I am new to COGNOS. I have few queries in my COGNOS already created by someone and a report is generated based on this. Some error occurred to the cube for this report and I do not have access to cube. Now I need to alter the columns and manually generate a report for the client for time being until cube is ready. But I do not know how to access the column of a table in Cognos when I have access to queries and reports. Please help to resolve. Thanks in advance....
I am trying to create a SSRS report with sql server 2005 BI. I have to use the existing data source to be consistent with the other reports, but in the SharedDataSources folder when I click add existing item, I cant find the Data source.
Can someone tell me where the Data Sources for SSRS reports store physically on a machine?
Thanks
It should be stored in the SSRS project. It will appear as .rds file.
I am a newbie in Cognos. I am trying to create a report using report studio, I have the required package, and I want to create a report using a complex SQL query which has joins between three tables. Can anyone please give a suggestion to start building the report? Thanks!
How to write SQL for Cognos reports
FM is to create complex models. If you need a quick-and-dirty report you can specify custom SQL as the tutorial shows.
It would depend on how the data you see in Report Studio is modelled, typically a tool called Framework Manager is used connect to and model the source tables and views. Framework Manager creates the packages that you see in Report Studio, it can define relationships between entities like tables (if they're not already defined in the source database).
Not sure how to tell from Report Studio if the relationship has been defined properly other than trying to pull over fields from each table into the same Report Studio Query. It is best to talk to whoever designed the Framework Manager model or look at the model itself.
I am developing a reporting application where a user can select(and order) reports from a list of 100 reports and ask for a master report. This master report will contain all the selected reports in the exact order and with a table of contents listing the reports included in the master report. The reports available for the user to select (which could be 100s) are stored in the database.
My questions are :-
To generate the master report with the user selected reports, the only solution I can see is using the Reporting Engine API to generate a dynamic report into which I have to add the user selected reports as subreports. Is this the right and easiest way to approach this problem? Does anyone have samples of the Reporting Engine API usage especially to inject subreports in a Master report?
Since I am storing the reports in the db(blobs), I am trying to find a way to generate my sub reports with an inputstream rather than a URL as specified in ResourceManager.createDirectly(url, MasterReport.class), but haven't been successful till now. How can I generate reports from definitions stored in the database? There should be some resource abstraction.
Read your reports into a byte-array and then use the ResourceManager.createDirectly method as usual. That will solve your problem of parsing the reports.
You can parse them directly into SubReports by using
ResourceManager.createDirectly(bytes, SubReport.class)
These subreports can then be added to your master report as banded subreports. if you want your selected reports to start on a new page, make sure you set the "pagebreak-before" style on your subreport's report-header.
There is a resource abstraction: It is called "LibLoader" and you can create your own ResourceLoaders that deal with the problem of getting your data out of your database as raw-streams so that the ResourceFactory implementations can interpret/parse the raw-data.
But every database is designed differently and thus you as the system integrator have to write the glue code for it. We only can offer the interfaces.
I am using RDLC Reports and the report viewer control, and I am seeing that the more records there is in the final result the longer it takes to load.
It sounds to me that the RDLC report loads all records at once (and caches them locally) even though it paginates it when sending to the browser.
So I believe the solution should be to cause the report to load only the records needed for the current page.
How can I do this?
Or if there is another solution to optimize then please let me know
If you need to analyze and aggregate a huge amount of records (millions) you can do the work on sql server using a Stored Procedure or a Query and next you can output to the report viewer only the aggregated data.
This is useful when you don't need to show the details of your data in your report.
