I'm trying to calculate the total of cost in RDLC report using expressions
I applied the following and it works fine :
=SUM(Val(Fields!PCOST.Value))
But I tried to apply another expression to calculate the cost but with a condition like below :
=IIf(Fields!Active.Value =False, SUM(Val(Fields!PCOST.Value)),0)
but only I got 0.00?
can anyone explain why?
the table [Active] field type is bit
You need to sum the result of the IIF rather than the other way round. I've not tested this but I think the following should work...
=SUM(IIf(Fields!Active.Value =False, Val(Fields!PCOST.Value),0))

I have been working on this for days without being able to solve yet. It's probably simple if you know what you're doing. I'm simply trying to make a standalone formula that is not in a tablix or anything, it's just in a textbox.
Here is an example of my Dataset called Dataset1:
What I am trying to get is a sum of the Actual Cost when the Category is Labor from Dataset1. My current expression is:
=Sum(iif(Fields!Category.Value="Labor", Fields!ActualCost.Value, 0), "Dataset1")
I refer to Dataset1 as my scope because otherwise, I get an error about using an aggregate expression without a scope.
The report runs but shows #Error in the textbox that has my expression in it. When I replace Fields!ActualCost.Value with a 1, I get the answer, 5, which is the correct number of rows with Labor as the Category. But it won't let me sum the numbers in the ActualCost column where Category is Labor.
Any ideas as to what I'm doing wrong? I feel like it's something to do with aggregating, but I'm not sure. Thanks!
It may have to do with the datatype of fields!ActualCost.Value. If that field is a decimal (regardless of how you have it formatted), try using cdec(0) instead of just 0 in your expression.
I have tried to create a calculated field that will show the number of customer transactions processed within 15 minutes.
I have added the expression:
=count(fields!wait.Value<15)
However, when I run the query I'm getting the error message : 'expression used for the calculated field includes an aggregate RowNumber...'
Can you advise please on how to create a calculated field so I can capture the value I want?
I have tried = SUM(IIF(Fields!wait.Value < 15 , 1, 0)) to no avail.
With many thanks.
Calculated fields added to datasets can't have aggregate functions. The calculated field is essentially adding an extra column to your dataset. It sounds like you may want a variable? Used elsewhere in the report, your second expression would work, or the similar
=Count(IIf(Fields!wait.Value<15, 1, Nothing))
would work too.
In SSRS, I'm trying to calculate the average number of months a client used a program. The programID is the parameter for the whole report. I'm trying to achieve this (not written with real syntax):
=Avg(Fields!length_of_stay.Value, 0))/30.0 WHERE programid = #ProgramID
Using this question, I came up the the following code which is producing an incorrect answer. I tested in SSMS to get the actual values to compare to SSRS results.
=Avg(IIF(Fields!programid.Value = Parameters!ProgramID.Value, Fields!Length_of_Stay.Value, 0))/30.0
The "/30" is used since the value is in days and I need months. I think the issue is using the parameter value chosen; this is my first report trying to calculate expressions with parameters.
Avg returns the average of all non-null numeric values. 0 is not null so it gets included in the average, distorting your result for every row with a different PragramId. Try using Nothing instead:
=Avg(IIF(Fields!programid.Value = Parameters!ProgramID.Value, Fields!Length_of_Stay.Value, Nothing))/30.0

I would like to add and expression that calculates a value based on a certain value. I have a dataset with the name DSSPend that has to columns one is the Area and the other spend. Now I would like to calculate the spend based on certain area values.
I tried something like this but does not seem to work
=Iif((Fields!Area.Value, "DSSSpend") IN ('New York','Miami','Texas') = SUM(Fields!Spend.Value, "DSSSpend"), 0)
=sum(iif((Fields!Area.Value = "New York" or Fields!Area.Value = "Miami" or Fields!Area.Value = "Texas"),
CDec(Fields!Spend.Value), CDec(0)))
There is no IN operator in SSRS expressions. You can achieve the same goal by using OR.
Also, your SUM aggregation needs to go outside the IIF. Your expression would evaluate the first record only rather than going through each record in the dataset and then aggregating. The expression I have written above goes through the entire dataset, summing either the value in the Spend field or 0, depending on the value of Area.
Update: If you were getting an error before, it was probably because it wasn't seeing your amounts as numbers. By converting them explicitly, you should get around this issue.
My dataset currently has 12 rows of data. Each representing data for a month. I would like to have variance of a column between to rows, the rows being last & last but one i.e., latest month and previous month's data.
It could have been simple if I were to work on tablix but thats not the case. I want those values for a textbox.
Any ideas on it anyone?
I hope you are using SSRS 2008R2:
R2 introduced the Lookup function that is perfect for this scenario.
=Lookup( Fields!ProductUID.Value ,Fields!ProductID.Value,Fields!Price.Value,"PriceDataSet")
The Lookup function above will evaluate the first parameter ("Fields!ProductUID.Value") in the current dataset, then look for a matching value in the field specified in the second parameter ("Fields!ProductID.Value") in the dataset specified in the fourth parameter. The value of the third parameter is then evaluated in that row of the dataset and returned.
A little convoluted, but very helpful.
In your case, you can use this in a textbox with a calculated a static number:
=Lookup(
Month(DateAdd(DateInterval.Month, -1, GetDate())),
Fields!MonthID.Value,
Fields!Name.Value,
"DataSet1")
This should calculate a number for last month, then look for a match in DataSet1.
In this example I have a tablix with Statecode and name as below
enter image description here
Suppose you want to display the name of state of CA, write an expression as -
=Lookup(
"CA" ,
Fields!StateCode.Value,
Fields!StateName.Value,
"ReportData"
)
This will return 'California' in the text box
I ran across this post while trying to solve a similar problem but with columns of double data type. Not sure why but SSRS did not want to return my first row using LOOKUP in combination with ROW_NUMBER in SQL(If someone can solve that all the better). I ended up using a SUM(IIF) instead. Hopefully, this is useful for someone else.
=Sum(IIF(Fields!RowNum.Value=1,CDBL(Fields!MyNumericColumn.Value),CDBL(0)))
Note: If SSRS complains about data types, just cast both parts of the IIF to the desired data type.
