Change of UME data source from ABAP to LDAP

Hi all
we are running a NW04s installation with separate ABAP and JAVA stacks. As we thought our LDAP would be available soon, we configured the JAVA stack as UME data source and of course the ABAP stack for the ABAP-users.
Now it looks like the LDAP will take some time to come. So we would like to change the JAVA data source to the ABAP, so that we can reduce the double work needed for the user administration (JAVA + ABAP).
Now the questions. Once the LDAP will be available we would like to configure the user administration to use the LDAP.
Is this possible, with or without SAP support? Can we get SAP support for this?
Thanks for your answers.
Edmund

I know if you install the portal with an ABAP UME it cannot be changed to something else but assuming you install as database originally then I dont see why you could change from db --> abap --> ldap if you so choose?
There doesnt appear to be any "technical" reason why you shouldnt be able to do this but almost all SAP documentation says you cannot. I assume it has something to do with data inconsistency once the link is broken - probably leaving you with lots of users you cannot delete. I get the distinct impression reading between the lines that you cannot revert back to ABAP when it doesnt work either, which is presumably why SAP do not recommend you even try .....

PS. Ive never actually tried it myself - ive been frightened by SAP telling me it doesnt work!!!!

Error while changing UME data Source of EP.

Hi All,
I am trying to change the UM Congifuration for my EP.
Currently EP is using ECC System as UME data source, Now I am trying to change it from ECC to SCM.
For that I have done SSO between EP and SCM, also I have created SAPJSF id on SCM with roles
SAP_BC_JSF_COMMUNICATION, SAP_BC_JSF_COMMUNICATION_RO, SAP_BC_USR_CUA_CLIENT_RFC and maintained same id on EP under Um Configuration- SAP System.
After doing this while checking the test connection it is giving me following error.
(System ID): com.sap.mw.jco.JCO$Exception: (101) RFC_ERROR_PROGRAM: 'mshost' missing

Thanks & Regards,

Aditya,
This RFC error is encountered when there is no message server host name in this file.
C:/windows/system32/drivers/etc/services
make an entry like this sapmsPBI 3600/tcp
3600 is the port number , try to figure out the correct port number for SCM and update this.
These changes are to be done on your Portal side.
Good Luck.

Changing the data source from DB2 to ORACLE in SBOP 4.0

Hi Gurus,
We have done SBOP 4.0 SP 2 installation successfully on Linux by choosing DB2 as default Database as suggested by SAP as there is some issue with RH LINUX 5.5 version. Now, we need to change the CMS data source back to ORACLE 11G. For that we have to execute cmsdbsetup.sh and go with the option of "copy" (Copy data from another Data Source). We need to provide the target/destination CMS database in my case ORACLE (TNS & CMS user) details. And also we need to provide the source CMS user (DB2) details. As we went with the bundled/default DB2 installation, we are not able to find the cms user name and password (no where during the installation it prompted to provide cms username and password).
What will be the default cms username /password in DB2?
Thanks,
Sandeep

Hi,
The work around is to create/add an extra node (SIA Node) with default servers option for the existing CMS and provided my ORACLE CMS username/password along with the TNS Names using cmsdbsetup.sh. Make sure that this new node is visible in the Servers section of the CMC console (i.e. http://<webappserver>:8080/BOE/CMC-->servers) and also see that all the servers should be running. Then you can delete the old SIA which was connected to DB2 from the CMC->servers.
Thanks,
Sandeep

Transporting migrated data sources from BID to BIQ

All,
I have a 3.x data source which I have migrated to 7.x. Now I want to transport this from BI-D to BI-Q. when I replicate the data source in BI-Q this is likely to be 3.x data source. Will it be overwritten when I transport the data source from BI-D to BI-Q. Is there any thing that I will have to do before moving the transport. Please advise

If you transport the DataSource on R3/ECC from development to QA that's connected to your BW QA, and then transport the DataSource from your BW development to QA environment, there is no need to replicate the DataSource. It may, however, come into your BW QA environment in a deactivated state. If that happens, just activate it in the BW QA environment using the SAP delivered ABAP program RSDS_DATASOURCE_ACTIVATE_ALL.

