Pass parameters to a report instance, or filter an instance of a report

Hi,
I am using Web Elements as linked reports with no problems for on demand reports but I need to run an instance of a report and then use a web elements/opendocument link to a subset of that data.
Basically I have a report on a college that drills down to campus and then course level. If I have an on demand subreport (via web elements link) to a course, linking course code then it brings up the 20 or so students on that report on the fly - taking < 30 seconds.
The problem is that I need this at Campus level as well. If I do it on the fly by linking on Campus instead of course, it times-out due to the large numbers of student records in the detail level.
If I change the link from the main report to point to the instance of the report I get all records, not just the campus I need (I get all campuses).
I then put in parameters to just select the required campus within the Instance of the report that is run for all campuses. The Instance is created with Parameters set to wildcard values, so that the parameters are available to pass values. I have also tried running the subreport without parameters, but it just displays all records and ignores parameters passed in (unsurprisingly).
I have had other reports working with linked parameters before, but only to the .rpt report - not to an instance.
The report works, but again all reports are displayed because when I checked the parameters they are shown as wildcards, as used when creating the instance, NOT the parameters I am trying to pass to the instance.
If I change the link to go to the Param Instance instead of the last instance (sInstance=Param), then I get an error because the report instance was created with wildcard parameters but the link has campus set, so there is no matching instance as far as Crystal is concerned.
An approximation of the link used is below:
http://...opendocument.aspx?sType=rpt&NAII=N&iDocID=1234&sInstance=Last&lsSAcadPeriod=07/08&lsSparamCampus=E
I cannot simply run an instance of the report for each Campus as there is are additional layers I have left out of this example for clarity (School, CampusType etc).
I need a solution that either allows parameters to work with instances of reports, or filter records in instances of reports.
I hope I have explained this clearly enough - please let me know if not, or if you have any other questions.
Many thanks in advance for any and all help.
Geoff Langdon.

hello arjhay,
webelements 2.3 will not work seemlessly, unfortunately, with xir3.
in xir3 the dhtml viewer has changes in it that are more web 2.0.
things that will not work and are deprecated for webelements & xir3 are the functions in WEViewer. this is due to the toolbar in the new viewer being a widget as opposed to a set of divs. however, opendocument for xir3 will allow one to switch off the toolbar using an opendocument paramter and will also allow one to switch off the new style tab bar.
the new dhtml viewer also does not encase report fields & functions etc. within a form tag. many webelements controls require a form so the new design for xir3 will be to put a new WEFormStart at the top of each report using webelements. what this does is basically start a form in the viewer and allow the controls to function properly.
so in summary there are 2 changes for xir3:
a) each report using webelements must have a WEFormStart function added to the beginning of the report
b) references to WEViewer must be removed from reports that are used in xir3
there will be a new 2.4 function suite out in several weeks and this will contain the new WEFormStart as well as other syntax changes to allow reports to work in xir3.

OBIEE 11G - Issue passing parameters between two reports

Hi folks,
I am struggling to pass parameters between two reports in OBIEE 11G.
My first report contains the following columns: Rolling Year Type (VCHAR), Year(VCHAR), Month(VCHAR), Cost(Double).
My second report contains the following columns: Rolling Year Type(VCHAR), Year(VCHAR), Month(VCHAR), Category(VCHAR), Cost(Double).
My requirement is to pass the Rolling Year Type, Year and Month values from report 1 to report 2.
On the Month column properties of report 1, I have created an Action Link called 'Drill to Category'. I have clicked on 'Navigate to BI Content' and selected Report 2.
Then on Report 2, I have included three filters: Rolling Year Type is prompted, Year is prompted, Month is promted.
When I run the report I always get the following error:
The specified criteria didn't result in any data. This is often caused by applying filters and/or selections that are too restrictive or that contain incorrect values. Please check your Analysis Filters and try again. The filters currently being applied are shown below.
When I check the cursor cache, the filter values are correct. Does anybody have any idea why Report 2 does not display?
When I remove the Month filter, the report works correctly.
I have since changed the third filter to be Month No and although Report 2 does display, it does not pick up the filter on the Month No.
I initially thought this may have been a caching issue and so I have disabled BI Server Cache but this does not fix my problem.
This was never an issue on OBIEE 10G as I found it very easy to navigate between two requests.
Has anyone else experienced problems with passing parameters between two request in 11G?
Any help appreciated.
Thanks
Gavin

