custom code, you can begin to use the code in your report. The following is an example of how you can use the Divide function in a text box expression: =Code.Divide(Fields!CurrentYearSales.Value-Fields!PriorYearSales.Value,Fields!PriorYearSales.Value)*100 Share this:More This entry was posted in Database and BI, Technology and tagged SSRS by jsalvo.

IIf(CDec(Sum(IIf(Fields!OrderLineStatus.Value = "OPEN", Fields!OrderBalanceQty.Value, CDec(0)))) <> 0, (CDec(Sum(IIf(Fields!OrderLineStatus.Value = "OPEN", (Fields!OrderBalanceQty.Value * Fields!OrderPrice.Value), CDec(0)))) / CDec(Sum(IIf(Fields!OrderLineStatus.Value = "OPEN", Fields!OrderBalanceQty.Value, CDec(0))))), 0) Select all Open in new window Thank you 0 Question by:metropia Facebook Twitter LinkedIn Google LVL 37 Best Solution byValentinoV ryanmccauley: are you sure that IFERROR is a standard SSRS function?

Alternatively, you could use the little known IFERROR() function to replace your error with a suitable value: =IFERROR(Your Expression Here, 0) Select all Open in new window And it would give you a zero value if the expression causes a calculation error (in this case, divide by zero). 0 LVL 21 Overall: Level 21 MS SQL Server 2005 10 SSR
