Sequence in parent and row level security

Hi,
I have a column with "seq in parent" for the "autogen type" property in Designer.
I also have row level security (RLS) (or fine grained access control) on this column's table.
Since there are data that could not be seen because of the RLS and the sequence is "seq in parent", i get the error :
ORA-00001: unique constraint (string.string) violated
Cause: An UPDATE or INSERT statement attempted to insert a duplicate key.
Example : User A inserts a row and the sequence is 1. User B who cannot see the row inserted by A, inserts its own row. The sequence inserted by B also gets 1 instead of 2 (because he cannot see the existing sequence 1). The sequence is duplicated, hence the error.
Is there a turnaround for this ?
Thank you.

You could consider using a 'real' sequence instead of seq-in-parent. I think seq-in-parent is using something like 'SELECT MAX(seq) FROM'... and that could also fail (depending on the moment this statement is issued) when 2 users are inserting a record.

SAP-BO SSO and Row Level Security

Hi,
We can configure the SAP authentication and able to login InfoView via SAP user name and password. And also, we can import the roles from the SAP system.
When we create a connection to BW cubes from designer, we want to use "Use Single Sign On when refreshing reports at view time" to apply row-level security which is defined at the BW cubes.
In our tests, we use "Use BusinessObjects credential mapping" while creating connection from designer to test the row level security. As you can guess, after importing the SAP user, in CMC screen > Users and Groups > Users, we manually enter the password of the user to the Database credentials part. However, as you can guess, the password of the user's is not static and that is not a good solution.
My question is that, do I need to configure SSO between SAP and BO system or how can I enable row level security?
System Information
Business Objects XI 3.1
SAP Intg. Kit 3.1
Thanks a lot,
Omer

Hi Omer,
please note that only row-level security implemented through authorization variables in BW queries can be used in BusinessObjects. Row-level security defined at cube level will not be applied.
As long as you have used the SAP authentication to log on your BOBJ server, the SAP credentials will be used automatically to get the data from your SAP BW source as long as the "Use Single Sign On when refreshing reports at view time" option is selected in the Database configuration panel (Found in the CMC when viewing the properties of your report) and the option "Use BusinessObjects credential mapping" is selected in your universe connection.
Please note that this will only work for reports that are invoked directly in the infoview. If a user schedules such a report, she/he has to enter her/his SAP credentials explicitely in the Database Configuration Panel appearing in the scheduling assistant window. In this case you can activate SNC trust between your two servers in order to avoid entering a password when the report is scheduled.
Regards,
Stratos

Row level security in Hyperion System 9 - 9.3.1

Hi Gurus,
I have a requirement where the users get to see records in a table based on their localization code. This is currently implemented using views.
The view has a set of conditions which checks the localization table with te employee table. For example, if any of the first manager, second manager etc.. localization code
matches then they get to see records for that location.
The RLS in Hyperion uses Groups to assign security rules. But in my case, the determination is dynamic based on the localization code. And these things change depending on employee movement, transfer, promotion etc..
In such a scenario, can I use RLS only if I know a set Groups of users and where they belong to? Can RLS accomodate my above said requirement?

Obi 11g row level security not working

All,
I am very familiar and have worked with obi 10g row level security and it works pretty easily. Now in 11g not so easy. I am basically setting permissions on data filters on app roles as per the new 11g instructions and meta data guide, however, I never see the filters being applied in the report and also in the nqquery.log. I have tried in vain, and nothing. The filters are never being applied for the test user. I even verified the user is in the specified app role via their my account->app roles tab. Now has anyone had this experience or now is there something that must be done additionally now.
Very frustrated... ;(