Portal sizing and UME Data Source

Hi Expert,
Please suggest the sizing approach towards the Netweaver Portal which will be used by about 50 to 60 lacs of customers on internet. New users will be allowed to self-register themselves on the portal. Also what are the recommendations on the UME data source while implementing the portal.
Thank you.

Hi,
As you have already mentioned that no. of users is going to be large (some 500k-600k) it is important to undestand that these are the total number of users. You will have to do following to determine concurrent users:
1. You will have to determine concurrent user phase i.e. peak load phase or time with max. no. of users you can imagine will work with Portal in 1 hours time. Reason to follow this method is large no. of users
2. Categorize your total users in to Low, Medium & High profiles. That means, you should categorize say 500k users in to these three categories. Low category users are those who access portal occasinally. To clarify it even further, users performing not more than 400 screen changes are to be put into this category.
SAP has already mentioned the benchmark figures for these categories:
Low: Users performing 400 dialog steps/week
Medium: Users performing 4800 dialog step/week
High: Users performing 14400 dialog step/week
With this, you will have better clarity of how to determine concurrent users. You can use Activty Reports or ADC Service to initially determine the user trend. You can also make use of Wily Introscope to identify no. of logon requests made. Advantage of using Wily is you can see the data sliced into different time interval like last minute, 10 min, last hour and so on. This shall give you better picture of how many users are making logon within 1 hour.
Also as your user base is large, I don't think SAP recommends to use UME for 500K-600K users. It should be LDAP as far as I can think of. However, do get a second opinion about usage of the DB.

Why I cannot change the generated data source?

Hello all,
I have a generated data source from ODS, now I need to change something on it but the system only allow me to display it even I clicked the pen-glasses icon. Could anybody tell me how?
Thanks
Ryan

Hi Ryan,
You can't the generated data source from an ODS object, this is becasue ODS supplies delta from change log tables and the export data source / info-source structure should be same as of the change log table.
However you can change the generated data source-info source assignment of info-cube.
Hope it helps
Thanks,

Error in generating data source from planning area

Hi experts! I have an error while making data source from planning area:
after the screen when i fill in the data source name (Window name: Generate export data source) i have the SYNTAX_ERROR Message:
Syntax error in program /sapapo/cl_im_extract_ex======cp
the main reason: the type /BI0/9A0IVWKNDGD is unknown
what you can suggest to solve this problem?
Thanks.

Dear Andrey Kudriavzev,
The reason is the program is trying to use the datatype '/BI0/9A0IVWKNDGD' which does not exist in the system.
Go SE11 to cross check if it exists. Check dataelement radiobutton -> enter /BI0/9A0IVWKNDGD -> Choose display option. You would need to create this datatype in the system. I feel there must some OSS Note related to this.
Search for an OSS Note. Raise one if you cannot find the relevant notes.
Regards,
Naveen.

Replication of Data Source from APO to External BI

Hi Experts,
I want to create a data source on DP/SNP planning area & replicate it directly to External BI instead of APO BW. Is it possible to replicate data source from APO to directly External BI? If yes then How?
Regards
Sujay

Hi Sujay,
If you would like to replciate a particular Data source then Go to BW -> TCode RSDS ( Data source Repository)
Data Source = ( specify which you would like to replciate )
Source system = Specify source system name.
Go to Menu option Data Source -> Replicate Data source or you can use CTRL + SHIFT + F2
These steps will replicate only the data source which you would like to replicate.
Thanks,
Siva.

