I want to create a report where my report's fields should change according to my input parameter values.
For example, if I select 2 months, there should be 2 fields in result, having month wise calculation. If I select 3 weeks, there should be 3 fields each for each weeks calculation instead of the 2 months field.
How do I achieve this?
I'm still a beginner at SSRS, but I've heard of a few ways to handle this:
To a certain extent, you're really talking about separate queries, depending on the parameters. So, use a dynamic query (build the query up as a string expression). The simplest way I saw was to use IIF in the expression to choose one or the other stored procedure based on the parameter values.
To the extent that it's pretty much the same query, but you want different columns visible, then you can tie the visibility of the columns to an expression based on the parameter values.
If too much of the structure of the report differs based on the parameters, then you can use multiple reports. Have one front-end report that calls on one of the other reports based on the parameter values, passing the parameter values to the other report.
I hope that helps. If you've already figured out a solution, then please tell me!

I have an SSRS report that combines 5 reports into one. Each report is populated from a different stored procedure. The first page is a summary that is to provide a record count from each report. I've created fields in the stored procedure that provides the counts for each individual report: phycount and nonphyscount. I'm trying to create a table similar to this:
Active comes from one data set, Initial comes from another, Recert comes from another, etc.
I've been playing around with the Lookup and LookupSet but I'm just getting errors, plus I'm not sure if that's even the right direction.
Does anyone know how to do this?
Lookup and Lookupset are more for getting specific values out of a dataset. Very useful but not necessary for what you're trying to accomplish.
You can use aggregate functions SUM and COUNT to accomplish what you want to do. The cool thing about these functions is you can actually embed IIF statements inside of them.
I'm not sure exactly how your datasets look and are named but it would be something like this...
SUM(IIF(Fields!Type.Value = "PhyCount", 1, 0), "Active")
The sum function goes through every row of your dataset and sums the values you pass to it. The iif statement checks to see if the type field in the dataset is "PhyCount". If so, it returns 1, if not, 0. Since this will happen for every row, your SUM function will return a count of each row with status active.
edit: "Active" after the iif statement specifies the name of the dataset.
EDIT AGAIN: This solution apparently does not work in SSRS 2008.
I am building a report in Microsoft SSRS 2016; I have multiple groups in my report,
all these groupings are done via (the same) set of parameters. You can see the screen
shot below:
1) I have 3 groups in SSRS 2016 Report Designer.
2) All 3 groups use the same expression (using parameters) to group report.
In a nutshell, if the parameter value is X, it is grouped by X; if that parameter value is Y, it is grouped by Y; I do this for many groups, creating many parameter.
I will have many more groups in the future, and hence many more parameter options,as the report grows. I am trying to figure out a way to optimize this SSRS 2016 report by writing this code JUST ONCE.
I tried to add a Report Variable as shown below:
Now I have a new Report Variable (GV2) that stores this code with Switch operator.
I now try to use this Report Variable across many different groups.
I get this error:
Variable values cannot be used in group expressions
Is there any other way to do this? I need to optimize this sort of parameterized grouping.
May be writing some custom codes in SSRS; if so, can you provide the code (my knowledge in .Net is zero!)
Thanks
You can use a parameter to do this.
Set up a parameter for your group by options
In the Available Values, add the things you want to group by
For the value section of these, put the name of the field you want to group by. For example - if you want to group by Fields!Region_Name.Value, you set up your parameter with Region_Name in the value field.
In your group expression on the tablix, use =Fields(Parameter!GroupBy.Value).Value
Now when you select the value from the parameter, it will group by that. You simply have to add new values to the GroupBy parameter in the future to add more options.
I need to add a field to a SSRS report. I tried modifying the dataset (query) but the results prouduced insane results, with zipcodes showing up in the name fields and names showing up in a datetime field. I suspect it is because of the groups but I don't understand how they work. The Dataset is created by 4 selects. The first 3 insert into temp tables and the fourth pulls from it. I suspect that I will have to re-write the query but it would be nice if I could use it as is with modifications. Either way I need to understand the groups.
I read
Data Region Cells, Data Region and Understanding Groups. Aside from the fact that they use terms specific to SSRS without defining them they are so undetailed I doubt many people who do not already understand SSRS can get anything out of them.
I did not write this report but I must modify it. I understand SQL well. Not so much with SSRS.
Can anyone explain how to find out what the Row Groups mean? Mine look like this:
Here is the tablix
I have a very simple task. I have two datsets. The first is a single value that has returned me a number of calls that has been made. The second is a list of targets. I want to be able to divide the first number of calls by its call target in order to calculate the total %.
The lookups of these are dependant on the criteria that is selected in the report itself. I know it's possible to do inside SQL its just a huge pain in the ass. I want to be able to calculate two fields and I thought something so simple would be a breeze for SSRS but apparently not. So the error i get is:
*The expression used for the calculated field'=fields!DMCP.Value / FIRST(Fields!DMCTarget.Value,"AllTargets")' includes an aggregate,rownumber,runningvalue, previous or lookup function. aggregate,rownumber,runningvalue, previous and lookup functions cannot be used in calculated field expressions.*
I can take the first function out but it doesn't help me. It says it can only calculate in the same dataset, problem is these values can never co-exist in the same dataset. Anything I can do????
Thanks in advance
I had a problem in creating the Dynamic report in SSRS. My problem is:
In a table I have stored SQL scripts with the column SQLScripts. If you execute these SQL scripts you get different number of columns for each script.
My problem is, I have one report with buttons of these scripts, for example test1, test2...like that. If you press test1 button this should take the test one SQL script and should display the report with appropiate columns in that sqlscripts.
I can't create individual reports for each test report, they are plenty. Are there any options for me to solve this problem...
The only way I've been able to get this to work sofar is:
Each report has 2 datasets.
ReportData
DataHeaders
The "DataHeaders" need to have the proper name of the datafields in "ReportData". Be careful since SSRS replaces blanks and special characters with "_"
Now, create a table (or matrix) and drag the DataHeaders as the Columns of your report. (This should be a grouped column). If you run it at this point, you'll see all your columns without any data. Now comes the magic:
Create another report that takes a "DataField" parameter. Create another table or matrix within this report and set it's dataset property to be "ReportData". In the DATA cell for the table, set it to the expression =Fields(Parameters!DataField.Value).Value
Now go back to your first report. Right click and insert a subreport. Right click on the subreport and select "Subreport Properties". Under general, select the second report you created to be used as the subreport. Under parameters, select the DataField parameter and set its value to something like =Fields!DataField.Value
In my case I did some formatting in this expression to fix the above mentioned issue with spaces and special characters, since my stored procedure was initially used in ASP.NET and this was just a proof of concept.
Also in my experience the performance isn't great. In fact it was kinda slow, though I haven't had a chance to switch it to use a shared dataset, which I suspect would help a bit. Please let me know if you find a better solution.
I have not found a way to do this completely dynamically. Here is a similar question with some possible solutions:
How do i represent an unknown number of columns in SSRS?
You basically need to create a 'master dataset' from the other Datasets that are based on your multitude of SQL scripts first.The master dataset should contain the data to be presented in it's most simplistic form, i.e. in a simple list format.
Finally, go to the toolbar in SSRS and drag a 'Matrix' into the report. A Matrix table acts similar to a pivot table in Excel or a CrossTab query in Access that will display whatever's in the Dataset.