Hi,
I once tried this kind of requirement(with dashboard prompts though) and hit at similar issue. I later found out that the problem is with the space in the parameter values. Can you please let me know, if the same is the case with you?
Suppose the parameter passed is "Jan 2010", but the report on the destination takes the value as "Jan" & "2010". Yes, it kind of split the parameter value to two based on space. I think we can notice the filters the destination report got, by enabling filter view.
In this case, since you pass only value at a time, could you try placing the parameter value anyway in double quotes? I think the Server then will understand it as one value.
Thank you,
Dhar

Passing parameters to QBE Reports?

I currently have an SQL Report that I filter dynamically with parameters from the page. I would like to be able to use this same functionality with a QBE Report that the client can more easily specify.
Is it possible to pass parameters to QBE Reports? If so, how?
Thanks,
Mark

As Chetan has correctly suggested, it will be better to use a table to store
the emp no and their pin against their login session ids.
You can have a table as :-
create table emp_pin (
session_id integer,
emp_no integer,
emp_pin integer,
constraint emp_pin_fk1 foreign key (session_id) references <portal_schema>.wwctx_sso_session$(id) on delete cascade
When a user logs into portal, a session_id is created and this session_id is
deleted when the user logs out. The delete cascade rule will clean up your
table entry when the user logs out.
You can get this session_id using the <portal_schema>.wwctx_api.get_sessionid function.
Now you need to create 2 functions that would return the emp_no and emp_pin.
You can then use these functions in the sql query of your reports. This way you
need not use bind variables at all.
Example:-
create or replace function get_empno(p_sess_id in integer)
return varchar2
is
l_empno varchar2(2000);
begin
select emp_no
into l_empno
where session_id = p_sess_id;
return l_empno;
end;
create or replace function get_emp_pin(p_sess_id in integer)
return varchar2
is
l_emp_pin varchar2(2000);
begin
select emp_pin
into l_emp_pin
where session_id = p_sess_id;
return l_emp_pin;
end;
Now, these functions can be used in SQL query of your reports as :-
select <col1>, <col2>, <col3>
from <table>
where empno = get_empno(<portal_schema>.wwctx_api.get_sessionid)
and emp_pin = get_emp_pin(<portal_schema>.wwctx_api.get_sessionid)
and ....
In a form, you can use these functions to set the default values of the empno,
emp_pin fields.

Passing parameters from portlet reports to portlet forms

Hi,
I'm tring to pass parameters between a Report displayed as a portlet in a page ( page 1) and a form displayed in other page ( page 2).
The problem is i can't do this.
I only can pass parameters from a report ( running as normal or in a portlet displayed in a page) to a form running "normal" by using application links. Can i do this between a report that show's me every employees of scott.emp table. Then when i click on each employee, it open's me another page with the portlet form of the specified employee.
I'm not sure i made myself clear. Please send me some feedback.

I have the same problem. Please let me know if this could be done.
In particular my form is a type of "Form on Table/View."

Passing Parameters to RDF Reports with Parameter_list in Forms9i

Hi,
I am trying the Oracle 9iDS, and I encounter a problem.
When passing parameters to my reports, if my parameter contains the space or other special char, I cannot run the report. It give me the REP-56033.
For example, it's my code:
add_parameter(pl_id,TEXT_PARAMETER,' and deptno=56');
Then, when I run the form. It cannot run the reports. In rwservlet/showjobs, I cannot see this job.
And If I change the code to
add_parameter(pl_id,TEXT_PARAMETER,'anddeptno=56');
Of course I cannot get a correct output, but I use the rwservlet/showjobs to get this failed job.
Any one can give me a hand. Thanks!

