My report has two datasets, main one and a second dataset (which holds only one row). I need to count how many values of a certain column in the main dataset are below a value taken from the second dataset. The expression I use is:
=Count(IIf(Fields!TestValue.Value < First(Fields!NetUnitWeight.Value, "SecondDataSet"), 1, Nothing), "MainDataSet")
& " of " & CountRows("MainDataSet")
But I get the following error:
[rsAggregateofAggregate] The Value expression for the textrun 'Textbox1.Paragraphs[0].TextRuns[0]' contains an aggregate function (or RunningValue or RowNumber functions) in the argument to another aggregate function (or RunningValue). Aggregate functions cannot be nested inside other aggregate functions.
I tried to solve it by putting First(Fields!NetUnitWeight.Value, "SecondDataSet") in a report variable, but this didn't work. How can I solve it?
OK, I found a workaround. I added a new report parameter, right-clicked it to open its properties, then clicked "Default Values". I selected "Get values from a query" and chose the dataset and value field I needed. Now this expression works without errors:
=Count(IIf(Fields!TestValue.Value < Parameters!NetUnitWeight.Value, 1, Nothing), "MainDataSet")
& " of " & CountRows("MainDataSet")

This SO link, WHERE Caluse in SSRS expression, verifies that my syntax is correct yet I get this error:
"An error occurred during local report processing.
The definition of the report is invalid.
The Value expression for the text box 'txt1A_EMA' uses an aggregate expression without a scope. A scope is required for all aggregates used outside of a data region unless the report contains exactly one dataset."
My expression:
=Sum(IIF((Fields!COU_EMA.Value, "CA_Summary") = 1, (Fields!Amount.Value, "CA_Summary"), 0))
There are 3 Datasets in my report. The one I want is "CA_Summary" and the expression above was built with the expression builder.
The field, (Fields!COU_EMA.Value, "CA_Summary"), is a boolean (1 or 0) and I get error either with a 1 or a "true" (no quotes).
I probably could fix it if I knew what the definition of "scope" is. . . maybe.
The scope is where you want to look in order to get the values you're looking for. It could be a data set, group, etc. In your expression it appears CA_Summary is the scope.
I would try modifying the expression a bit. Since you say COU_EMA is bit field, maybe use TRUE. This is also assuming the matrix is using the data set CA_Summary.
=Sum(IIF(Fields!COU_EMA.Value = TRUE, Fields!Amount.Value, 0))
If your matrix isn't using that data set and it still doesn't work try
=Sum(IIF(Fields!COU_EMA.Value = TRUE, Fields!Amount.Value, 0),"CA_Summary")
I have 3 datasets in my project. I am trying to create an expression in a standalone textbox that reports "Error Found!" if the field.value is populated and "No Errors" if the field.value is blank.
=SUM(IIF(Fields!Account.Value = "","No Errors","Errors Found!"),"Account")
This is kicking back a "Report item expressions can only refer to fields within the current dataset scope or, if inside an aggregate, the specified dataset scope." error.
To avoid issues with multiple datasets, I added the SUM and the "Account" to reference the correct dataset.
If I were to replace my TRUE/FALSE with "1,0", the expression works.
Try:
=IIF(Isnothing(First(Fields!Account.Value,"Account")),"No Errors","Errors Found!")
Or you can use:
=IIF(CountRows("Account")=0,"No Errors","Errors Found!")
Where Account is the name of the dataset.
Let me know if this helps.
I have the following switch statement within an SSRS report, but it errors out when I run the report.
Basically Parameter 1 is a multi value parameter, and when the parameter has two values selected where they are two distinct values, I want a certain text to appear.
=SWITCH(Parameters!Parameter1.Count = 2 AND Parameters!Parameter1.Value(0) = "TEXT1-NY" AND Parameters!Parameter1.Value(1) = "TEXT2-LA" , "Combined (NY & LA)"
, True, JOIN(Parameters!Parameter1.Label,"& ")
)
Additionally, regardless of the numbers that are selected (i.e if there were 6 parameters that were selected), is it possible that these two parameters would be replaced with that particular text followed by , and then names of other parameter values?