Ok, so I have found the solution and ultimately the answer to why the object level and row level security was not being applied. It so happens that the app policy: 'resourceType=oracle.bi.server.permission, resourceName=oracle.bi.server.manageRepositories all' not only allows the management and access to online RPDs; but, IT ALSO DOES NOT APPLY SECURITY/PERMISSIONS IN THE RPD TO THAT USER thus you are super user. So the OOTB BIAdministrator app role which my AD user was being assigned never had any security applied due to this. How I tested:
1) I created a test user
2) Assigned that user to the BIAuthor app role and saw that they had the security applied that I was testing, which was simple object denial and row-level security to just one year on the date dim.
3) Since it was working, I then assigned that user to the BIAdministrator role. This produced that the test user now does not have any restrictions that I set and that were working before. Thus, security/perms in the RPD are not applied.
4). I removed the user from the BIAdministrator app role, kept in the BIAuthor app role and then created new test app role. I mapped that user to this new role along with the BIAuthor role. I then proceeded in creating new app policy with just that policy and assigning the new app role to it.
5) I logged into the presentation services again with this test user after assigning to new app role and policy. My test user again does not have the security being applied and does not get any perms/security that I set and applied in the RPD. On top of that my test user is now able to login in online mode to the rpd via the bi admin tool.

Row Level Security in OBIEE using OID as authentication Mechanism

Hi OBIEE Gurus,
I am trying to implement Row Level Security in OBIEE . Currently I have setup OBIEE to have OID do the user authentication.
I want to implement RLS by doing the following :
1. Have Security Groups defined in OID and assign users with group membership.
2. Import these Security Groups into OBIEE metadata
3. Apply filters to these Security Groups
4. Run Answers requests to see if RLS works or not
Please let me know if this approach works. If this is not the right way or most efficient way to do this, please let me know if there is any document I can follow to accomplish this.
Appreciate your help.

Parent-child hierarcy - row level security

Hi,
Im using OBI 11.1.1.5 and have a problem about row-level security in parent-child dimension.
I have created a parent-child dimension, simlar to:
a1
--a1.1
----a1.1.1
----a1.1.2
--a1.2
----a1.2.1
By using a session variable 'SESVAR1', I want to restrict the visible hierarcy. For instance user 'a1.1' should only see:
a1.1
--a1.1.1
--a1.1.2
To do this I created a parent-child closure table with the whole dataset. Then I created a physical table using select statement with my session variable in repository. Whenever I viewed data in repository, it showed the correct set.
I created a parent-child dimension, using the original parent-child closure table. But since current distance values are different from the original hierarcy, I can not managed to build a security such a security system with this method.
How can I build a security system, that a member can only see its child hierarchy only?
Thanks for answers and links...

According to searches I made in support.oracle and google, it seems that it is not possible to view just a branch of a parent-child tree. Because the closure table is static. Therefore, you can not change the distances of objects dynamically.
This parent-child ability is very frustrating for me. As I understand, parent-child dimension ability can only be used in read-only sources. Any filtering or dynamic changes does not seem possible in this structure. Any changes on parent-child table requires parent-child relation table to be rebuilt.
I couldnt find any functionality of indexcol or choose functions in parent-child dimensions. I think they can only be used in level based dimensions.
Any comments appriciated..

Row-level Security Filters applied to Columns and Tables only? no Areas?

Good day all,
Just quick question (obiee 10.3.3.2) - Is there a way to edit row-level security using Whole subject areas (instead of bringing in the individual Fact tables and applying filters by copying/pasting them).
Follow up question - if I have nested facts in presentation layer (ones preceding with "-" - do I specifically add them to conditions, or would they be inherited by only including parent fact)?
Thanks!

I'm not sure how that would help; by using the Faculty_ID Session Variable I can identify the CRN and Term of all courses a faculty member is teaching. But I don't think that has to do with the problem I am having?

Row Level Security using BO SDK - Dynamic Group and Criteria (where clauses)

