Discoverer Parameter

Dear All!
I'm working with oracle Discoverer. I created one report in Oracle discoverer with parameter 'period_name'. I chacked mark the check box for 'user can enter multiple values' against parameter. But when i'm goint to run that report it does not showing me the "arrow" for selecting multiple values from list. its only give option to select only one value against parameter. But i want to select multiple. So i dont know what could be the problem. Please someone give me solution as soon as possible..
Regards
Ahmed....

Maybe I'm missing something, but couldn't you use that same condition in Discoverer?
Under "Item", you'd select "create calculation" and build "nvl(vehicle_number,:p_vehicle_number)",
use "=" as the operator,
and :p_vehicle_number as the value (where p_vehicle_number is the parameter)
Or are you saying that's what you're doing, but still not getting the items with no vehicle_number? In that case, it may be a matter of how the tables are joined in the business area (i.e. you may need to add an outer join to the table that contains the vehicle_number).

Discoverer Parameter : ICX: Discoverer Parameters

Hi Experts,
ICX: Discoverer Parameters profile option : is pointing to the EBS URL and is set as exitURL : *****
In the MOS : its is gives as : ICX: DISCOVERER PARAMETERS (ICX_DISCOVERER_PARAMETERS)
at the site, user or responsibility level and it will be added automatically to
the URL when an E-Business Intelligence (BIS/EDW) analysis workbook is called .
But i did not understand that ,
And i open the URL gives under this profile option and it is directing to Oracle apps Homepage but it saying as Discoverer Parameter.
Can someone please give me some more information on it why this profile option is pointing to EBS URL.
I am using EBS : 11510

Discoverer parameter issue

I need to use the same pair of parameters for a query composed by "union all" with three independent queries.
Consider the following example:
create table docs(supplier varchar2(20), doc_date date, doc_num varchar2(10), amount number);
insert into docs values ('Alfonso', sysdate-3, 'doc00001', 100);
insert into docs values ('Alfonso', sysdate-3, 'doc00002', 20);
insert into docs values ('Alfonso', sysdate-2, 'doc00003', 50);
insert into docs values ('Alfonso', sysdate-2, 'doc00004', 10);
insert into docs values ('Alfonso', sysdate-1, 'doc00005', 80);
insert into docs values ('Alfonso', sysdate-1, 'doc00006', 20);
insert into docs values ('Alfonso', sysdate, 'doc00007', 40);
insert into docs values ('Alfonso', sysdate, 'doc00008', 50);
commit;
with calendar as (select (sysdate-3) date_from, (sysdate-1) date_to from dual)
select d.supplier, max(trunc(c.date_from)) doc_date, max('suma al '||c.date_from) document, sum(d.amount) amount
from docs d, calendar c
where d.doc_date <= c.date_from group by d.supplier
union all
select d.supplier, trunc(d.doc_date), d.doc_num, d.amount
from docs d, calendar c
where d.doc_date between c.date_from and c.date_to
union all
select d.supplier, max(trunc(c.date_to)), max('suma al '||c.date_to), sum(d.amount)
from docs d, calendar c
where d.doc_date <= c.date_to group by d.supplier;
SUPPLIER DOC_DATE DOCUMENT AMOUNT
Alfonso 15/12/09 suma al 15/12/09 120
Alfonso 16/12/09 doc00003 50
Alfonso 16/12/09 doc00004 10
Alfonso 17/12/09 doc00005 80
Alfonso 17/12/09 doc00006 20
Alfonso 17/12/09 suma al 17/12/09 280
In the example, I use the static values (sysdate-3) and (sysdate-1)... these values were that I want to pass to Discoverer
But in Discoverer, I only can use a parameter with conditions (i.e. the where clause) in a folder
Any ideas ?
Thanks in advance
Alfonso

