Universe Design with same connection

Hello,
I am creating universe against the connection for SAP BW system, once I have created a connection and selected a cube or query and built a universe on top of it....If I go back and create a new universe and this time change the connection to point towards a new cube/query the old universe stops working.
Is it a limitation for SAP database where we need to have a new connection setup for each universe...or is there a different way to use same connection pointing towards different cubes/queries for different universes.
Please let me know.
Thanks
Dharma.

Hi,
Currently, you have to define one connection per BEx query. If you want to uset a different then you have to update the connection and refresh the universe to take injto account potential changes.
Normally, it is possible to override a connection to point to a different cube using security. It means that you can give access to a given query for a group of users and access to another query for another group of users.

Didier

Hi
when you build a universe based on the connection and want to use the universe with reports you can not change the underlying connection because then your universe will not work anymore.
You can have multiple universe on a single connection.
here some more details:

Issues with changing connection at run-time

Post Author: dmazourick
CA Forum: Data Connectivity and SQL
Weu2019ve tried a lot of different ways to resolve this issue, but are getting every time the different result.
Probably someone deal with that issue before and know how to correctly resolve it.
Weu2019re using Crystal Reports Runtime Components X+ (X, XI, XI R2) u2013 all of them has this issue.
We need client application to connect to multiple data sources u2013 user chooses report, chooses data source and we show the report for specified data source.
The data sources are tables or stored procedures stored in different databases on different servers.
For sure, every data source for a single report has the same structure, but that doesnu2019t matter.
The issue is: when the name of the database on one server is the same as the name of database on second server, the connection caching occurs.
How we can check that:
1.       Weu2019re running report for Server1:<DBN> - report shows data from Server1.
2.       Weu2019re opening second report for Server2:<DBN> - report shows data from Server1.
3.       Weu2019re closing application and run 1-2 in opposite order, now both reports show data from Server2.
Weu2019ve tried different approaches u2013 below is a code sample that opens the report for specific connection.
Juts to be sure that no one will ask u2013 u201CAre you sure youu2019re passing the correct connection info etc.u201D. Yes! We are sure because weu2019re trying to fix this issue for a long time and tried a lot of different approaches and still cannot find the right solution.
The code looks like below. This is VB6 code, but also the same situation was tried on VC++ 6.0
Weu2019re not looking into CR.NET solution for now.
=================================================
Sub DisplayReport(Server as String, DB as String, UID as String, PWD as String, viewer as Object)
    Dim app As New CRAXDRT.Application
    Dim report As CRAXDRT.report
    Dim database As CRAXDRT.database
    Dim table As CRAXDRT.DatabaseTable
    Dim par As CRAXDRT.ParameterFieldDefinition
    Set report = app.OpenReport("D:\TestReport_X.rpt")
    report.database.LogOnServer "pdssql.dll", Server, DB, UID, PWD
    Set table = report.database.Tables(1)
    table.SetLogOnInfo Server, DB, UID, PWD
    table.Location = table.Name
    report.database.Verify
    viewer.ReportSource = report
    viewer.ViewReport
end sub
=================================================
The result of above code is the following:
1.       If we will pass the same viewer and will use different Server u2013 the report will be displayed correctly
2.       If we will pass different viewers and will use different Server u2013 the reports will contain same data
The result of above code also depends from the version of Crystal Reports the report was designed in:
1.       For Report designed in 8.5 u2013 passing of the same viewer with same connection info second time will refresh report
2.       For Report designed in X, XI, XI R2 u2013 no refresh
Also, a slight modification of the above code helps for reports designed in XI to work properly, but not for reports designed in X and 8.5:
1.       Before calling LogonServer, make the following: DB = DB & u201C;u201D & Int(rnd()*32767)
That makes report designed in XI to display properly in different viewers, but doesnu2019t have any impact to X and no any impact to 8.5
Weu2019re really looking for any help in this question