To the Universe Gurus out there:
I have a rather daunting task of implementing a Row Level Security on a number of tables within our project using BO XI R2 SP2 with SQLServer 2005. Given the nature of the requirements around this (listed below), I am going to go with BO SDK to accomplish the creation of Restrictions. That said, I need some insight into some of the problem areas I have listed below. Any help is much appreciated.
Background:
We have 11 tables that are to be restricted.
Each table is accessible to potentially 1..* group of users only.
For eg SALES is accessible to ALL_SALES members only.
Each row within each table is accessible to 1..* groups of users only. The restriction will occur on 2 columns Jurisdiction and LineID on SALES table.
For eg
1)Rows with NY Jurisdiction and LineID=123 are accessible to NY_SALES_ADMIN group only initially.
2)NY_ADMIN will then approve that the above rows be open to NY_SALES_INTERNAL group only. This approval in turn will call upon the BO SDK to add a new restriction for the group with appropriate where clause.
3)At a later point, the above rows will be opened to NY_SALES_EXTERNAL group also.
This same concept holds good a number of jurisdiction (more or less static) and a dynamic number of LineIDs. So, if 10000 rows of data corresponding to new LineID 999 and Jurisdiction AK are in the table now, they are initially accessible only to AK_SALES_ADMIN group only. No one else should be able to access it.
Results:
1) With the way I laid out the business rules above, I am ending up with 528 groups.
2) There is a restriction created for a unique combination of Jurisdiction and LineID for each table.
Problems/Questions:
How can I restrict access to the new rows to one group only. I know that I can let a certain group only look at certain data but how can I restrict that all others cannot look at the same.
AK_SALES_ADMIN can look at LineID=999 and Jurisdiction='AK'.
Do I use an Everyone group based restriction? If so, my Everyone group will end up with tons of restrictions. How will they be resolved in terms of priority.
Am I even thinking of this the right way or is there a more noble way to do this?
Regards

the connectinit setting should look something like this:
declare a date; begin vpd_setup('@VARIABLE('BOUSER')'); Commit; end;
The vpd_setup procedure (in Oracle) should look like this:
CREATE OR REPLACE procedure vpd_setup (p_user varchar)IS
BEGIN
DBMS_SESSION.set_vpd( 'SESSION_VALUES', 'USERID', p_user );
END vpd_setup;
Then you can retrieve the value of the context variable in your vpd functions
and set the vpd.

Row level Security in obiee11g

Hello
I am trying to implement Row Level security for some 10,000 users based on the Cost Centers which are about 30,000. I know how to implement the data level security using groups an dapplication roles and creating security filters on those groups.
But There are two issues I am facing :
1. The no. of cost centers are huge i.e 30,000 . So creating these many groups doesn't seem feasible. Any other approach.
2. Cost center has got level based hierarchies having 20 levels and is a ragged hierarchy. There are some users who have access to Parent level node and there are some having access to child level cost centers. What I believed that for users having access to Parent level , I can assign all the child level cost centers and teh security will rollup to provide access to the Parent node (like you have access to California and Florida so automatically you get access to US (Cal + Flo).
But the issue is there could be one user who will have access to the TOp level so I will have to assign all teh cost center (30,000) so that he can get access to the Total Cost Centers. There could be other Managers who will have respective Parent Cost center access leading to assigning them to say 5000 - 10000 cost centers. My fact conatins the leaf level cost centers.
Is there a better approach to handle this.

Row Level Security not working for SAP R/3

Hi Guys
We have an environment where the details are as mentioned below:
1. Crystal Reports are created using Open SQL driver to extract data from SAP R/3 using the SAP Integration Kit.
2. The SAP roles are imported in Business Objects CMC.
3. Crystal Reports are published on the Enterprise as well.
3. Authorization objects are created in SAP R/3 and added as required for the row level security as mentioned in the SAP Installation guide as well. The aim is when the user logs into the Infoview and refreshes the report he should only see data that he is meant to so through the authorization objects.The data security works very much fine when the reports are designed directly on the table but when the reports are built on the Business View it doesnt work hence the user is able to see all data.
Any help in this issue is greatly appreciated.
Thanks and Regards
Kamal

Hi,
In order for row level security to work for you using the OpenSql driver, you need to configure the Security Definition Editor on your SAP server. This is a server side tool which the Integration solution for SAP offers as a transport.
This tool defined which tables are to be restricted based on authorizations.
However since you are seeing the issue on reports based on Business Views, you need to identify whether the Business View is configured in such a way where the user refreshing the report is based on the user logging into Infoview. If the connection to your SAP server is always established with the same user when BV is used then you security definition is pointless.
You can confirm this by tracing your SAP server to identify what user is being used to logon to SAP to refresh the reports.
thanks

