I have a VS 2010 Report, and I would like to pass values that are calculated inside of one .rdlc report to another. Can I somehow use the Parameters to send data back out of the report, or have some "return" value from the .RDLC?
I don't think you can have return values with report services.
Instead, assuming that the two report have different dataset, the only solution I come out so far is to include two dataset in your second report and recalculate your field.
Doing that, you can use your normal expression to calculate the values that you need from the first report specifying the first dataset.
Here really simple example:
Report 1
The report is using only the DataSet1
=Fields!AField.Value
Report 2
The report is using two dataset: DataSet1 and DataSet2
=(Fileds!AField.Value, "DataSet1") + (Fields!AnotherField.Value, "DataSet2")
Ofc the expressions could be more complex, but the most important thing is to specify the DataSet where the report have to take the filed.

I am working on a BIRT report. Its records are grouped on the basis of the status column. I was looking for an option in the Eclipse BIRT tool by which I can hide combinations of multiple columns in a row which are repeating. I have attached screenshots for both the current report and the expected report structure.
I tried the "suppress duplicate" option but that is limited to a single column. I am not able to apply this on multiple columns together. I couldn't figure out any other option. Please suggest any solution in the tool or do I need to change my query to return the result in the expected format?
Actual Result:
Expected Result:
There are three obvious ways to hide duplicate values.
All of these require you to configure this per column (BTW I don't understand why you consider this to be a problem).
As you already did: Use "suppress duplicates" at the column level.
Add more groups to your table after the existing group.
E.g. one group for the first column (whatever that is).
Then you can choose "Drop" "detail" in the properties of the corresponding group header cell. It's a bit difficult to get the layout right this way.
In your data set, if it's SQL, you can use a little construnct with CASE and the LAG analytic function to compare the column value to that of the previous row, and if they are equal, return NULL instead (pure SQL solution).
I have an Oracle 6i report with Two Complex Queries (Q1 and Q2) connected by Data Link. The report was developed by some other developer who is not available now. Multiple columns are being displayed in report.
Q1 has a column Total_Issuance and Q2 has a column Total_Consumption. I have to display their difference on report. I am using a formula column to get the difference and then binding a display field to this formula column to show on report.
But since the formula column is outside both the queries, I am getting following errors.
REP-1517: Coloumn 'CF_1' references column 'Total_Issuance', which has incompatible frequency.
REP-1517: Coloumn 'CF_1' references column 'Total_Consumption', which has incompatible frequency.
Just like the formula column is outside both queries, create two additional summary columns (outside of both queries):
cs_tot_iss, which will sum total_issuance
cs_tot_con, which will sum total_consumption
Now modify formula column so that its source are newly created summary columns, e.g. let it
return :cs_tot_iss + :cs_tot_con;
As of paper layout: you don't have to display cs_tot_iss nor cs_tot_con (as you already have those values via total_issuance and total_consumption), just add formula column.
Create a new calculated field to the query that is the detail query (I asume it's Q2).
In this calculated field you can simply use:
return :Total_Issuance - :Total_Consumption;
to calculate the difference.
I have been battling this issue for days without success. I have a very tricky format of a report i need to achieve but the main thing is that all the datasets will need to be grouped by 1 parent. I'll attempt to explain...
Say we have dataset1, dataset2. Both have AccountNumber as common field(parent).
I need both datasets to be used in the format/layout of the report but grouped together by AccountNumber, something like this.
[Report Header Data]
[AccountNumber Group]
Dataset1
Dataset2
[end AccountNumber Group]
What is the best way to achieve this? The format of the report has been a major road block on grouping thus making me split the data into multiple datasets, group all them together by accountnumber and then create a custom format per dataset in the report. The flow of the report may be something like this
[Report Header Data]
[AccountNumber Group]
[tablix1]
Dataset1
[tablix1]
[tablix2]
Dataset2
[tablix2]
[end AccountNumber Group]
Looking forward to the discussion on this!
There are multiple ways to achieve this effect, and the best for your situation depends on the details of your report. So I'll just give some of the techniques I've used in the past:
Join the two datasets into one
Joining the datasets into one in your query is one of the simplest answers, and works across all versions of SSRS. It can make the SQL queries large, but it makes report layout simple.
Use the Lookup(...) function
SSRS 2008R2 added the Lookup(...) function, which can be used to access items in a second dataset. It's a little bit awkward to use, and requires a separate formula for every field to be accessed, but it is very powerful for retrieving a few fields from a different dataset.