I am having similar problems and some successes.
I have 70+ reports and now suddenly I want to point them at two different servers, but at databases with the same name like you talked about.
I first just tried the following:
#1. Load report:
Dim myReport As New ReportDocument
myReport.Load(filename)
#2. Pass in parameter values
''Get the collection of parameters from the report
Dim crParameterFieldDefinitions As ParameterFieldDefinitions = r.DataDefinition.ParameterFields
''Access the specified parameter from the collection
Dim crParameter1 As ParameterFieldDefinition = crParameterFieldDefinitions.Item(ParamName)
''Get the current values from the parameter field. At this point
''there are zero values set.
'crParameter1Values = crParameter1.CurrentValues
''Set the current values for the parameter field
Dim crDiscrete1Value As New ParameterDiscreteValue
If crParameter1.ValueType = FieldValueType.DateField Or crParameter1.ValueType = FieldValueType.DateTimeField Then
If ParamValue Is System.DBNull.Value Then
crDiscrete1Value.Value = CDate("1/1/1900")
ElseIf ParamValue Is Nothing Then
crDiscrete1Value.Value = CDate("1/1/1900")

crDiscrete1Value.Value = ParamValue
End If

crDiscrete1Value.Value = ""
Else
crDiscrete1Value.Value = ParamValue
End If
ElseIf crParameter1.ValueType = FieldValueType.BooleanField Then
If ParamValue Is Nothing Then
crDiscrete1Value.Value = False
ElseIf ParamValue.ToString.ToUpper = "TRUE" Then
crDiscrete1Value.Value = True
Else
crDiscrete1Value.Value = False
End If
ElseIf crParameter1.ValueType = FieldValueType.NumberField Then
If ParamValue Is Nothing Then
crDiscrete1Value.Value = 0
Else
crDiscrete1Value.Value = ParamValue
End If
Else
If ParamValue Is System.DBNull.Value Then
crDiscrete1Value.Value = Nothing
ElseIf ParamValue Is Nothing Then
crDiscrete1Value.Value = Nothing
Else
crDiscrete1Value.Value = ParamValue
End If
End If
''Add the first current value for the parameter field
Dim crParameter1Values As New ParameterValues
crParameter1Values.Add(crDiscrete1Value)
''All current parameter values must be applied for the parameter field.
crParameter1.ApplyCurrentValues(crParameter1Values)
#3 Set "Table Log in info" (most of my reports using stored procedures, but I guess I still needed this step).
Dim CrTables As Tables = r.Database.Tables
Dim CrTable As Table
Dim crtableLogoninfos As New TableLogOnInfos()
Dim crtableLogoninfo As New TableLogOnInfo()
With crConnectionInfo
.ServerName = connectionParser.GetServerName(connectionString)

If connectionParser.DoesUseIntegratedSecurity(connectionString) = True Then
.IntegratedSecurity = True
Else

#4 go get the data
crv.ReportSource = myReport
crv.Refresh()
#5 Call export to disk function.
This was not changing server - did not realize it was a caching problem as you suggested. That makes sense. So anyway, then of course I threw a verify database statement on there, before I get the data. Now looks like this:
#1 Load Report
#2. Pass in parameter values (dummy values that will generate schema of table without having to actually run long running procedures, i.e. select (cast 1 as int) as somefield1, cast(2.0 as numeric(10,0)) as somefield2
#3 Set "Table Log in info"
#3b Verify the database which seems to be a necessity:
myReport.VerifyDatabase()
#3c Re-populate the report with real parameter values, same as #2 but this time with the ones that will generate the real data
#4 go get the data
#5 Call export to disk function.
This does work, some of the time. When the datasource underlying report are tables, it works. I made a dummy crystal report with lots of different types of params (stored procedure underlying database) - this also worked!
Unfortunately, when I run this against the majority of my reports, I get this stupid "invalid mapping type value", for which I have not been able to resolve yet.
I also tried putting a myreport.SetDatabaseLogon("","") -- what would this do, clear it out? (saw this referenced somewhere).
Then I tried putting the real connection info in there as well ...
myReport.SetDatabaseLogon(uid, pwd, serverName, DBname)
I put this setdatabase thing before I called verifydatabase, which is where the process is bombing out and giving me invalid mapping type for the reports that do not run.
At this point I am still working on solution. I have tried creating dummy report that used same parameter types as a report that was failing and voila - the dummy report worked. Anyway, let me know if you get your problem fixed and I will do the same. Looks like you are using a different method that I didn't notice "LogOnServer"