Row level security in BI Publisher

Hi All ,
I am using BI publisher for reporting on Siebel system.The issue I am facing is regarding row level security.Even if I am logging with Employee Id, when I generate report ,I have acess to all the information of the other employees.
e.g. If as a cashier I made some entry , when I generate report on collection made by me, its bringing me all the collections made by other cashiers also.
I am generating these report from siebel side.I am not sure if we can apply the rowlevel security to BI Publisher.
Does anyone has used Siebel or EBS with BI Publisher and have row level security ? I am also not sure How to see the reports by loging into BI Publisher .If I am using Siebel or EBS, what is going to be my Data Model or Data Set.
Can anyone help me on this?
Thanks!!

Oracle HRMS has its own security built-in to the schemas. Other modules you will need to customize for your own use.

Setting up Row Level Security in EPM 11.1.1.3

I have been following the Administration guide but failed to setup row level security in EPM 11.1. Please advise which part of my steps are wrong. (note I am using MS SQL Server for the EPM Shared Services and Workspace database, everything under Windows env)
i) Enable row level security in Workspace.
Step 1) Define a ODBC Data Source named "EPM_WS" in Windows. The ODBC Data Source points to the MS SQL Server database of EPM Workspace since it contains the 3 tables (BRIOSECG, BRIOSECP, BRIOSECR) related to row-level-security.
Step 2) Login to workspace, select "Administer"->"Configuration Console". Edit "Interactive Reporting Data Access Services" and add a data source with ODBC->MS SQL Server -> "EPM_WS" as the name of datasource. Restart "Interactive Reporting Data Access Services".
Step 3) Login to workspace, select "Administer"->"Row Level Security". Check "Enable Row Level Security", Choose ODBC->MS SQL Server-> fill in "EPM_WS" as Data Source Name"-> Provide correct user name and password. Click "Save Properties"
Step 4) It always prompt "Server error setting the Connectivity. Recommended Action: Logoff and logon again. If problem persists contact your local security administrator."
Any log I can inspect for the connectivity error?
ii) Configure Row Level Security setting
I know that for Hyperion IR, there is a file row_level_security.bqy comes with the installation. User can use this bqy file to configure the actual row level security setting. However, I cannot locate this bqy file in the EPM 11.1 installation. What is the proper step for setting up the row level security configuration?
thank you very much.

How to check the row level security in TOAD for oracle

Hi ,
for ex, i have 2 types of users
normal user and super user
super user can see the group set (some column name) created by normal user
but normal user can not see the set created by super user
this set crestion aslso has 3 types "U','P',S'
P & S can be viewed by even normal user
but U should not
so here we are having some row level security for the normal user .....
So, in TOAD for oracle how to check that......
Let me know if i'm not clear

Like
I'm the super user....
And some records are inserted to a table by different users ('a' , 'b', etc....)
So,if user 'a' logins then he can be able to see only the records inserted by 'a' only...
how to see in TOAD where such type of scripts (filter conditions) are written.....

Row Level Security Not working for the ECC table.

Hi All,
We have created a crystal report using SQL Driver.
We have set the row level security on PA0001 table so that we can restrict the query based on Company Code.
But when I run the report, it bypasses the row level security and gives access.
Am I missing some configuration?

Hi Ingo,
Security is set up using /crystal/rls transaction. A custom auth object is used for checking the company code with a single field "BUKRS".
This custom auth object is maintained for the PA0001 table.
This object is added at the role level with the restricted access to the Company Code..

Row level security in OBIEE 11g: Which is better: VPD or RPD

We can apply row level security in OBIEE by 2 ways.
1. by Creating Initialize Block in RPD
2. or Applying VPD in Database, which restricts source tables
Which one is more efficient and why?
Thanks,
Sunil Jena

you will have some degree of performance degradation with either approach since you are adding additional filters so I would not use that as the main factor to decide. You need to assess your actual requirements. What is the basis by which you are planning on doing the security. Is LDAP the main basis for the security? Do you plan to use certain roles? if your security is more based on roles at the application level, then it may be easier to define at the Application level (OBIEE)...if its just based on a certain user ID for a set of tables, then perhaps VPD can work. If helpful, pls mark.