Of course I use run_report_object. I can run my other report successfully.
Just these report with special char parameter. I can not call them.
And I can search out there are some questions about this problem in the forum. But they all arenot get the answer.
Please help me.
Anyone can try to run your report, or run the test.rdf, which is the demo given by oracle, with a paramters containing a space, such as ' aaa bbb'. You will find that the report cannot run. Even in the showjobs, u cannot find it!!!!
Please!!!

PASSING PARAMETERS TO CRYSTAL REPORTS THRU FORMS!

Hi! all,
Is there someone who passed parameters to crystal reports from
forms 5.0?
The problem is when I call the report executable from the form,
its giving a login prompt again which is not desirable as @ this
stage the user has already logged in once. So is there a way to
pass this as a parameter to crystal or may be any better way???
Thanx for the solution,
Hima

Passing Parameters to a report query

I have built a report query, the query has 3 parameters.
select * from EMP_DETAIL
where
emp=:EMPP
and loc=:LOCP
and seq=:SEQP
When I test the query, enter the parameters manually, it renders and I get my report.
When I add this layout to a standard on screen report region, I can not figure out how to pass the column values to those parameters.
I'll try to explain. I have a report
SELECT * FROM EMP
The users can filter the report down, then when they find the emp they want, I have created a report link that is supposed to run the detail query and have the detail report come up in a PDF.
So lets say they choose employee 0009, the columns have the :LOCP and the SEQP
I want the report query for the PDF print to be filled in and the report rendered and printed. Like I said, I can test the report query/layout from the shared components section but I can not get the column values of say #EMP#,#LOC#,#SEQ# passed to the report.
When I click the report, it appears to run forever. I do not know what is being passed to the report query.

Starting to wonder if my question doesn't make sense.
Does not seem to be something that hard.
I have a APEX 3.0 stored report query and layout loaded via the shared components section. The stored report accepts 3 parameters.
I have an employee report region (Select * from emp) and I have a derived link column that has a pretty picture in it. What I want to happen is when the users naturally migrate towards the bright colors on the screen in front of them and peck away at the mouse button, the values of the corresponding 3 columns are passed to the stored report and the report is ran and a PDF pops up and surprises the little buggers... sorry users that they actually managed to do something other than whine.
Ideas, any takers?
Maybe I will have to start a new thread with subject of
"PLZ HELP MZ URGENT!!!!!! PLZ PLZ "
or
"ORACLE IS STUPIDO!!!"
Those seems to get a lot of replies, some even helpful :)

Passing Parameters to a report by only knowing the rdf name fo the report

Hi all,
My requirement is that i konw the rdf name of a report and i want to call that report through form but i dont know the parameters in that report. Is there any way to find the parameters or any other method by which i can identify and pass the parametes to the report.
Thanks in advance

You don't have the rdf-files? Then i don't know of any way to find that out from the report itself (i guess you only have the rep-files?). Do you have any other forms-modules which already call the report? If so, you could check the calls there.

Discussion of ideas - passing parameters to a report

Guys,
I call a series of reports from my form and each report takes different parameters, these parameters are entered on the form then when the report is launched they are passed to the report. Rather standard and basic stuff.
However can people suggest how they would envisage the problem of some reports requiring more or less parameters than others? (I can easily send all the parameters and the report just use which ones it needs). But if someone can think of a way in which I could somehow hide the unneccessary text items? Ensuring only the text items which relate to parameters required by the selected report are displayed this would be much appreciated.
Thanks!