Hi,
Yes, the query should have a group by as shown below. Of course, you never enter a group by when you are setting up a query in a Discoverer workbook, you just add the supplier, create the calculations and condition, and add the sort order.
select supplier, max(least(:date_to, doc_date)),
max(case when doc_num 'summary' and doc_date <= :date_from then 'suma al '||:date_from
when doc_num <> 'summary' and doc_date <= :date_to doc_num
when doc_num = 'summary' then 'suma al '||:date_to
end),
sum(amount)
from supplier_folder
group by supplier
where doc_date <= :date_to
order by max(least(:date_to, doc_date))
You don't need to do the summation in the view, you can do it all in the workbook as shown above. The view/custom folder only needs to return all the records you need in the workbook, it doesn't need any group by, so it can just union all the records together as shown in my first query. You can do the summing in the workbook after the parameters have been applied, therefore the view does not need to contain any parameters or any group by.
If you really do want to put parameters in a view then you need to use session parameters, implemented by using database contexts. See the LearnDiscoverer blog for more details.

Where-Clause with function(entered static parameter)

Hello,
I have no clue on the way to deal with this issue.
Basically, for performance, I removed a join with a table, and replaced it by a call to a function within the where clause. This function only convert the entered date into an id, in order to compare with the id in the selected table.
I knew (I think I'm right!!) that if I put a function into a where-clause, then the function is called at each row.
As the parameter of this function is a Discoverer parameter, and therefore, it's a static value, I wanted to know whether with Discoverer, there would be a way to convert the entered Discoverer parameter value into a constant that I could use within my where-clause.
To summarise, hete is the face of my query, at the moment:
SELECT myColumns
FROM myTables
WHERE thisID < myConvertedDate(:RefDate);
I would like to do this :
The User enters the :RefDate, I convert it and save the result into a constant.
Then, my query would look like :
SELECT myColumns
FROM myTables
WHERE thisID < myConstantFromDate;
I hope that my explanation is clear, and that one of you will be able to advise me.
Thanks,
Olivier

Hello Nigel,
I am not too sure that the function is called at each row. This is just my thought, from my "average" knowledge of SQL. We cannot run tkprof at the office, in order to get a better understanding.
And also, the fact that goes towards this direction is that, when I add the call to my function in the where-clause, I have the impression that the query runs more slowly than without the call.
I reckon that it would be great if the optimizer notices that the function is called with the same value, and returns always the same result.
Thanks for your comments,
Olivier

HIding discoverer parameters in URL

I was wondering if it is possible to hide or otherwise encrpt the Discoverer parameter values in the URL.
I understand how to hide static parameters, but could not find a way to hide dynamic paramters. We need the abilitiy to hide these parameters so a user could not change the parameter values in the URL itself.
For Example:
Oracle Portal site has three dropdown lists. These values are dynamic and need to be passed to discoverer/plus in a secure method.
Let's say these values are selected. School=1234 District=123456 Role=staff
The discover/plus report will then take these values and display the proper data. It's URL will then be https://www.server.com/discoverer/plus?
School=1234&District=123456&Role=staff
If everything was static, then we could implement what you recommended, but we need a secure, dynamic method.
YOur guidance is greatly appreciated.

OK. It looks like the Adobe article has a link to the topic
in the second sentence! Which I breezed right passed: "Passing
request data with URL fragments."
Apparently there is no direct URL for this page of
information. I'll take a look now.

'Connect By' and 'Start With' in Discoverer

Hello,
I have a hierarchal query to show all child organizations under the parameter ':Parent_ID'
This is the query, I execute it in SQL Developer normally:
SELECT el.organization_id_child, ch.name,level*
FROM hr.hr_all_organization_units org,*
hr.PER_ORG_STRUCTURE_ELEMENTS el      ,*
hr.hr_all_organization_units ch*
WHERE el.org_structure_version_id         = 61*
AND org.organization_id                     = el.organization_id_parent*
AND ch.organization_id                      = el.organization_id_child*
START WITH el.organization_id_parent = :Parent_ID*
CONNECT BY el.organization_id_parent = PRIOR el.organization_id_child*
in the below line:
START WITH el.organization_id_parent = :Parent_ID*
The hierarchal query will start with parameter value to show all childes under that organization...
How can I use this simple query in Discoverer !! I am trying to find the START WITH in the discoverer also can not put this query in a new custom folder without removing the parameters.
Please Help...
Regards
Edited by: adelshehri on Oct 21, 2009 2:47 PM

