Row wise init block has no value defination.

Hi Experts,
I ahve requirement where i need to pick the department of loged in users in dashboard prompt.
So I created the session variable with row wise and written the query:
SELECT DISTINCT 'Department', Department_Name FROM tableA WHERE A.LOGIN_ID= ':USER'
But I get this error in answers:
The session variable, NQ_SESSION.Department, has no value definitions

Thanks for your help !
I created a session variable UNAME
SELECT 'VALUEOF(NQ_SESSION.USER)' FROM DUAL
Then I created the second variable with row wise init block.
SELECT DISTINCT 'Department', Department_name FROM Department A WHERE A.LOGIN_ID= 'VALUEOF(NQ_SESSION.UNAME)'
in second init block i.e. for department i added the init block(Uname) in execute precedence.
Still I am getting the same issue..any help pls?
Thanks.

Row wise init block problem

Hi experts,
We have row wise init block for project1(Connected to db1).
and there are other project2(Connected to DB2) in single rpd.
When db1 is down then we got the error in obiee appication.
Requirement is if db1 is down only project1 should be down not the project2.
is there any suggestion.
Thanks,

OBIEE 11.1.1.6.2 Row Wise Init for Roles variable

Gurus,
Why is the NQ_SESSION.ROLES ( Row Wise Initialized ) behaving differently when compared to other Row Wise initialized session variables.
I am using EBS Authentication and Authorization for OBIEE, so my authorization query is
SELECT DISTINCT 'ROLES', RESPONSIBILITY_KEY
FROM FND_USER,FND_USER_RESP_GROUPS, FND_RESPONSIBILITY_VL
WHERE FND_USER.user_id=FND_USER_RESP_GROUPS.user_id
AND FND_USER_RESP_GROUPS.RESPONSIBILITY_ID = FND_RESPONSIBILITY_VL.RESPONSIBILITY_ID
AND FND_USER_RESP_GROUPS.RESPONSIBILITY_APPLICATION_ID = FND_RESPONSIBILITY_VL.APPLICATION_ID
AND FND_USER_RESP_GROUPS.START_DATE < SYSDATE
AND (CASE WHEN FND_USER_RESP_GROUPS.END_DATE IS NULL THEN SYSDATE ELSE TO_DATE(FND_USER_RESP_GROUPS.end_Date) END) >= SYSDATE
AND FND_USER.user_name = 'VALUEOF(NQ_SESSION.USER)';
Now I plan to use these Roles( EBS Responsibility name) which I have populated in a DB table against some Cost Center and below is the how I view the data in DB.
ID | PROFIT_CENTER | RESPONSIBILITY
0 | 0 |0
1 | 100 |BI_Fin_Role
2 | 200 |BI_P2P_Role
3 | 300 |BI_Inv_Role
Then my Profit Centers Initialization Block is now
SELECT DISTINCT 'PROFIT_CENTER', PROFIT_CENTER FROM WC_OBIEE_PC_SECURITY WHERE RESPONSIBILITY IN (VALUELISTOF(NQ_SESSION.ROLES))
So User1 has BI_Fin_Role and PC_Security Role so does the User2 has BI_Inv_Role and PC_Security now when User1 logs in they should see only 100 Profit center data and User2 should see only 300.
I have created data filter for that application role (PC_Security) and limiting with "Dim.Profit Center"."Profit Center" = VALUEOF(NQ_SESSION."PROFIT_CENTER")
However first problem I encounter is there is no value definition for PROFIT_CENTER, snap that means the VALUELISTOF(NQ_SESSION.ROLES) value is not being passed or recognized by whenever BI Server sends that query to DB.
This is confirmed by my query log which says:
[2013-04-29T12:49:06.000+00:00] [OracleBIServerComponent] [TRACE:5] [USER-39] [] [ecid: 11d1def534ea1be0:48033065:13e4213bbd0:-8000-0000000000008dc8] [tid: 47796940] [requestid: fffe0313] [sessionid: fffe0000] [username: ] -------------------- An initialization block named 'PC_Security', on behalf of a Session Variable, issued the following SQL query: [[
SELECT DISTINCT 'PROFIT_CENTER', PROFIT_CENTER FROM WC_OBIEE_PC_SECURITY WHERE RESPONSIBILITY IN (VALUELISTOF(NQ_SESSION.ROLES))
Returned 0 rows. Query status: Successful Completion
So I try to issue the SQL to BI Server thru Issue SQL Directly:
SELECT "Profit Center"."Profit Center" FROM "SLA Details" WHERE "Profit Center"."Profit Center" = VALUEOF(NQ_SESSION.ROLES)
and the query log gives be the below log which blew my mind as its being delimited by ';'
select distinct T1260626.ACCOUNT_SEG3_CODE as c1
from
W_GL_ACCOUNT_D T1260626 /* Dim_W_GL_ACCOUNT_D */
where ( T1260626.ACCOUNT_SEG3_CODE = 'BIAuthor;BIConsumer;PC_Security;BI_Fin_Role;AuthenticatedUser' )
I have other Row Wise Init blocks for HR_ORG which when fired and used in reports give be stings ('1000','2000',...) which is what I was expecting to see in the filter and query here.
Am I doing something wrong here can someone please point me to right direction please.
Any help is much appreciated.
Thanks,