SSO does not work in Universe Designer

Hi,
I have a problem getting an error within Universe Designer the error is :
"DBD: Unable to connect to SAP BW server Incomplete logon data"
Installed below :
BOBJ XI 3.1 installed
SAP GUI 7.10
SAP Java Connector
SAP Integration Kit
All is run on the server machine.
SSO setup i CMS etc. and i works fine in the beginning and i can go into Universe Designer and create a SSO connection which responds etc. and i can create universes which is fine. I can go to webi and create an new report using the universe and select som measures and dimension and execute query, but it only works a couple of times then it starts to fails with an xml error. After that going to universe designer an into connection i cannot longer get in touch with my Bex query in SAP BW ! and that is where my problem allways ends, so now i cannot connect using SSO in Universe Designer.
Found technote 1250890 but it only says that i need to install integration kit on my client, but my installation is all i one and is installed.
Any suggestion would be much appreciated !

UNIVERSE DESIGN TOOL

Where can I find a sample database for practice to use in Business Objects Universe Design Tool and connect it to a server?

Thomas,
You still get sample UNV and database provided with BI 4.0 install is the eFashion.UNV, efashion.mdb (Access DB) and WebI reports. If you did a full install of BI 4.0, you can find the files in
C:\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\Samples\webi\
You also get so Island Resorts Marketing.unv & club.mdb.

Universe Design Best Practices for Oracle

Hello All,
We recently moved from XIR2 on MS SQL 2005 to XI 3.1 on Oracle. This has been a difficult move for us as my team is new to oracle. I'm currently working on several performance issues between BOBJ and Oracle and am looking for documentation on best practices for universe design with oracle. I've foudn tidbits here and there regrading using parameters joing_by_sql and boundary_weight_table, wondering if there are other options out there that might help. We have queries taking 45+ minutes to run and that is totally unacceptable.
thanks
Andrea

I am not sure if you are looking for Optimization or anything else. sorry for that following link might help you considering Oracle as DB.

URGENT: Connecting BPC 10.0 with BI4.0, with Universe Design Tool

Hi all,
I have quite an urgent question that I need some guidance from all you SAP gurus on!
Is it possible to connect BPC 10 to BI4 using Universe Design Tool? We are under the impression very few people have connected these pieces of software together, if at all. It is very important to a Project I am on at the moment as to whether it is possible so any advice would be very much appreciated.
So far we have done..
Software is installed - Universe Design Tool (UDT)
Logins have been created for BPC 10
Opened up UDT and go through the Wizard;
Connection name is BPC CCONNECTION
Select data access driver: Business Planning and Consolidation OLE DB for OLAP
Enter the server address for BPC 10 (This is the URL that we log in to the BPC Admin Console)
After we try to continue, we get the error as follows:
[Image of error|http://s9.postimage.org/pxk8raci7/UDT_Screen1.jpg]
If anyone could give any kind of advice I would really apprecaite it!
Nick

Hi Nick,
If you are trying to connect BPC 10 NW to BI 4.0 then I have some suggestions. We did this in our SAP EPM 10 training. In the Admin go to the model tab , select your model and edit it. Select the check box Use as a source. This creates a transient query in the backend.. Then we designed the connection in IDT (Information Design tool). Login to IDT and create a new project. Now Right click on the project and create a new OLAP connection. Select SAP BICS as driver selection. Provide the server details and user aunthetication. Select specify a cube in connection option. Now You can select your model <MODELNAME>_B folder and u will see one query with /CPMB/TQ_XXXX. Test your connection and publish your connection to repository . Now you can use this connection for creating Interactive Analysis (Webi Report). I am not sure about the reporting client you wish to use.
Hope this Helps

Problem with Database Connections in the designer - Catalog not updated

This is Crystal Reports 2008 (12.2.0290). We have a number of reports that are viewed using the .Net runtime with the connection details set at runtime using ODBC to talk to SQL Server on different systems. This all works fine and is not the problem. The problem is when editing reports in the designer take the following example:
Developer 1 creates report on their machine that references tables. DSN Name is DEV_DSN, pointing at their local database on their machine called DEV_DB1. Developer 2 needs to edit the report on their machine with a DSN of the same name (DEV_DSN) but this points to a different database on developer 2's machine called DEV_DB2.
Developer 2 goes to the Set Datasource Location option in the Database menu to get it to point at their local DB only it doesn't work. They click on the first table included (or the connection name) in the report and click update - they are prompted for the logon details for their local DSN/DB and supply them but they see an error indicating that there is an "Invalid object name" because the table is still being prefixed with the database name from developer 1's machine. When the table is expanded in this view the Catalog still shows as the DB name from developer 1's machine despite the connection properties above correctly showing the local DB name.
As I say this is a design time issue not a runtime issue.
Any ideas? Is there any way we can edit the Catalog name manually?

