Hopefully this is simple. I know how to choose a value in the property section for a collected threshold to group all values under a certain percentage; however, I want to know if it's possible to set 2 values. If so, how do I go about doing that?
For instance, group all values with a value of 1-3% into a pie slice and group all values with a value of 3%-10% into another pie slice with the rest of the values each getting their own pie slice.
As a caveat, while the answer below isn't hard to set up it is a bit ugly and not great for maintainability or efficiency. I'd consider working on the query end to break out the categories.
You can set up the chart as a subreport and pass it the total as a hidden parameter (as you can't directly use aggregate functions in calculated fields or grouping expressions). Then use a category grouping expression similar to the following, changing field names as appropriate:
=IIF(Fields!Value.Value/Parameters!Total.Value<0.03,"Other (<3%)",IIF(Fields!Value.Value/Parameters!Total.Value<0.10,"Other (<10%)",Fields!Name.Value))
If your dataset doesn't rely on any parameters, you could also skip the subreport and just set up an extra dataset that grabs the sum total and have an internal parameter default to that value.

I have a crosstab query which returns results based on consumer demand for a bunch of material numbers. The material numbers become my field names in the crosstab query, and later the values from those fields are displayed in a form.
In the form, I display the value in a textbox. There are a couple of these textboxes where I need to sum the total of two or more values from these fields. Not a big deal it's a simple expression. For example (in the Control Source property): =[H123457] + [H123456].
This works well UNTIL there is no demand for a particular material number. In this case, the field doesn't show up in the crosstab query and I'm left trying to sum two fields where one doesn't exist.
I've tried IIf(IsError([H123456]), 0, [H123456]), Null expressions, Nz function, etc but cannot figure out how to dynamically solve the #Name issue that ends up populating the text box.
Essentially what I want is for a 0 value for the field that doesn't exist, so I can add it to the value where the field DOES exist - is this possible?
Regards!
June7 provided the answer in the allenbrowne.com link. Essentially, you need to add all of the possible field names to the Column Headings property in the crosstab query property window. Then it's a simple matter of adding an Nz() function to handle null values.
Thanks June7!
I'm using MS Report Builder v3.0 to create a report. As part of this report, I have a multi-valued parameter (named #Diagnoses). The labels and some of the values (truncated by the size of the display boxes) of this parameter are shown below:
What I would like to be able to do is display the labels / values the user chooses in a 2-column tablix (I've tried using separate textboxes for the labels / values but the results are mis-aligned).
However, this does not appear to be straightforward. The closest method I've found is this one, which stores the user's choices in an internal parameter in xml format, then queries this parameter to produce a dataset from the xml.
So, I created the xml-producing internal parameter like this:
...and I've created a dataset based on this data, with the following query:
But now when I put these values into a tablix, the labels and values are now on separate rows, like this:
Does anyone have a straightforward way of sorting this out?

OK - I've solved it (it's not pretty, but it works!)
Basically, the problem comes from having to use the join statement when creating the xml - you can't really put both the label information and the value information on the same row in the xml.
To get round this, you have to use two internal parameters to create two datasets - one for the labels column, one for the values column. The method for creating these is essentially the same as that shown above, except for the values parameter, the expression for the default value is:
...and for the labels parameter, it's this:
(by the way, make sure you set the available values to "None" for internal / hidden parameters - the expressions here are for the default values)
Then, when you create the values dataset, you use the following syntax in its query:
...and similarly for the labels dataset.
Finally, in the report, you create one matrix from each of the two datasets, then put them next to each other, using fixed row heights and setting "can shrink" / "can grow" to false so that they look like they're in the same table:
I hope this helps somebody!
I am trying to dynamically format the labels on my SSRS charts based on the underlying value. I'm trying to do this in two scenarios, one to format dates as ordinals and another to choose the appropriate number of decimal places based on actual values present. However, when I use the expression editor with an expression something like this...
=IIF(MAX(ABS(Fields![axisfield].Value))<2, "0.0%","0%")
...the Fields![axisfield].Value is always returning the first value from the dataset, meaning, in this example, if the first value is less than two, the labels will be formatted with one decimal place, even if it is the only one less than two. (So the 'MAX' function is essentially irrelevant.)
That example is attempting to set the overall formatting based on the largest data point in the series, in this next one I'm trying to format each label separately to get Ordinal dates (i.e. 1st, 2nd, etc, and yes, this formula is incomplete: it doesn't need to be to illustrate the problem):
="dd"+IIF(DatePart("d", Fields!date.Value)=1,"\s\t"
,IIF(DatePart("d", Fields!date.Value)=2,"\n\d"
,IIF(DatePart("d", Fields!date.Value)=3,"\r\d"
,"\t\h")))
This will give 1st, 2st, 3st and so on, as the first row in the dataset is for the first.
So, my question is, how do I get round this and, in the first example get the true maximum, and in the second reference the actual value being formatted?
Thanks!
I've had the same issues with using custom functions for setting label visibility. (see my entry for this: How to Display Only 1 Value Label in SSRS 2012 Calculated/Derived Series? )
I believe the issue is that data and fields are bound to the underlying data series but are not bound and accessible within the label itself.
You should be able to set the formatting in the function for the series data itself (as in the 2nd example) and then just set data labels, which will use the underlying series field value. An example with your data might be something like the following, which returns the values with the format:
="dd"+IIF(DatePart("d", Fields!date.Value)=1,Format(Fields!date.Value, "\s\t")
,IIF(DatePart("d", Fields!date.Value)=2,Format(Fields!date.Value,"\n\d")
,IIF(DatePart("d", Fields!date.Value)=3,Format(Fields!date.Value, "\r\d")
,Format(Fields!date.Value,"\t\h"))))
In the first example, you can get the max value to referring to the Dataset, as opposed to the field. Your code would then be:
=IIF(ABS(MAX(Fields![axisfield].Value, "YourDatasetName"))<2, "0.0%","0%")
(I changed the order of operations for Abs and Max because you have to use an aggregate function when referring to the whole dataset. Only then can you refer to the specific value.)