This is because the ROLES variable in OBIEE 11g is designed to retrieve the LDAP or DB groups etc.. in form of semicolon delimiters this would be not the same case with other Row Wise init blocks.
Refer to : OBI 11g - LDAP and semicolon-delimited string for Groups [ID 1274964.1]

Row Wise Intitialisation block

anybody tell me in which stiuations we use row wise initialisation block.
please explain elaborately?
Thanks in Advance.

User,
To hold multiple values in a variable we normally use Row-wise Initialization blocks

Does Row Wise Initialised block effects the performance of OBIEE 10.1.3.2.0

Hi,
I am trying to implement the security in my application using row wise initialisation block. Could any one help me with below mentioned doubts:
1) Does it effect the performance of the OBIEE server.
2) Cons with row wise initialisation block used for implementing security which uses Oracle customise function in it. this initialisation block is been created for implementing 2 level security.
Thanks
Savita

Savita,
Answers to your questions are as follows:
*1) Does it effect the performance of the OBIEE server.*
No. This is part of the Oracle BI Repository modeling process for Oracle BI 10g.
*2) Cons with row wise initialisation block used for implementing security which uses Oracle customise function in it. this initialisation block is been created for implementing 2 level security.*
There really aren't any cons. To get the security you are seeking row-wise security in Oracle BI 10g is the route you must take. In addition, this process is used widely in Oracle BI 10g for numbers of consecutive users and total users/groups in an LDAP or security group table ranging from hundreds to tens of thousands with nothing but success. So, don't worry about implementing this as your implementation will be sound by configuring row-wise security.

Initialized values for Init blocks disappear at random

Hi everyone
I have a strange scenario and would appreciate your help with some ideas on how to troubleshoot this.
We have OBIEE 10.1.3.4. It is a BI Apps 7.9.6.1 environment and OBIEE is integrated with EBS. Everything is working 100% fine and all initialiation blocks are initialized succesfully. Now iit has happened a couple of times that the init blocks seems to "lose" their initialized values. For example, CURRENT_FISCAL_YEAR will be initialized to 2011. Then out of the blue, next time you log in this init block has the value of 2008, which is the default initializer. The servers are all up and there are no errors.
Any ideas about what is going on here?
Thank you

Check the SQL query in init block.It will take default value if SQL query does not fetch any record.
I guess you have created a repository variable.

Sandeep

Using row-wise multi-value GROUP system session variable in report filter

The title says it all except I am using 10g OBIEE.
What I want to do is filter on the dynamic system session variable GROUP created in a row-wise initialization block.
The GROUP vriable is being set up correctly and it shows the user dynamically put into the correct groups in Answers.
(Using the admin tool and looking at the user session, only the initial authentication block variables show up.)
But if I want to filter using the value of GROUP it doesn't work.
The obvious way is to choose the filter icon, then choose Add -> Variable -> Session, enter GROUP, and then display results.
It comes back with no rows.
Any idea how to do this? I've tried lots of things but none of them work either producing no rows or an error.
This is the kind of Answers SQL this report is resulting in, which makes sense to me, but produces no rows.
SELECT "Package Virtual Group (Dim)"."Package Virtual Group" saw_0, "Contact (Fact)"."Contacts All Count" saw_1 FROM "Case/Transaction/ABC" WHERE "Package Virtual Group (Dim)"."Package Virtual Group" = VALUEOF(NQ_SESSION."GROUP") ORDER BY saw_0

