Report Viewer and Multiple Data Sources

I know that it is possible to create a report in Crystal Reports using multiple data sources. But is it possible to use just the Free Report Viewer to view a report with Multiple Data Sources?
Our company uses Crystal Reports XI. I do not use the program myself, I am in the IT Department. I have limited knowledge of Crystal and do not do any of the report writing.
If this is possible, and if someone could help me out with what would need to be done, or point me in the right direction of a Knowledge Base or Help Topic that explains this, that would be great.
Thanks.

I believe it can but both data sources need to be set up. Ask a report designer to help you use the Designer to test this and see what is required.

Report Viewer and September Dates

We're experiencing a very strange bug with the report viewer. On date prompts, if the month of September is selected from the drop down calender, the inputted value is for October. So even if I select September 1st from the calendar, it becomes October 1st.
Can anyone else duplicate this?

Hi Scott,
Can you please let me know what type of parameter you are using? static or dynamic?
If static you might be created the parameter like this
value= 1,2,3,4,5,6,......
Description=Jan,Feb,......
If so please check the value for SEP.
If I understood wrong please let explain in brief.

Crystal Reports 2008 and Excel data source

I want to use a large Excel-sheet (with 139569 lines) as a data source for a report. Crystal Reports 2008 only seems to accept Excel sheets as a data source if they are stored in Excel 97-2003 format. But, then there is a limit of 65536 lines and I miss more than half of the data I need to process. Does anyone have an idea how I can solve this problem??

Hello,
No work around in CR when connecting to xls files. CR can only use xls files which has the 65K row limit. Our next version does support xlxs files though. Cr for VS 2010 is available, no Designer outside of the IDE though. CR 2011 is still in beta and no release data announced yet.
For now all you can do is limit your sheets to 65k or export your XLS files to Access, must also be an MDB file type, not the new extended type. Once in an Access database now you can use it as your data sources.
You can use a temp database so it gets destroyed each time or simple delete all records. Up to you how to manage it.
Thank you

Increase performance in a multiple data source report

Post Author: ArturoFromPeru
CA Forum: General
Hi everybody.
I have a big problem, when i make a report that have multiple data sources the performance decrease considerably, i still don't know the reason. Is it true that using multiple data sources is too slow?.
I tell you a fact: I made the report connecting via "Field Definition File", and it take at least 2 minutes to show itself but it only have 170 records, and i'm very sure that the sql statements to each data source were executed very faster.
I even heard about index, but i think they only are useful when i connect directly to the database.
All my partner told me, that Cristal Report
Thanks you in advance

Thanks you, but I explain better what i was doing.
I've made a report called "Kardex de Producto" which show the behavior of the products according to its sales, purchases.
The end result which is showed by the report is correct. I used three data source in the report, so links between each table is correct. The only problem i have is the performance because i still don't know why is too slow. In fact the sql statement is very heavy, but i think it doesn't matter to the report because when it takes the data from the database (connecting via Field Definition File) even if the very heavy sql statement returns twenty record Cristal Report must show itself very quickly. I don't want to believe that Cristal Report is very slow when it works with multiple data sources.
Do you mind if i give you my report? if not please leave me your email address.

BI+ Reporting With Multiple Data Sources

Hi -
We've been using BI+ Reports with multiple data sources on separate grids. We are wondering if there is a better way to ensure the user has their point of view bar in sync between the the data sources. In our case, both Data Sources are separate HFM applications with all the dimensions identical except the account which is defined on the report. We are not using Metadata Management.
I'm aware of the "Merge Equivalent Prompts" in the Preferences > Financial Reporting window, but this does not always ensure the users have the same point of view.
What practice are other companies using to make sure the user runs the reports accurately with both point of view bars pulling the same entity/year/period.
Thanks in advance.

Thanks for your answer, however my question - I know it looks quite messy - is not directly related to data templates, my problem is that at the moment I am using a stored procedure following - almost exactly - what another procedure does in oracle EBS to call a BI publisher report.
1. This procedure populates some temporary table with the xml data where the concurrent request picks it up and uses it to populate the BI publisher template.
2. However I can't go and specify the XML location in my data template as this is not an option for us (i.e. reading the xml from the temporary table), so I am looking for another way to populate the BI publisher template (Note: I can't as well include the SQL queries in my Data template).
Thanks ;)

Can we combine multiple data sources in single report?