Sub reports
Similar to the approach descibed in the original question, This lets you create a parent project with one tablix, and then place a subreport within. The subreport will be called multiple times, with the Grouping item as a parameter. Each run of the report should only return the report for that instance of the group. This can be very powerful, but maintenance is difficult: you have two places to change some thingss, and it can require manual tweaking to make sure columns line up correctly. The subreport will often be the fastest report to run, since it is getting called many times.

I don't know if there's a perfect solution here.
Based on your description, (and it sounds like you're leaning in this direction already) you'll need a Dataset for each distinct AccountNumber, and create a new list or table based on this.
Once you have this set up you need to embed the different Dataset objects (i.e. tablix1, tablix2) in each row.
The main issue here is that you can't use multiple Datasets when embedding tablixes within tablixes, so this makes me think that you may need a subreport solution - this way the subreports can take an AccountNumber parameter and each use a different Dataset.
So something like:
[Report Header Data]
[AccountNumber Group]
[subreport1]
[tablix1]
Dataset1
[tablix1]
[subreport1]
[subreport2]
[tablix2]
Dataset2
[tablix2]
[subreport2]
[end AccountNumber Group]
This will repeat for each AccountNumber as required.
It's tough to say without knowing exactly what your data looks like, but in 2008R2 and above you can use Lookup and LookupSet to join Datasets, but that will be cumbersome for multiple values, even if you are running the correct edition.
Again, depending on your data, another option is adjacent groups, if you can manage to get the data in one Dataset... This would allow to have different groupings next to another under the AccountName group, but it's a long shot.
It would be great if we know the report data e.g Payslip, payslip with loan balance (ie Dataset 1 for payslip and Dataset 2 for loan).
Anyway, the format will depend on the required output of the report. i.e If your planning on produce calculation like sum in the report and if the result output will be per Dataset or for both dataset.
Assuming you will need sum calculations, if the calculation result will be per dataset, then option 2 is good, if the calculation result is for total (Dataset 1 + Dataset 2) then option 1 is better.
If no calculations or total result is required, either will do.
I have several DataSets in an SSRS report. How can I use a summed matrix (crosstab) column from one DataSet in a formula of another DataSet with the same data fields (just different selection criteria (categories differ)). When I specify that field in the other DataSet, it only gives me First every time (I did not use First()); it does not automatically move them with the crosstabs in the second DataSet.
You cannot do this in SSRS 2008. This capability is first available in SSRS 2008 R2. Depending on how you use the data in the report layout, you might be able to use the ReportItems collection to get a value. For example, you can use the contents of Textbox1 with a field in a different dataset (field called MyColumn1) in an expression like this:
=ReportItems!Textbox1.Value + Fields!MyColumn1.Value
The ReportItems collection uses the value of a textbox after the page is rendered, so you get the result only and not the raw data so you'd have to be using raw data.
This is my first attempt to create a Visual Studio 2008 report using parameters. I have created the dataset and the report. If I run it with a hard-coded filter on a column the report runs fine. When I change the filter to '?' I keep getting this error:
No overload for method 'Fill' takes '1' argument
Obviously I am missing some way to connect the parameter on the dataset to a report parameter. I have defined a report parameter using the Report/Report Parameter screen. But how does that report parameter get tied to the dataset table parameter? Is there a special naming convention for the parameter?
I have Googled this a half dozen times and read the msdn documentation but the examples all seem to use a different approach (like creating a SQL query rather then a table based dataset) or entering the parameter name as "=Parameters!name.value" but I can't figure out where to do that. One msdn example suggestted I needed to create some C# code using a SetParameters() method to make the connection. Is that how it is done?
If anyone can recommend a good walk-through I'd appreciate it.
Edit:
After more reading it appears I don't need report parameters at all. I am simply trying to add a parameter to the database query. So I would create a text box on the form, get the user's input, then apply that parameter programmatically to the fill() argument list. The report parameter on the other hand is an ad-hoc value generally entered by a user that you want to appear on the report. But there is no relationship between report parameters and query/dataset parameters. Is that correct?
My last assumption appears to be correct. After 30 years in the industry my bias is to assume a report parameter actually filters the SQL data using the given parameter. This is not the case with .rdlc files used by Report Viewer. These report parameters have nothing to do with fetching data. Sounds like this was a design decision on Microsoft's part to completely separate the display of data from the fetching of data, hence, Report Viewer has no knowledge of how data may be fetched. Best way for me to conceptualize this dichotomy is to think of Report Parameters more as Report Labels, quite distinct from the dataset query parameters.