Try setting the Over ridden qualified Table Name
Set Datasource - > Tablename -> Properties
Double click Over ridden qualified Table Name, type name as shown in in the table name field above it.
Repeat for each table, this removes schema and db names associated with Table. Take a look at the SQL and make sure all tables are no longer prefixed.
Report should now be totally portable.

Baan with Universe Designer

Has anyone successfully built a Universe against a Baan database? We are looking at the possibility either using a Baan driver for Universe Designer (if this exists) or connecting to the Oracle system underneath.
Any help is much appreciated!
Thx
James

No idea but some things to check:
- Are you running some other application which might be using the Designer SDK on your machine?
- If you launch Designer and leave it there for 5 minutes without doing anything does the error comes up
--> some background agent might be interfering? Or is it triggered only if you actually work with Designer?
- What is the title of the popup window (Designer.exe or is it a Window system message error?)

Database Design for use with XSQL-connected Clients

Hi all,
this might seem a little off-topic at first, but I suppose we are not the only ones reading this group designing an architechture using XSQL servlet as the only connection to the database, with clients connecting over the internet.
So far our approach works well, but of course any database round trip is much more expensive in this environment than with clients that hold an open connection to the database.
That led us to the idea of generating primary keys on the client instead of the database (e.g. with CoCreateGuid on Win32). Do those GUIDs have to be stored in the Oracle database in a RAW column or does a NUMBER field do the job?
I found a hint in the Oracle 8i Replication manual to use SYS_GUID values in a RAW(32) column as a primary key to avoid conflicts between sequences on multiple machines. But I didn't find any statement concerning the performance issues of this.
Our database will not store huge amounts of data (most tables < 100.000 rows, just a handful more than a million in huge environments, which will be able to afford huge machines...), so this should not be
a problem, I guess.
Does anyone of you have experience with this?
And another question: Can I safely assume that keys generated with SYS_GUID on the Oracle server will not likely be the same as those that are generated using CoCreateGuid on the Win32 client?
Thanks for your input.
Olaf Lewitz
ohltec SOFTWERFT, Hamburg

Don't GUID's have hyphens in them? If so, you'd have to use a VARCHAR2(xx) of appropriate length. If not, then you can likely use HEX_TO_RAW() and RAW_TO_HEX() to store then in a RAW as you've noted.
Note that the XSQL Servlet's default connection manager does to connection pooling, so the roundtrip to the database may not be as expensive as you're thinking. :-)

Access Connections - Many APs with same SSID (Again)