I totally agree with Ino Laurensse idea of designing tables to store Reports and Reports parameters :
2 tables is sufficient :
Tab_Reports : /* Defines all reports */
Report_Id Varchar2(30) Not Null PK
Report_Desc Varchar2(255);
Report_Params /* All parameters associated with the reports */
Report_Id Varchar2(30) Not Null PK References Tab_Reports (Report_Id)
Parameter1_Text Varchar2(30) /* Labael of Parameter */
Parameter1_Type Varchar2(20) /* Type of Parameter- Varchar, Date, Number etc */
Parameter1_Default Varchar2(255) /* To store any default values */
Parameter1_Mandatory Varchar2(1) /* Indicates if Parameter value is mandatory or not
Parameter50_Text Varchar2(30) /* Labael of Parameter */
Parameter50_Type Varchar2(20) /* Type of Parameter- Varchar, Date, Number etc */
Parameter50_Default Varchar2(255) /* To store any default values */
Parameter50_Mandatory Varchar2(1) /* Indicates if Parameter value is mandatory or not
NOTE :- The maximum Number of parameters to be set up depends upon the application. You
will be in a better position to decide.
All you have to do is the following :
1. Define 2 Blocks within you form based on the above 2 blocks
2. Query all records from table : Tab_Reports
3. Double-Click on Report_Id should :
3a. Pop up a window
3b. Pop up window block has base table associated with child table : Report_Params
3c. Report_Param is queried based on Reporet_Id Selected on the table : Tab_Reports
3d. Use a Non-Database Text Item to enter the Parameter Value in block Report_Params
NOTE :- You can set up Master-Detail Relation if you want to
3d. In relavant trigger all you have to do is :
3d1. Use Set_Item_Property to Non-Db Column to set the column data type, Mandatory and
Initial Value of the parameter column
This method, Let ORACLE forms do all validations. You don't have to worry about it.
4. To Call reports with appropriate Parameters :
4a. All you have to do is Loop through the Block and use Add_Parameter to the Parameter List
before using the bult-in to call the report module.
Whenever a new report is created, all you have to do is :
1. Create a new entry in table : Tab_Reports
2. Buld up the associated parameters table : Rep_Params

Passing parameters to the reports server

Query on passing parameter from URL to the report server and then to the graphic report builder. We are able to pass the parameter from URL to the report server but we don't know the way of passing this parameter from report server to the graphic bulder or

the graphic builder.

Can you tell me how to pass parameters to report server within URL.Thanks!

Passing Parameters to Crystal Report

Dear all,
I wonder if anybody has tried out the crystal report bundled with workshop
in SP2.
I got some problems when I try to pass a parameter from a jsp in workshop to
crystal report according to part 4 of tutorial in the Crystal Reports for
BEA Weblogic workshop Developer's guide.
This message show in the web browser:
com.crystaldecisions.report.web.viewer.CrystalReportViewer
Some parameters are missing values
However, the report viewer works fine in workshop if I am not passing
parameters.
If anyone has successfully setup a report which involves parameter passing
in workshop, I would appreciate you can share the tricks how to make it
work.
Thanks!

