Crystal Reports with Graphical Linking on Multiple Data source

Hello
I have a report which uses graphical linking on 6 tables/views which acts as the data source.
4 are on HANA and 2 on a legacy system.
Record selection filters are applied to filter data.
Report's performance is incredibly slow on running for higher date ranges even for less than a month bringing back < 10000 records.
Please suggest any tips to improve this.
already tried below :
Checked no printer option
Removed Page N of M control
Changed Order links to pick small tables first
Crystal Reports 2013 connecting via ODBC to HANA and legacy
-Jayakrishnan

Hi Jayakrishnan,
When you join tables from multiple datasources, CR processes the joins and any record selection criteria locally. This is what slows down the report.
The only way to speed up performance is to have all the data atleast come from the same database or even better, creating a view that has all the required tables and joins.

Crystal Reports Developer Edition XML or Java data source

<p>Is there a way to use XML or custom Java objects (POJO) data source in Crystal Reports Developer Edition ? Currently Crystal Reports is being invoked as API from an existing code. But that code can be modified if need be.</p>

Hello Jayashree,
please see a sample for CR 08 with XML as datasource [here|https://smpdl.sap-ag.de/~sapidp/012002523100006016532008E/XML_datasource.zip].

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.

Report Designer odbc connection string for data source using a parameter

I am using stand alone report designer 3 for the present and have a question/problem regarding the odbc connection string for MySQL when setting up the data-source
I need to be able to enter a parameter which is the database name i.e. BOE-201401 or say BOE-201312 etc from a list of databases the user can choose from.
at present the odbc connection string points to BOE-201402
the connection string is at present Dsn=Development Server for MYsql;description=MYSQL;server=ldndw01;database=BOE-201402;port=3306
my parameter has the name BOE_DATABASE
and in an expression it is as such
=Parameters!BOE_DATABASE.Value
I want to point the datasource for the report to the parameter value before the user sees the report.

Hi Leslie,
Based on your description, we want to design a report with a dynamic DataSource connection string. There are the basic steps below for your reference:
Create report with static database.
Change data source to report parameter.
Send new database connection string as a report parameter.
More detail information, please refer to the following blog: Dynamic Database in SSRS 2008.

Crystal Report with text(csv) data file, can we set it as input parameter?

Hi,
I am a new user of Crystal Reports 2008.
I have created a report with charts in it. The input data comes from a csv text file.
Can I set the name of this text file as an input parameter?
as I need to generate 44 similar reports with different text filenames(and data)?
Thank you.
Regards

Brian,
Thanks much.
I did exactly what you said.
Just to see any change, I first gave a bad report file name just to see if I am accidentally pointing to a different file,
but I got an error saying report not found.
Then I renamed my original datafile name and generated a report and it still generated one without giving an error.
Then I also gave a junk name to the logoninfo and printed that name, the new name was assigned to logoninfo, but the code did not error out.
It ended up generating the report.
Now here is what I think is happening,
1) The save data in report option seems to be still on even though I have turned it off in 2 locations
a) file -> Report Options
b) file -> Options -> Reporting tab.
2) For some reason the logoninfo is getting ignored as well.
Since I did not see any answers yesterday I posted a link to this thread on the .Net forum
Crystal Report with text(csv) data file, can we set it as input param? C#
and Ludek Uher says that I am connecting to the text file via a DAO database engine and so need to use the same code for changing the text file as for changing an Access database.
But the link he gave me tells me to try the same thing that we have been trying..
Here is my plan,
1) I will first try and find out why my save data with report option is still on ( but it shows off in Crystal ).
2) why is LogonInfo getting ignored.
Meanwhile any suggestions from anyone are welcome.

Crystal Report with text(csv) data file, can we set it as input param? C#

Hi,
I am new to the forums and posted a question which belonged to the .net - SAP Crystal reports group.
Can someone help me with my problem? following is the thread that I have started.
Crystal Report with text(csv) data file, can we set it as input parameter?
Thank you in advance.

Looking at the original thread, you are connecting to the text file via the DAO database engine:
"I added the text file as follow, new connection -> Access/Excell (DAO) -> select the file and the database type as text"
Thus I would use the same code for changing the text file as for changing an Access database. See Kbase [1218178 - Error: "Logon failed" when connecting to Access database in .NET application|http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes_boj/sdn_oss_boj_bi/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes%7B6163636573733d36393736354636443646363436353344333933393338323636393736354637333631373036453646373436353733354636453735364436323635373233443330333033303331333233313338333133373338%7D.do] for more information. If that does not work, you may want to consider connecting via ODBC or feeding the data from the text file to and ADO .NET dataset and pointing the report at the dataset.

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 ;)

Connect Crystal report with FI Data through MAXDB ERP Tables or Datasources

Hi,
I want to create crystal report queries for SAP ERP FI Data. The source system database is MAXDB.
How can i connect the maxDB database or ERP to crystal report?
Do i need tables or datasources to create queries, and how do i connect them to crystal report.
I will thankful for any help.
Kind regards
Arnaud

I would recommend to take a look here:
BOBJ and SAP R/3
/people/ingo.hilgefort/blog/2008/03/23/businessobjects-and-sap-part-4
The drivers I am talking about will be available in the CR Designer once you install the BO integration kit for SAP solutions.
If you try to access directly the underlying MAX DB database you will not have access to all data since SAP ERP stores the data partially compressed in the database tables.

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.

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.

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.

Crystal Reports with BEx Query using Custom Exit Variable

Hi,
We have BW BEx Query using Customer User Exit variable to derive the Fiscal Week for Last Year (called it VAR2) based on another user input variable Current Fiscal Week (called it VAR1).
VAR2 is derived from VAR1 in CMOD via some codings and thus it DOES NOT have the "Variable is Ready for Input" flag ticked in the BEx. VAR1 is user input variable, so it has "Variable is Ready for Input" flag ticked in the BEx.
When we create a Crystal Reports with the BEx Query using variable VAR2, and when we run it we got an error message saying "Failed to execute query; '[]<java.lang.UnsupportedOperationException: No Selection State Support!ZP_MI_LYPUBWEEK>'. Redesign your query or contact the data source maintainer to solve the problem". (note: ZP_MI_LYPUBWEEK is VAR2 in this case).
Could anyone please assist? Surely, CR supports BEx customer user exit variables like the above, right?. I also refer to the forum below as it seems to have a similar issue (except mine with an error message), but it does not provide a solution in it.

Hi Vibhav,
We have the SAP Crystal Reports for Enterprise XI4.0 Version 14.0.0. Not sure if SP0 or other SP, got to check with Basis Team later.
We tried that "mandatory" option and did not work either.
Anyway, SAP has now come back again saying it is something they will fix it in next release/version. We got a phone call from them and a reply below to our OSS.
23.08.2011 - 08:20:49 CET - Info for Customer by SAP
I have raised this issue on the Idea#s Place as an enhancement request
on the below link:
https://cw.sdn.sap.com/cw/ideas/5586
This ER contains the information of including the customer exit
variables in the report without checking the #input for ready# option.
This ER can be considered for being implemented in the future
versions. You can refer to SAP Note: 1515837 - How To: Enhancement