Hi,
If you need to use the hierarchical query then you will not be able to pass a Discoverer parameter directly to the start with clause in the custom folder.
However, you can use a database context as a session parameter and use this parameter in the customer folder. More details on this can be found at LearnDiscoverer
Also you could put your hierarchical query into a table function passing the parent_id as a parameter to the table function. Then in your custom view you would join this to a table that returns the list of parent ids that you wish to use. e.g.
select f.organization_id_child, f.name,level
from hr.hr_all_organization_units par
, table (hierarchy_function(par.parent_id) f
where par.organization_id = :parent_id

Parameters to collect dynamic user input

Hi all, I need to create a discoverer parameter which collects one or more group's name (this parameter is connected to a LOV);
After this, I need to create a condition where this parameter (which could be only one values, or a collection of values, selected from the LOV) is passed to a function in order to set a variable (a collection variable) on the DB.
So, I defined this function on my DB and for this parameter I create a particular type
CREATE OR REPLACE TYPE group_name_type IS TABLE OF VARCHAR2(200);
My problem is the PL/SQL Registration with Administrator, because it doesn't let me register a function which has a parameter with a collection datatype.
Also I red that is not possible pass a parameter to a function when this parameters collects more than one values (when is connected to a LOV)
Is there a way, or a workaround to fix this problem, in order to set on the db my collection variable with the all the values chosen from Discoverer ?
Thanks in advance
Alex

how can i make this as an parameter?

Hi Prashant,
Subqueries are not Supported in Conditions..As of Disco Plus Rel 10.1.2.54.25
A plausible workaround can be:
1. Create a View with foll. Query
create or replace view TEST_VIEW as
select hpah.EMPLOYEE_NUMBER emp_no,hpah.FIRST_NAME,hpah.LAST_NAME,hpah.PERSON_NAME,
--hpah.JOB_NAME,hpah.ASSIGNMENT_ORGANIZATION_NAME,
hpah.ASSIGNMENT_TYPE,hpah.USER_ASSIGNMENT_STATUS,
SUBSTR(pj.name, 1, instr(pj.name, '.', 1, 2) -1) job_code,
SUBSTR(pj.name, instr(pj.name, '.', 1, 2) + 1) job_title,
(select haou.ATTRIBUTE1 from hr_all_organization_units haou
where haou.ORGANIZATION_ID = hpah.ASSIGNMENT_ORGANIZATION_ID ) Function,
(select haou.ATTRIBUTE2 from hr_all_organization_units haou
where haou.ORGANIZATION_ID = hpah.ASSIGNMENT_ORGANIZATION_ID ) org_desc,
SUBSTR(hpah.ASSIGNMENT_ORGANIZATION_NAME, 1, 6) dept_code,
SUBSTR(hpah.ASSIGNMENT_ORGANIZATION_NAME, 7, LENGTH(hpah.ASSIGNMENT_ORGANIZATION_NAME)) dept_title,
hpah.GRADE_NAME,hpah.LOCATION_NAME,hpah.SUPERVISOR_NAME,
hpah.PERSON_START_DATE,hpah.ORIGINAL_DATE_OF_HIRE ,
hpah.SALARY_BASIS,hpah.BUSINESS_GROUP_ID,hpah.ASSIGNMENT_ID,
decode( hpah.SALARY_BASIS, 'ANNUAL', ppp.proposed_salary_n,
'HOURLY', (ppp.proposed_salary_n *2080),
ppp.proposed_salary_n
) salary,
sysdate run_date
from
hrfg_person_assignment_history hpah ,
per_pay_proposals ppp,
per_pay_bases ppb,
per_grades pg,
per_jobs pj
where hpah.ASSIGNMENT_ID = ppp.ASSIGNMENT_ID
and hpah.SALARY_BASIS = ppb.PAY_BASIS
and hpah.BUSINESS_GROUP_ID = ppb.BUSINESS_GROUP_ID
and hpah.GRADE_ID = pg.GRADE_ID(+)
and hpah.JOB_ID = pj.JOB_ID (+)
--and hpah.EMPLOYEE_NUMBER = 100779
order by hpah.EMPLOYEE_NUMBER
2. Create another table say TEST_TAB
create table TEST_TAB (emp_no, start_dt) as
SELECT hpah2.EMPLOYEE_NUMBER , MAX(hpah2.PERSON_START_DATE) PERSON_START_DATE
FROM hrfg_person_assignment_history hpah2
GROUP BY hpah2.EMPLOYEE_NUMBER
3. Add both of them in Disco Admin and create a join between TEST_VIEW.emp_no and TEST_TAB.emp_no
4. Bring both these Objects in a new report in Disco Plus
5. Create a New Parameter (Base it on PERSON_START_DATE Col of TEST_TAB)
6. Choose Option Create Condition with operator <=
7. Checkmark "Require User to Enter a Value
8. Execute Report
I believe this should work. Either ways let me know if it helps or u get another workaround. (This scenario looks quite interesting)
Thanks,
Chinmay