The question is this:
how can I filter a column in Answers using the GROUP session variable which had been initialized in a row-wise initialization block?
I can find no way to do it. Mostly it returns no rows.Hi,
we had a similar requirement, where we have an external name that has project number values. We used row wise initialization to capture all the projects that a user belongs to. Then, we applied the filters at the RPD level, instead of doing it at the report level. From you requirement I see that you are trying to filter the groups based on user login. When a user logs in, he will see the information about the groups that he only belongs to. Correct me if I am wrong here.
Assuming I am right about your requirement, providing the filter that you need apply in RPD.
On all the fact tables are joined to the Package Virtual Group dimension, apply the below filter.
case when 1=1 then (Dim)"."Package Virtual Group" END = VALUEOF(NQ_SESSION."GROUP");
The reason for use of case statement here is, it converts the logical sql to IN Clause, helping us acheive the exact query that we would want.
Please Award points if this helps.

Row wise initialized variable in WHERE clause of other initialization block

Hi,
i've following problem.
I've created a initialization block (called A) that initializes a row wise session variable.
Ex: SELECT X,Y from Z
Select statement returns 3 rows (it's a row wise initialization block!!!)
Then i want to create another initialization block that uses in its WHERE cluase the previous row wise variable
Ex: SELECT W,T from R where F = VALUEOF(NQ_SESSION.A)
I have following error: DB2-UDB: SQL10104 Token ; was not valid, valid tokens: ....
I believe that this error is caused by the fact that VALUEOF(NQ_SESSION.A) is translated by OBIEE in IN (a list of values separated by ; and not by ,).
Can you suggest me a solution?
Thanks
Giancarlo
P.S. I'm using OBIEE 10G

You could avoid this by rewriting it as
select w, t
from r
where f in (select y from z where x = 'A')

Row-Wise Session Variable Initialization Block (Max Rows)

Hi, we have a problem with Row-Wise Session Variable.
We'll try to implemented the security with a External Query and a Row-Wise Initialization Block. But when we'll try to open the Web Obiee and the rows of result of the query is more than 3000 rows, the browser is broken. The access is very slowly.
When the result of Query to Row-Wise Variable is more than 3000 rows and we'll try to open the Web Obiee, we have to close NQServer.EXE process of Obiee Server.
Is there a best practise or a limit rows in the Row-Wise Initialization Block?.
Thanks.

You're Right, the people can't be in 3000 groups.
Is possible I don't explain my problem correctly.
We use this Row-Wise Variable for implement Data Level Security. .
For Example :
I have a fact table with Offices and Office's Sales.
And each Obiee User can see many Offices according to their level of security.
I want filter the fact table using a external SQL table implemented in a Session Row-Wise Variable and a User can have X Offices (In the worst case, 3000 Offices).