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.
I'm working on a rather complex report in Sql Server Reporting Services. My SP returns a dynamic number of columns each of which are dynamically named.
Basically think of a time keeping application. Each column that is dynamic represents a time bucket that time was charged to for that team. If no time was charged to that bucket for the period of time the report covers it doesn't show. Each bucket has its own identifier which i need to be the column headers.
I have an SP that returns this all. It does it by doing a bit of dynamic SQL with an exec statement (ugly i know but I'm on SQL 2000 so a PIVOT option wouldn't work)
I can have an indefinite number of buckets and any or all might show.
I found this - http://www.codeproject.com/KB/reporting-services/DynamicReport.aspx - which is helpful but in the example he has a finite number of columns and he just hides or shows them according to which ones have values. In my case i have a variable number of columns so somehow i need the report to add columns.
Any thoughts?
As long as you know a maximum number of columns, it's possible to do this after a fashion.
First, name the columns with a result from your query, so you can either pass it in to the query or derive it there. Second, just build out the report as if it had the maximum number of columns, and hide them if they are empty.
For example, I had to build a report that would report monthly sales numbers for up to a year, but the months weren't necessarily starting in January. I passed back the month name in one column, followed by the numbers for my report. On the .rdl, I built out 12 sets of columns, one for each possible month, and just used an expression to hide the column if it were empty. The result is the report appears to expand out to the number of columns needed.
Of course, it's not really dynamic in the sense that it can expand out as far as you need without knowing the upper bound.
This can be done. I did this and it works fine.
You don't have to know the maximum number of columns or show and hide columns in my approach. Use a matrix and modify your sp to return dynamic data to the structure mentioned in this blog post http://sonalimendis.blogspot.com/2011/07/dynamic-column-rdls.html
Build 2 related Datasets, first one for the report content, and the second one for the list of its column labels.
The Dataset of the report content must have a fixed number of columns and name. You can allocate some maximum number of columns.
In this example I have the first 2 columns as fixed, or always visible, and a maximum of 4 columns to be displayed by choice through a multivalued parameter, or depends on the query conditions. And as usual, we may have a total as well. So, it may look like this:
Fixed01, Fixed02, Dyna01, Dyna02, Dyna03, Dyna04, Total
The second Dataset with its values will look like this:
Name Label
---- -----
Dyna01 Label01
Dyna02 Label02
Dyna03 Label03
I have omitted the 4th Label to demonstrate that not all columns are being used by a certain query condition. Remember that both Datasets are meant to be related to the same query.
Now create a parameter named, say, #columns; populate its Available Values and Default Values with the second Dataset.
For each of those 4 dynamic columns, set the column visibility with the following expression:
=IIf(InStr(join(Parameters!columns.Value,","),"Dyna01"),false,true)
And for each of their column header Text Boxes, use the following expression:
=Lookup("Dyna01", Fields!Name.Value, Fields!Label.Value, "dsColumns")
As for the Total, here is the expression for its visibility:
= IIf(InStr(join(Parameters!columns.Value, ","), "Dyna01"), false, true)
AndAlso IIf(InStr(join(Parameters!columns.Value, ","), "Dyna02"), false, true)
AndAlso IIf(InStr(join(Parameters!columns.Value, ","), "Dyna03"), false, true)
AndAlso IIf(InStr(join(Parameters!columns.Value, ","), "Dyna04"), false, true)
And here is for its values:
= IIf(InStr(join(Parameters!columns.Value, ","), "Dyna01"), Fields!C01.Value, 0)
+ IIf(InStr(join(Parameters!columns.Value, ","), "Dyna02"), Fields!C02.Value, 0)
+ IIf(InStr(join(Parameters!columns.Value, ","), "Dyna03"), Fields!C03.Value, 0)
+ IIf(InStr(join(Parameters!columns.Value, ","), "Dyna04"), Fields!C04.Value, 0)
That's all, hope it helps.
Bonus, that second Dataset, dsColumns, can also hold other column attributes, such as: color, width, fonts, etc.
I think the best way to do it is add all the columns in your table and edit the visibility property of it with the help of arguments that you get from your SP..this will solve the purpose of dynamic column but when viewing the report you will get a lot of white-space which you can solve with SSRS - Keep a table the same width when hiding columns dynamically? and your report will be ready
I've had the need to do this in the past and the conclusion I came to is "you can't", however I'm not positive about that. If you find a solution, I'd love to hear about it.
An issue that comes to mind is that you need to define the report using the names of the columns that you're going to get back from the stored proc, and if you don't know those names or how many there are, how can you define the report?
The only idea I had on how to do this is to dynamically create the report definition (.rdl file) via C#, but at the time, I wasn't able to find an MS API for doing so, and I doubt one exists now. I found an open source one, but I didn't pursue that route.