Error while running a Discoverer Workbook with parameter from command line

I am trying to run a discoverer report from command line and export the results in xls on to my local machine. I could do it fine for a simple workbook, but if I add a parameter(madatory) to the workbook and run it from command line specifying the parameter value I wanted to run the report for, I do not get any results. Here is the command line I am using.
dis51usr.exe /connect user/password@database /apps_user /apps_responsibility "System Administrator" /eul EUL_US /open C:\Disco\Test.DIS /sheet Testsheet /parameter Period Jan-07 /export xls C:\Disco\X.xls /batch
Parameter value is entered in correct format(Jan-07).
When I removed /batch from this to see if I get any error, Discoverer Desktop opened up, logged in and gets terminated saying 'Oracle Discoverer Desktop has encountered a problem and need to close. We are sorry for the inconvenience.'
Did anybody come across this issue before?

Hello,
If you have a few minutes, Windows is also aborting for me:
the differences are, my situation is:
a) am running the command line from a .bat file
b) am NOT running with parms, want the discoverer query to come up for the user
c) am running a query from the database
i am signing in as myself BUT running a query that was created by a generic user called SREG
c) if i run the .bat file from Windows Explorer, the query opens fine
d) if i execute the .bat file from within Microsoft Access using the shell command,
the query opens and then aborts RIGHT BEFORE the parm screen would display
e) btw, if i modify the .bat file, to run a query from MY database signon, then (d) - running .bat file
from vb using SHELL command works
Do you have a ideas as to why (d) does not work? I would be very grateful for your time, tx, sandra
this is what i posted yesterday, tx: Re: Running Discoverer command line

Parameter form using LOV based on SQL to pass param to Discoverer portlet

Hi all
I have a design issue:-
I want to create a parameter form in Oracle Portal to allow users to select the department using searchable LOV (like the torch that is there in various oracle products) and pass the selected parameter to the Oracle Discoverer worksheet portlet. The LOV values is required to come from a SQL query which in turn is dependent on User_name varia ble from the session.
I am looking for any out of the box portlet which can be configured to achieve the same. Any help or pointers in this regard would be greatly appreciated.

How can I pass dynamic value as a user input parameter in discoverer?

Hi,
I have a requirement for a discoverer report like this: The report will display only details for Suppliers that have expired (or soon to be) Insurance details. That is the Expiration Date is less than or equal to the day the report is being run plus any days specified in the Number of Days in the Future Parameter.
The sample code as:
SELECT s.segment1 vendor_number
,s.vendor_name
,flv1.meaning classification
,pca.certificate_number
,pca.certifying_agency
,pca.expiration_date
,flv2.meaning status
FROM ap_suppliers s
,pos_bus_class_attr pca
,fnd_lookup_values flv1
,fnd_lookup_values flv2
WHERE pca.vendor_id = s.vendor_id
AND flv1.lookup_code = pca.lookup_code
AND flv1.lookup_type = pca.lookup_type
AND flv2.lookup_code = pca.class_status
AND flv2.lookup_type = 'POS_BUS_CLASS_STATUSES'
AND pca.expiration_date <= trunc(sysdate) + <No. of Days in the Future>
order by pca.expiration_date asc
Now the parameter is Number of Days in the Future (Enter the number days in the future to extract the data. This will default to 0).
Is it possible in discoverer to do so as in query i do that like a condition as pca.expiration_date <= trunc(sysdate) + <No. of Days in the Future>.
How can I pass <No. of Days in the Future> as a user input parameter in discoverer?
Please help.