Challenge passing parameters to discoverer report

Hello everyone, I am following the instructions on this website - http://learndiscoverer.blogspot.com/2008/11/metalink-note-304192.html
Basically, we want to use parameters for discoverer reports, especially date parameters because of some performance issues we have been having with discoverer.
Here is the process I am using. Please correct me if I am doing anythinng wrong.
1. Login to apps schema and create context
CREATE OR REPLACE CONTEXT DISCO_CONTEXT
USING EUL4_US.DISCO_PKG
2. Login to eul4_us schema and create package
CREATE OR REPLACE PACKAGE DISCO_PKG
AS
FUNCTION set_context(p_name VARCHAR2,
p_value VARCHAR2) RETURN VARCHAR2;
FUNCTION show_context(p_name VARCHAR2) RETURN VARCHAR2;
END disco_pkg;
CREATE OR REPLACE PACKAGE BODY DISCO_PKG
AS
FUNCTION set_context(p_name VARCHAR2,
p_value VARCHAR2) RETURN VARCHAR2
IS
BEGIN
dbms_session.set_context('DISCO_CONTEXT', p_name, p_value);
RETURN p_value;
END set_context;
FUNCTION show_context(p_name VARCHAR2) RETURN VARCHAR2
IS
BEGIN
RETURN SYS_CONTEXT('DISCO_CONTEXT', p_name);
END show_context;
END disco_pkg;
Then grant access to apps
GRANT ALL ON DISCO_PKG TO APPS;
Then import the functions show_context and set_context into discoverer
3. Go back to apps schema and create synonym
CREATE PUBLIC SYNONYM DISCO_PKG FOR EUL4_US.DISCO_PKG;
4. Create discoverer custom folder using the following query:
SELECT DISTINCT
pet.run_result_id
,papf.employee_number
FROM
per_all_people_f papf,
--hr_lookups hl,*
per_all_assignments_f paaf,
hr_all_organization_units haou,
per_jobs pj,
per_grades pg,
pay_people_groups ppg,
--per_addresses pa,*
--hr_locations_all hla,*
per_positions pps,
per_people_f ppf,
pay_assignment_actions paa,
pay_payroll_actions ppa,
PAY_RUN_RESULTS_V pet,
--pay_element_types_v1 pet,
pay_all_payrolls_f papaf
WHERE
papf.person_id=paaf.person_id
AND papf.employee_number=ppf.employee_number
AND paaf.organization_id=haou.organization_id
AND paaf.job_id=pj.job_id(+)
AND paaf.grade_id=pg.grade_id(+)
AND paaf.people_group_id=ppg.people_group_id(+)
AND paaf.position_id=pps.position_id(+)
AND paaf.business_group_id=0
AND paa.assignment_id = paaf.assignment_id
AND paa.payroll_action_id = ppa.payroll_action_id
AND paa.assignment_action_id=pet.assignment_action_id
AND paaf.payroll_id=papaf.payroll_id
AND ppa.effective_date BETWEEN paaf.effective_start_date AND paaf.effective_end_date
AND ppa.effective_date BETWEEN papf.effective_start_date AND papf.effective_end_date
AND ppa.action_type ='R'
AND ppa.action_status = 'C'
AND paaf.assignment_type = 'E'
AND paaf.primary_flag = 'Y'
AND haou.business_group_id=0
AND ppa.effective_date = TO_DATE(SYS_CONTEXT('DISCO_CONTEXT','PAYROLL_DATE'))
5. Create a parameter called Payroll Date. Default value is set to NULL and the "Create Condition" checkbox is unchecked.
6. Create a calculation
SET_CONTEXT('PAYROLL_DATE', TO_CHAR(:Payroll Date))
And that's it.
The thing is, this doesn't work for me.
But for the same query, if I enter the date value I am substituting, values show up. So it seems for some reason, the context value probably isn't being set or thereabouts.
I have tried setting the context manually in a TOAD session using:
declare
v_ret varchar2(50);
begin
--dbms_session.set_context('DISCO_CONTEXT', 'PAYROLL_DATE', '31-MAR-2010');
v_ret := disco_pkg.set_context('PAYROLL_DATE', '01-MAR-2010');
dbms_output.put_line(v_ret);
end;
And afterwards run the query:
select sys_context('DISCO_CONTEXT', 'PAYROLL_DATE') from dual
And results do show up here. So I'm wondering what could be wrong.
Please help.

Hi ,
Are you saying I should create a new workbook that is not based on my custom folder for setting and showing the context value? You don't need to create a new workbook, you can just create a new worksheet in your report workbook, but you will need two sheets to use contexts. The sheet that sets the contexts should not be based on your custom folder, but on a folder that returns a single row. You cannot set and check contexts in a single SQL statement, so you have to have 2 worksheets.
You can default the contexts using a trigger or initialisation SQL so that the user only has to set the contexts if they are not using the defaults.