Row wise Initialization - Huge LOV

We use External table for Authentication & uses row wise Initialization. It is working perfectly fine, but the issue is the list of values (output) from row wise initialization is pretty large (the output SQL will be at least 30 pages). This is alarming the management and mainly the DBA's and atleast once in a week we are experiencing issues with these SQL's. And in near future, the SQL will be extending drastically as the company has acquired another 2 companies and once the integration is completed, the LOV's from row wise initialization will easily go upto 90 to 100 pages. Let me explain you what I did... We have around 10 Init blocks used for Authentication, but I am mainly concerned about 2 (cf_visibility & sc_visibility) as these are used in Security/Group/Permissions/Report Filters. Each report will for sure have these filters attached. Here cf_visibility Init SQL is (SELECT DISTINCT 'cf_list', CHILD_COMPANY_ID FROM COMPANY_VISIBILITY CV, CLIENT_FACILITY CF WHERE CV.ANCESTOR_COMPANY_ID=(SELECT SUBSTR(':USER', 0, (INSTR(':USER', '.')) - 1) FROM DUAL) AND CV.CHILD_COMPANY_ID=CF.CLIENT_FACILITY_ID AND CV.DW_DELETE_DATE IS NULL UNION SELECT DISTINCT 'cf_list', 0 FROM DUAL) and
sc_visibility Init SQL is (SELECT DISTINCT 'sc_list', CHILD_COMPANY_ID FROM COMPANY_VISIBILITY CV,SERVICE_CENTER SC WHERE CV.ANCESTOR_COMPANY_ID= (SELECT SUBSTR(':USER', 0, (INSTR(':USER', '.')) - 1) FROM DUAL) AND CV.CHILD_COMPANY_ID=SC.SERVICE_CENTER_ID AND CV.DW_DELETE_DATE IS NULL
UNION SELECT DISTINCT 'sc_list', 0 FROM DUAL)
and both are row wise initialization blocks. The filter used for all the Groups is [(DEP.Jobs."Client Facility ID" = VALUEOF(NQ_SESSION."cf_list")) AND (DEP.Jobs."Service Center ID" = VALUEOF(NQ_SESSION."sc_list"))]. This output LOV for this filter is huge as I said earlier.
My main goal here is to reduce the size of the SQL to 1 page, I am planning to do that by replacing the LOV list by SQL (Kind of sub query). I started experimenting with only cf_visibility for now. I replaced the existing SQL with (select 'cf_list',
'SELECT DISTINCT CHILD_COMPANY_ID FROM COMPANY_VISIBILITY CV, CLIENT_FACILITY CF WHERE CV.ANCESTOR_COMPANY_ID=(SELECT SUBSTR('':USER'', 0, (INSTR('':USER'', ''.'')) - 1) FROM DUAL) AND CV.CHILD_COMPANY_ID=CF.CLIENT_FACILITY_ID AND CV.DW_DELETE_DATE IS NULL UNION SELECT DISTINCT 0 FROM DUAL'
from dual)
this returns only 1 row, with 1column as cf_list and the next column with the ('SELECT DISTINCT CHILD_COMPANY_ID FROM COMPANY_VISIBILITY CV, CLIENT_FACILITY CF WHERE CV.ANCESTOR_COMPANY_ID=(SELECT SUBSTR('':USER'', 0, (INSTR('':USER'', ''.'')) - 1) FROM DUAL) AND CV.CHILD_COMPANY_ID=CF.CLIENT_FACILITY_ID AND CV.DW_DELETE_DATE IS NULL UNION SELECT DISTINCT 0 FROM DUAL') Note: USER will be replaced with actual User Name.
But when I run a report in Answers, it throws me an error [nQSError: 17001] Oracle Error code: 1722, message: ORA-01722: invalid number at OCI call OCIStmtExecute. I understand the error as it is clearly mentioned, but my question is "Is there any way not to get that huge list in the SQL"
Let me show you the SQL generated along with the error. As this is a Report filter I am only attaching the where clause of the Query. (where ( T38857.CLIENT_FACILITY_ID in ('SELECT DISTINCT ''cf_list'', CHILD_COMPANY_ID FROM COMPANY_VISIBILITY CV, CLIENT_FACILITY CF WHERE CV.ANCESTOR_COMPANY_ID=(SELECT SUBSTR(''5700.abcde'', 0, (INSTR(''5700.abcde'', ''.'')) - 1) FROM DUAL) AND CV.CHILD_COMPANY_ID=CF.CLIENT_FACILITY_ID AND CV.DW_DELETE_DATE IS NULL UNION SELECT DISTINCT ''cf_list'', 0 FROM DUAL') ).
So I also thought if I use REPLACE function and replace 'Single Quote' before and after the SQL statement with 'Space', it may work. So I edited one of the Group's report filter ((DEP.Jobs."Client Facility ID" = Replace('VALUEOF(NQ_SESSION."cf_list")', ''', ' ') but it is throwing an error in the expression builder itself.
Now I ran out of ideas and seeking any help/guidance from you folks.
I know this is a very lengthy post as I tried to explain the situation as clearly as possible. I hope someone can assist me in resolving this. Thanks for your Time...
-Dinee

can't you make a custom table in the DWH? or use a VPD? Maybe a parameterised database view? What I mean is try to push your logic to the database.

Update report row wise using row buttons and success message

Hi Jari,
Thanks for your reply but i wan't success message in success message region of page and not as popup or alert message.
for report it is classic report but two columns are text field.
Thanks
Manish
Hi,
On Demand process you can use HTP.P to output success message after you code.
Create also exception handler that output error using same HTP.P.
When you call Ajax in JavaScript
var ajaxResult=ajaxRequest.get();
Result you output are in variable ajaxResult.
You can use e.g. alert
alert(ajaxResult);
Refresh report depend lot of what report you have.
There is lot of posts relating interactive report and classic in this forum.
It might be good to create sample what you already have done to apex.oracle.com.
Also creating new post might be good idea as this is answered.
Regards,
Jari