Hi,
All you need to do is to create the condition in the discoverer instead of in the query.
Create a custom folder containing the following sq (note that i removed the condition)l:
SELECT s.segment1 vendor_number
,s.vendor_name
,flv1.meaning classification
,pca.certificate_number
,pca.certifying_agency
,pca.expiration_date
,flv2.meaning status
FROM ap_suppliers s
,pos_bus_class_attr pca
,fnd_lookup_values flv1
,fnd_lookup_values flv2
WHERE pca.vendor_id = s.vendor_id
AND flv1.lookup_code = pca.lookup_code
AND flv1.lookup_type = pca.lookup_type
AND flv2.lookup_code = pca.class_status
AND flv2.lookup_type = 'POS_BUS_CLASS_STATUSES'
Then create a discoverer report using this folder using all fields.
Create a new calculation as (use this exact syntax):
Sysdate + :No_of_Days_in_the_Future
Create a new condition:
pca.expiration_date <= <your calculation>
To complete it add a sort as you did in the SQL.
That's it.

How to passing multiple values for a parameter of discoverer(url parameters

Hi All,
I am trying to pass multiple values for a parameter of disco report. I am trying to include my url for discoverer viewer report. the values has the following

'sfophiee,angela'
Thanks and Regards
Venkat

Hello Venkat,
I know there are some problems with 10.1.2.0.2, maybe if you haven't done yet you can try with 10.1.2.2, assuming this version should be working for multiple parameter values :
OracleAS Discoverer 10.1.2.2 is installed with the following patch :
Patch 4960210 PLACEHOLDER BUG FOR AS/DS 10G R2 PATCH SET 2 10.1.2.2
So, once installed you can try adding your parameter as param_<parameter_name>='sfophiee,angela'
Hope this helps, otherwise feel free to log a Service Request to Support.

Passing parameter to a query in Discoverer Admiin custome folder.

I am developing a report in which I need to paa in the request Id as parameter to display the user the data corresponding to that request Id. However the query is very complex and If I am enetering the request Id in Discoverer Desktop se as Condition for the workbook created the report takes a lot of time to generate. Is there any mechanism through which I can pass the parameter directly to the Custome folder query. As this will reduce my computation time since all the joins will be done only for the rows with that given request Id rather than for all the rows which is happenning correctly.
Thanks.

Hi,
Well there is no straight forward way to do that.
There is a work around to get that functionality by using outer tables or context.
Take a look at the following posts:

Validating Date parameter in discoverer

Hi
In the discoverer is it possible to validate or restrict the users to enter the wrong format of the date e.g. if the date format to be entered is dd-mm-yyyy, the system should not allow the users to enter mm-dd-yy,
Is it possible to put any validation?
As of now what is happening is discoverer is not telling me any thing after running for few minutes i am not getting any result, after that if i check i found that the date is in the wrong format
Regards
Ramesh Kumar S

Hi
If I may throw an aside in here. If your users are using 10.1.2 Plus there should be no need for users to key anything into any date parameter because Discoverer now has a calendar for this use. I find it much easier to teach my users to use a calendar than to try and teach them how to key dates in correctly.
One other thing you might want to consider if you have not already done so is to standardize a date format across your entire Discoverer installation. Then the date format will be obvious because its the same one they see all of the time.
Nevertheless, if you still want a mechanism to trap what users are keying it is possible to create functions that trap formats displaying appropriate error messages.
Best wishes

How to pass parameter in Discoverer inner query PLZ give solution-URGENT

Hi All,
My need is I have a query in Disco Admin which has inner query as mention below:

We are creating a workbook using Diso Plus and creating a parameter on Business_date which is date partitioned, but issue is in inner query(select * from t_FacilityExtract) is picking whole data which has millions of rows.
Plz help me how to filter inner query.
It is just a sample query.
Plz help me as soon as possible.
Thanks in advance

Hi,
Generally, using database contexts is the best way to pass parameters to folders defined in Disco Admin. You can look at this posts or download a article on using contexts with Discoverer from my website (www.cabotconsulting.co.uk).