<span style="font-size: 10pt; font-family: Verdana">Can we combine multiple data sources in single report?</span>

If you can't do this at the Metalayer (BVs or Universe) - then subreports and shared variables are the method for CR to use multiple datasources in the same report.

Report model to have multiple data sources

Hi,
We have requirement to develop report model in 2008 having multiple data sources which includes SQL SERVER 2012 and Oracle database so end user can all the relevant data in one place to run in report builder. So please advise how this can be achieved.
One option I can think of pulling all the data into one database through SSIS and then build a smdl on it.
I heard it might be possible to build Tabular cube and then use Report builder on it not sure which is the best option unless any other solution.
Thanks,

There are multiple options
1. If its just for need of a single report then you don't necessarily need to use SSIS and bring all data to single database for that. SSRS supports multiple heterogeneous datasources so you can simply create multiple datasources one fro SQLServer and one
for Oracle. Then you can create datasets based on these datasources and use them inside reports to display the data from the two systems.
One thing to note here is that SSRS provides only limited capability to merge fields from multiple datasets within same container through the use of Lookup, LookupSet etc functions so if you want to do lots of comparison ,manipulation of fields against two
datasources then you need to go for common database approach itself. This involves building a datawarehouse/datamart which will assmeble data from various sources and change them into format which report expects. Then its just a matter of using single
datasource pointing to this common repository for your reports.

OBIEE report with HFM and Essbase Data source

Hi All,
Just want your though can we get the data from HFM and Essbase data source in a single report i.e. for some account i want to show budget data from HFM and Forecast data from essbase in a single OBIEE report? If yes how can we model both Data source in rpd?

It possible but the challenge is to try to align the account hierarchy and the entity hierarchy between Essbase and HFM. HFM is looking the data at a top side consolidation level where planning will have more granular details to forecast correctly. The best solution is either to build a custom table in to import both sources, or to use HFM data into Essbase, or to use EPMA. The best in class solution stays to align hierarchies and metadata across applications. We implemented BI Financials Dashboard for the General Ledger, built a custom Dashboard connected in Real Time to Planning and are installing OFMA to connect HFM. Once done, you can rationalize metadata if not done before and start to link the different data into single reports. You will also have to ensure the data is refreshed at the same time to avoid inconsistency.

Regarding Creation of Views and Multiple Datasources.

Dear All,
I hv a COreport(Cost Center Report).the data is coming from tables of CO,FI,SD,MM.
The Tables from CO are COEP,COSP,COSS,CSKS,CRHD,CSKU,CRCO,CSKB
The tables from SD are VBRK,KNA1
The Tables from MM are EKKO,LFA1.
The table from FI are SKAT,BKPF,BSIK,BSAK.
1)Can i create a view for these tables?Can a view be called a DS.
2)With these tables i hv Multiple DS's.So can i use Multiple DS's to extract data
3)Can i use FM to extract Data?If i use FM,vll i face errors during Support?
4)Please Guide me how to create Views for these tables and How to handle Multiple Datasources.
Thanks

Noor,
Have you checked suitable business content datasources.
I think you have lot of options
FIrst You need to have a multiple data source
--> Check for suitable business content datasources
--> check whether these details are already available in BW through any means (through other standard datasources to ODS)
--> Create customized extractor finally as a last option
All these tables are atandard and nost probably you would find a standard datasource ( again multiple) I am sure for costing you have standard
Few or more standard datasources or already existing BW objexts with 1 or 2(rarely) customized extractor would do the purpose that you look for,....
Good Luck !!!

Any examples of a data template using multiple data sources?