Handling Null Row wise initialization

Hi,
I am creating row wise initialization block to restrict the number of records returned by a Answers.
I am populating a session variable called, REPS_LIST. When I put the condition,
Fact.REP_ID = VALUEOF(NQ_SESSION."REPS_LIST") the group filter works fine.
I want to handle a situation where REPS_LIST is NULL.In that case,I would to get all the rows from my fact. For this, I put the filter like
Fact.REP_ID = IFNULL( VALUEOF(NQ_SESSION."REPS_LIST"), "Fact".REP_ID)
However when i run the Answers report, it says no value definition for REPS_LIST. How can I handle the null condition here?
Thanks,
Vivek.

John,
It appears that the row-wise session variables can be used only with the equality(=) sign. We can't put them in any other function in that the server convert these variables into comma separated string and replaces the = by IN operator. So if I had following filter
Fact.REP_ID = VALUEOF(NQ_SESSION."REPS_LIST")
then it actually gets translated into something like
Fact.REP_ID IN (1001, 1002, 1003....)
As you suggested, I played with the SQL than going behind the above syntax and was able to achieve what I wanted.
Thanks,
Vivek.

Has no value definition - Session INIT Block.

Hi,
I have a Session initialization block for Fetching Departments from a Security table for the user logging in.
One user can have Multiple Departments assigned to him, so i enabled Row-wise initialization in INIT Block.
But when a user not assigned to any departments logs in, i am getting 'Session variable has no value definition' error in all the reports. But i should instead pass a default value when SQL in INIT Block is not returning anything. Like '0'.
How can i do this? please respond.
Thanks
Swami

Hi Swami,
When the query fetches a result set, the variable gets initialized.
But, when the query doesn't fetch any rows, the variable doesn't gets initialized and hence "no value definition" errors out.
So, to avoid this,
In the query itself, place an exception condition which returns '0'.
select dept_name from table
where user_name = ':user'
UNION
select '0' from table
where user_name <> ':user'or you can use like this
select CASE WHEN user_name = ':user' THEN dept_name ELSE '0' END
from tableP.S: Query written orally. (Pls adjust the query accordingly)

Row wise Initialization - "Session Variable has no value Definition"

Hi,
I have gone through other posts relating to this error, but could not find a solution.
I have defined an initialization block with 'Data Source' as SELECT 'TEST_VARIABLE', cost_center from XX_COST_CENTER.
In the 'Edit Data Target', i have selected the 'Row Wise Initialization' option.
When i 'Test' this initialization block, using the 'Test' button, i get the exected output, with all the different Cost Centers being defined.
However, in the Presentation Services when i add a column and change its formula to VALUEOF(NQ_SESSION.TEST_VARIABLE), i get an error
+[nQSError: 23006] The session variable, NQ_SESSION.TEST_VARIABLE, has no value definition.+
Would appreciate some input, to check if i have missed any steps, or am doing something wrong
Thanks & Regards,
Ab

Hi,
Error is caused because no value is returned from the sesision variable for the logged in user, you may check the NQquery.log file to see if the initblock was successfull and if that returned any rows, try setting default value in the session variable
It might also happen when
1. You created the variable as Repository variable in RPD and referring as session variable in Answers
2. It may also happen when you are referring the Session variable Name wrongly in Answers. E.g "Current Week" in RPD (2 Words) and CurrentWeek in Answers (Single word).
Try to use the same letter case for the name of the variable (upper and lower).
Hope this helps.

Row-Wise GROUP init block isn't creating the variable

Hi,
I have an Init Block to set the GROUP variable using row-wise initialization. When I log into Answers with a user, and then check the session variables from Admin Tool, I don't see the GROUP variable anywhere. It seems like the init block is not creating it.
I have execution precendence set up the way it should be. I have the groups created in both RPD and Presentation Services. Below is my simple query to try to get it to work:
SELECT 'GROUP', 'OFFICER' FROM DUAL
UNION ALL
SELECT 'GROUP', 'SUPERVISOR' FROM DUAL
Any ideas?
Thanks
Edited by: oroborus on Mar 24, 2010 1:25 PM

Yes I saw the query in the log, it was successful. I added a simple request to a dashboard to display the value of GROUP, and it seems to be working correctly from there. Do the row-wise variables not show up in Admin tool session monitor?

Row wise init block has no value defination.