How to use Sql data source from Essbase 9.3.1

Hi All,
How to use Sql data source from Essbase 9.3.1 for ASO cube.Are there any rules and limitations for that.
Do we need to create any data source connection for this purpose. If there please let me know the dteps to create that connection.
Regards

Yes you need to create one DSN connection and you have to use DSN name and login details at the time of building/loading of the outline.
Create DSN
Goto Administrative tools -> DataSources (ODBC) and add the DSN name and specify the Server name of SQL and login details and database.
goto data prep editor and click on File Menu and Click on Open SQL option Next window opens.
There you have to enter the details of the DSN connection and SQL query to build/load.
Thanks,

How to prevent Pivot Table Data Source from being changed automatically?

I have an excel file that contains a Pivot Table that references a table within the workbook (Data Source = "MyTable"). When I save the file and copy it, the copy contains a reference to the original file. Instead of displaying, "MyTable",
it shows "OldFilename!MyTable" where OldFilename is the name of the original file, not the current file.
How do I prevent this from occurring. It is only doing this on my current machine, if I perform these steps on a different machine, the problem does not occur and the Data Source property stays the same as it should.
What setting(s) do I change to fix this problem?
Thank you in advance for your help!

How to get group when the data source from system instead of UME database

Hig guys,
How to get group when the data source comes from backend system instead of UME database?
I tried to use
IUMPrincipal RefGroup = WPUMFactory.getGroupFactory().getGroup(groupName);
But I was not able to get the group. But in "UserAdministrator", I can find this groupName.
Which kind of API can I use?
Thanks in advance!

Ok,
try this:
com.sapportals.portal.security.usermanagement.IGroupFactory ep5GroupFactory = userManagementService.getGroupFactory();
IGroupFactory groupFactory = UMFactory.getGroupFactory();
com.sap.security.api.IGroup group = groupFactory.getGroupByUniqueName(groupName);
IUMPrincipal ep5Principal = ep5GroupFactory.getEP5Group(group);
This should do the trick,

Where is the UME data source configuration XML file stored on the server?

I'm trying to activate windows integrated authentication in my portal server. The java engine's UME configuration has been loaded as a deep AD read only database using the file "dataSourceConfiguration_ads_deep_readonly_db.xml" but I can't find this on my server. I need to modify a couple of parameters in there to activate kerberos principal management. My recent portal training course offered me a completed working example but it was for an ads_flat_writeable_db so I can't simply load that and I need to understand the changes required.
Where to I find the configuration file on my java instance server so I can make the necessary changes to a copy and upload that?

Try to read
https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/e1959b90-0201-0010-849c-d2b1d574768b
UME user data is stored in one or more data sources. Each type of data source has its own persistence adapter. The persistence manager consults the persistence adapters when creating, reading, writing, and searching user management data. Persistence adapters for the following types of repositories are available: 1. Database: See the Product Availability Matrix on SAP Service Marketplace (http://service.sap.com/pam60) for details on which databases are supported. 2. u2022 Lightweight Directory Access Protocol (LDAP) directory: See the Product Availability Matrix on SAP Service Marketplace (http://service.sap.com/pam60) for details on which directories are supported. 3. SAP Systems based on Web Application Server 6.20 You can configure UME to use one or more of these persistence devices in parallel. Users can also be stored in several different physical LDAP directory servers, or in different branches of the same LDAP directory server.

To Change Delivery Schedule Dates coming from Purchase Order

Hi Gurus,
My requirement is i need to change the Delivery dates( Picking date, Transp Planning date, Loading date and Planned GI date ) . The delivery is being made by the Purchase Order through transaction VL10B .The source dates are the dates from the PO. The dates are to be copied for the condition that the order should be of ZDL type and delivery ZXN1. Now there is a routine 301 for this condition .
I tried to change the dates in this routine but these dates are overwritten by a function module SD_SCHEDULING .
So is there any other method or exit or any other routine for this.
I would like to have a copy of the following dates :
u2022     Mat. Staging(PO) = Picking
u2022     Transp. Planning(PO) = Transp. Planning
u2022     Loading(PO) = Loading
u2022     Goods Issue(PO) = Planned GI
u2022     GR End(PO) = Delivery
Please advise.