I'm looking for an example report using multiple data sources. I've seen one where they do a master/detail but I'm just looking to combine results in sorted order (sorted across all data sources). The master/detail used a bind variable to link the two defined queries, I'm thinking what I want won't have that, so I'm lost on how to make that happen. I have reports using multiple sql queries and there is a way in the data source pulldown to tell it to combine the data sources. It appears to be a more manual process with data templates, if it's even possible.
Any pointers/links would be appreciated.
Gaff

Hi Vetsrini :
That's just it. Mine is simpler than that. There is no master/detail relationship between the two queries. I have the same exact query that I run in two databases and I want to merge the results (ordered, by, say eventTime) in one report. So I think my results are going to be two separate groups (one for each data source) which I'll have to let BI merge vis XSLT or whatever it uses. That's fine for small result sets but for larger ones, it would be nice if the database did the sorting/merging.

How to develop a report based on multiple data bases in BIP

Hi,
I have to develop a report based on multiple database(Sources). My queries is having multiple data base tables. How to achieve this in BIP
Regards,
Malli

Hi ,
After creating the dataset under datamodel save your data sets.
Click on Datamodel , on the right side window you will have the Main data set option , click on the drop down option and select Concatenated sql option.
Check the below links you will get a good idea.

Multiple Data Sources In One Logical Table

I am new to OBIEE and I have came accross an issue. I appologize if this information is in the forum somewhere but I have searched and cannot find it.
My situation is that I would like to have one logical table that contains multiple data sources which have all the same columns. I already have session variables setup to differentiate the user's security through a row-wise variable for a specific column and a session variable for another column which determines the user's association to the data source in which they belong to. This security works well when the data sources are seperated in the Business Model and Mapping portion but the issue that arises is that the user's cannot share reports when the data sources are seperated in the BM&M.
I have dragged and dropped a table from the Physical model to the BM&M, I then dragged the second data source (with same meta data structure) over to the "Sources" folder in the first data source table in the BM&M. On the Content tab or each data source table I have defined the WHERE clause as such, where VALUEOF(NQ_SESSION."SCHOOL") session variable is my row-wise column filter and the VALUEOF(NQ_SESSION."GROUP") filter is my data source determinative:
sandbox."".SANDBOX.OBIEE_CROSS_ENROLLMENTS.HOME_SCHOOL = VALUEOF(NQ_SESSION."SCHOOL") AND sandbox."".SANDBOX.OBIEE_CROSS_ENROLLMENTS.DATA_SOURCE = VALUEOF(NQ_SESSION."GROUP")
Unfortunatley this only returns values in the BI Answers for the first drag and drop Pysical table in the BM&M layer and not the second Physical table drug into the "Sources" folder. I have also tried to create a new logical table and drag both tables into the "Sources" folder to no avail. I have experimented with the Fragmentation content on the "Content" tab of the seperate logical tables, checking the "This source should be combined with other sources at this level", which gives me an error in BI Answers that a column does not exist which really does.
What could I be missing? Advanced thanks to those who reply.
Thank you,
Kyle

Stijn,
Thank you for the article link. That was very helpful! It seems that I had a few things off as you do need the "This source should be combined with other sources at this level." checked. In my two table source columns for DATA_SOURCE I defined a literal ('086496' and '085597' for the other) in the Column Mapping tab. I pasted the following in the Fragmentation content, checking the "This source..." box on the Content tab:
eSIS.SANDBOX4_SCHOOLS.DATA_SOURCE = '086496'
And pasted the following into the WHERE clause, checking "Select distinct values" on the Content tab:
sandbox4."".OBIEE.NWOCA_SCHOOLS.SCHOOL_CODE = VALUEOF(NQ_SESSION."SCHOOL") AND sandbox4."".OBIEE.NWOCA_SCHOOLS.DATA_SOURCE = VALUEOF(NQ_SESSION."GROUP")
This took care of my user's security, utilizing the session variables in the WHERE clause. I am now able to generate reports that only one user can access from one data source and share that same report with another user who can only see data from the other data source.
Many thanks!!!