I have a W520 running Access Connections 6.11 (release December 2013) on Windows 7 Pro 64-bit. Access Connections is still broken in regards to dealing with multiple Access Ponts having the same SSID. It keeps hoping from one access point to another regardless of signal strength of the AP.
The most desirable strategy would be if Access Connections would find and lock on to the best signal strength AP and stay there. However, it doesn't do that. It acts almost randomly. It also keep shifting around. The rate is almost random as well. Sometimes it will stay locked on to an AP for up to 10 minutes, at other times it shifts in as little as 30 seconds.
Other laptops, from other manufacturers like HP, Toshiba, and Apple do NOT exhibit this behavior on our campus. Other Lenovo machines running Access Connections DO exhibit this behavior. The problem is NOT machine specific (ie, not hardware or some weird idiosyncracy of the particular W520 i'm posting about). The problem is Lenovo's Access Connections. The problem is also not a configuration issue with the campus. I have a network at home running Airport Extremes all having the same SSID's and the W520 in question does exactly the same behavior there. Totally different hardware at home vs campus and same behavior. I cannot change the names of the AP as a fix. This is not a capability in the configuration of the AP's. Even if it were, I shouldn't have to do it. Campuses are often configured in this way. Campuses that are large commercial users who I believe are the most lucrative Lenovo customers.
This problem has been going on for literally years with different versions of Access Connections. Here are two threads in the Lenovo Community I found in under 30 seconds. Neither was solved correctly. In other words, Lenovo never fixed the software, and people had to either give up or resort to kludge solutions in their campus configurations.
http://forums.lenovo.com/t5/ThinkVantage-Technologies/Is-it-possible-to-default-to-a-specific-Access...
http://forums.lenovo.com/t5/ThinkVantage-Technologies/Access-Connections-Many-APs-with-same-SSID/m-p...
Lenovo has actually made the problem progressively worse over time instead of fixing it. They have done this by removing the abilty to prioritize AP's by MAC address. Initially, Lenovo allowed you to configure 5 MAC addresses in order. Then, Lenovo removed that capability making it possible to only give a single MAC address as preferred. Finally, in recent iterations, Lenovo removed that capability alltogether. The box is still there in the UI, but it's greyed out. It is very frustrating to have this kind of thing happen. The prioritize capability is fundamentally a kludge, but at least it's something to give a bit of a workaround. Now we don't even have that.
Can a lenovo engineer please look at this issue and give me a timeline for resolution?
BTW, It is still not possible to configure Access Connections with a blank SSID either. I bring this up, because if you're going to fix the Access Connections code for multiple SSID's, you should be aware of the blank SSID problem as well. I imagine they are both in the same part of the Access Connections codebase, at least from a logical standpoint.
Thank you.

I found that there is a setting in the Intel driver (15.9.1.2, released 8/22/2013) for the wireless card (Centrino Advanced-N 6205). The setting adjusts the "roaming aggressiveness". I can only guess this means how often the driver goes out and tries to find a "better" signal and/or bandwidth. The card supports a/b/g so the calculus is complex as to what constitutes "better", and I have no idea how sophisticated the algorithm the driver uses is.
That said, if I set the "aggressiveness" to the most aggressive setting, things work somewhat better. They are still not as a good as other wifi managers bundled with competing products (specifically HP, Toshiba, and Apple so far), but it helps. It does appear that more of the time now, the AP having the best signal appears to be the AP the laptop is attached to.
Lenovo, please consider that forcing your customers to dig around in arcane driver settings and relying on the whims of driver writers and hardware companies to do things correctly and well, is a recipe for failure. Your customers are just going to get annoyed and say to their colleagues, "My old Toshiba seemed to do a better job of WiFi connections. I think next time, I'm going to have IT get me one of those again." And, of course, that colleague will look a lot harder at buying the Toshiba instead of the Lenovo, as well. Wifi connectivity is a very big deal for people who have to move around - and lets not forget, this is a laptop we're talking about, which is explicitly designed to, well, be moved around.
I apologize for being so pedantic, but it often takes such measures to get managers in these companies who control programmer time, to take these issues seriously and allocate the programmer resources to fix these problems.
The problem I am having is still not considered "fixed." I would very much like to hear any other solutions that work better. I would love to hear from Lenovo on the matter. Still waiting.
Thanks.

Can I connect my iPod classic or universal dock with optical

Can I connect my iPod classic or universal dock with optical?

Well, no... not at least with the Apple docks.
Optical Audio is also called S/PDIF. It is a purely digital signal designed for specific kinds of home theater and HIFI systems.
The iPod classic does not have such a connection... that being said, HOWEVER
There are some iPod docks that use S/PDIF out.

Does this help you?

After updating my wife's iPad to iOS6 the ipad will not connect to wifi on certain wireless routers. What can we do? Also, same for iPad mini with same router. But iPhone that has iOS5 has no problem connecting.

Need help. Before updating to latest software iOS6 the iPad had no issues connecting on our home router. After updating the iPad will not work. We have a mini iPad with same issue. But I have a iPhone 4S that I chose not to update to iOS6, still has iOS5. It connects no problem to router. Our computers have no issues connecting to router either. There is a software issue with iOS6.0.1 that will not allow certain routers to communicate. What can I do? Also, the mini iPad stated a newer version of software is out, version 6.0.2 which is supposed to correct the wifi problems. It has helped but still haven't connectivity issues. However, the iPad states software is up-to-date so we cannot update to 6.0.2 even through connecting to computer on iTunes. How can that be?

Try going to settings, reset , reset network settings.