First of all, good job working out the expression that you have. You're on the right track, but expressions don't have a programmatic way to loop through the values of the parameter.
One option to do specifically what you asked would be to add a custom function to the Code section of your report that could loop through the parameter values.
Another option would be to simply UNION this "Combined (NY & LA)" value to your dataset so that it is available as one of the options.
I'm very confused by this situation, i've written quite a few IIF statements and always get them to work. I have two columns in my dataset called CATEGORY and PCT, what i'm trying to do is return the PCT value for only one specific value in CATEGORY.
For example, I have the following table of data
Category PCT
A .50
B .75
I have placed a textbox on my report and have written the following expression to return the PCT value if Category = B, like so:
=IIF(Fields!Category.Value = "B", Fields!PCT.Value, " ")
For some reason this expression returns empty every single time. When I just put Fields!Category.Value in the textbox as a test then the value A returns which is as expected.
I'm really thrown-off by this and I know i'm missing something very simple - can someone help?
Its important that we understand the context of the textbox as the expression seems valid.
If you placed a single textbox on your report and used your above expression (with references to the datasets) ONLY the first row of your dataset will be evaluated. In which case the expression will always evaluate to the same result.
Can you confirm that the control you are using is indeed a textbox? If it is then i believe you do need a reference to the dataset and the expression will look more like this:
=iif(First(Fields!Category.Value, "datasetName") = "B", First(Fields!PCT.Value, "datasetName"), " ")
This would only evaluate the first row in your dataset.
If you were to do this in a tablix using your original expression then it should work.
Customer wants me to repeat the parameter values in the page header of the report. But if they just choose "Select All" on a multi-valued parameter, they want the text "Any" listed.
For example, one parameter has a fixed set of 9 values. I hard-coded the expression for a text box to:
="Room Size: " &
iif(Parameters!pRoomCap.Count=9,
"Any",
Join(Parameters!pRoomCap.Value, ", "))
How can I do this if the parameter source is a query of unknown size?
Try this out. You need to compare the total number of parameters in the dataset to the count of selected parameters. The following assumes that your multivalue parameter is using a dataset called "dsRoomSizes"
="Room Size: "
& iif(Parameters!pRoomCap.Count = count(Fields!pRoomCap.Value,"dsRoomSizes"),
"Any",
Join(Parameters!pRoomCap.Value, ", "))
This expression will work in the page header/footer.
UPDATE
In the interests of finding a solution to your problem, the following should work for you. It feels hackish and I encourage you to keep research alternative methods but this will work:
Create a second multivalue parameter and name it something like "pRoomCap_hidden".
The source of the parameter is the exact same query
In the parameter properties, setting the default values to the same query
Important: Set the parameter visibility to hidden
This will create a second multivalue parameter in your report that is exactly the same as your initial multivalue parameter only this parameter list will have all values selected by default.
Enter the following expression in a textbox in your header:
=IIF(Parameters!pRoomCap.Count = Parameters!pRoomCap_hidden.Count,"All",Join(Parameters!ReportParameter1.Value,", "))
The above will compare the selected values in each parameter list. If the lists contain the same selected values then that indicates that "All" have been selected in the first list.
Like I said, it is hackish but it definitely works. Until you are upgraded to 2008, this might not be a bad workaround for you.
Can you compare the count of the parameter to the count of the dataset you pull the parameter values from?
I unioned my dataset for the parameters with one which I created manually with a "select" statement - I was then able to force the value to be something like -1 or null.
Then simply check if the parameter contains -1 or null and replace the value in the header with the replacement text.
BTW- I am now using SSRS 2008 R2 and this solution worked for me. My report uses three datasets; but only one in the tabilx that I needed to hide a row in. After long hours of searching and many, many, many unhelpful for wrong answers; the solution of creating a identical parameter only hidden (I marked it as internal) and then comparing to the exposed one is brilliant and easy.
Thank you very much!