Bursting with multiple data sources

Hello all,
I am working in a retail environment and we are building reports for the stores. There are several reports and they all receive the same reports. We are using BIP Entreprise with the bursting feature and it works very well.
The problem is that there are too many reports and we would like to combine all reports of the same store within the same PDF. We use the multiple data source feature and was able to concatenate all reports together.
Using this new report and template, we can not make the bursting functionality to work properly: the bursted report do not contain all the required report components.
For example, I have 2 queries A and B each producing reports for 3 stores: 2, 4 and 5. Without bursting, the output is as is:
Query A - Store 2
Query A - Store 4
Query A - Store 5
Query B - Store 2
Query B - Store 4
Query B - Store 5
With bursting into a file using the store number, I get the following:
File 1 - Store 2 - Query A
File 2 - Store 4 - Query A
File 3 - Store 5 - Query A
+ Store 2 - Query B
+ Store 4 - Query B
+ Store 5 - Query B
I would like to have the following output:
File 1 - Store 2 - Query A
+ Store 2 - Query B
File 2 - Store 4 - Query A
+ Store 4 - Query B
File 3 - Store 5 - Query A
+ Store 5 - Query B
The main question is: can this be done using BI Pub Enterprise? We using version 10.1.3.3.2
If it is, can you provide me with help on how to configure either/or the requests and template to accomplish this task?
I create an SR and Oracle Support does not have an answser and suggested that somebody in the Forum might help.
Thanks in advance,
Minh

I would like to have the following output:
File 1 - Store 2 - Query A + Store 2 - Query B
File 2 - Store 4 - Query A + Store 4 - Query B
File 3 - Store 5 - Query A + Store 5 - Query B
the bursting level should be give at
File 1 - Store 2 - Query A + Store 2 - Query B
so the tag in the xml has to be split by common to these three rows.
since the data is coming from the diff query, and the data is not going to be under single tag.
you cannot burst it using concatenated data source.
But you can do it, using the datatemplate, and link the query and get the data for each file under a single query,
select distinct store_name from all-stores
select * from query1 where store name = :store_name === 1st query
select * from query2 where store name = :store_name === 2nd query
define the datastructure the way you wanted,
the xml will contain something like this
<stores>
<store> </store> - for store 2
<store> </store> - for store 3
<store> </store> - for store 4
<store> </store> - for store 5
<stores>
now you can burst it at store level.

CFTransaction & Multiple data sources

We have the need to update to multiple data sources under
CFTransaction. We have two MSSQL databases so I was able to create
a view in one to the other and that works (unless someone knows of
a problem that could cause). But we also have a MSAccess db that
gets hit too under the same CFTransaction. CF does not allow you to
have multiple data sources under one CFTransaction. If all the
tranasction control is on the db side, why does CF care if there
are different data sources?
Thanks.

As I said in my original post, in order for a transaction to
span multiple databases, you need to do what's called "2-phase
commit" or "distributed transactions". This is not a trivial thing
to do, nor is it something that is often needed (especially in
Coldfusion, which is 99% of the time talking to a single database).
Why do you need to do 2-phase commit? and why isn't it
trivial?
"2PC is an acronym for 2 Phase Commit. This is a protocol by
which data being committed to a database is committed in two
phases. In the first phase, the transaction processor checks that
all parts of the transaction can be committed. In the second phase,
all parts of the transaction are committed. If any part of the
transaction indicates in the first phase that it cannot be
committed, the second phase does not occur. ODBC does not support
two-phase commits."
http://docs.openlinksw.com/virtuoso/twopcimplementation.html
I don't think Access supports 2-phase commit. Access isn't
really intended for the kinds of things that need 2-phase commit,
which Microsoft readily admits (hence MS SQL Server).
> My thought is that it is not allowed because CF only
remembers one data source per cftransaction therefore can only send
one commit or rollback instruction. If that's the case, it sounds
like a simple enhancement.
No, this isn't allowed because distributed transactions is a
non-trivial thing. This isn't all handled on the database side, as
you reference. If you're dealing with one datasource, yes, it does.
Once you pull in a 2nd datasource, you need something that can talk
to all databases involved (a transaction coordinator) and 1) check
to make sure everything can be committed safely then 2) commit
everything (hence 2-phase commit).
Basically, you're trying to do something that's non-trivial,
you don't understand why it's non-trivial, so you're getting
frustrated. I realize you're not a Java shop. I was simply trying
to explain to you why it was non-trivial, and a method to work
around that if you so desire.

You can use SSIS to collect data from multiple sources (SQL Server, Oracle, etc.) and store it in SQL Server database. Then you can use SSAS to build a cube on that database. With SSRS/reportbuilder you can create reports on the cube or on the database...
