Passing Parameters to Discoverer report from ORacle Forms

Hi All,
Can I pass a value to a parameter defined in the discoverer page from a D2k form? I want to call a discovere page from fmb while passing a parameter.
This is extremely urgent for me. Pl help .
Thank you and Regards,
Vaibhav M. Shah.

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.

How to invoke crystal reports from Oracle forms 11g R2 along with passing p

How to invoke crystal reports from Oracle forms 11g R2 along with passing parameter to it.
how to pass parameters to crystal report, please help.

how to pass parameters to crystal report, please help.This would entirely depend on crystal reports and you might find informations on crystal reports related communities more likely...I for one have seen crystal reports the last time about 12 years ago. And even back then I simply acknowledged it's existence instead of working with it.
Maybe crystal reports can be invoked via a URL call which would make it simple as you'd need simply build an URL and show the report using web.show_document. But that's pure speculation. Also you might not be the first with this requirement, so the solution to your problem might be right under your nose and just a little google search away ;)

Call Oreacle report from Oracle form

Hi,
I need call a Oracle report from Oracle Form and found the the following procedure from this forum. I have 2 parameters 'start_date' and 'end_date' passing to called report. The following example just have onle parameter
'departmentno' passing. Is that mean I need to call add_parameter twice like the following?
add_parameter(plid, ''start_date' , TEXT_PARAMETER,:control.start_date);
add_parameter(plid, ''end_date' , TEXT_PARAMETER,:control.end_date);
In the following example:
add_parameter(plid, 'departmentno', TEXT_PARAMETER,to_char(:dept.deptno));
Thanks for clarification!!

END IF;
/* if it does destroy it */
plid := create_parameter_list(the_param);
/* create it afresh */
add_parameter(plid, 'departmentno', TEXT_PARAMETER,to_char(:dept.deptno));

How to print BIP reports from Oracle Forms?

Hi all,
I have a question in regards to printing BIP reports from Oracle Forms... We are aiming for a server installation of BIP with integration to Oracle Forms using SSO to handle security. We use Forms built-in web.show_document to render and view the report in PDF/Excel etc... We would like to by pass the viewing and print some of these reports directly to the printer.
Any idea/suggestions how we can go about this?
Thanks in advance for your time.
Yahya

Yahya,
via HTTP it's not possible to send a report directly to the printer. You had to go via the Scheduler, which is able to do that. With the WebService API you can call a report with the Scheduler and Execute Immediate.

Rainer

Set_Application_Property(Cursor_Style,'DEFAULT');
END;NOTE: Change the report name and path according to your required file name and path in
the "Crystal_CrystalCtrl.ReportFileName" method call. Also, the connection string shown
assumes that you will use the current USER and PASSWORD for the Form.
- To make the above Form generic so that you can run any Crystal report from it, then create
a parameter for the report name and pass it to the Form using CALL_FORM from any other Form.
Then just replace the file name with the passed parameter.
-. Run the Form
If its correct/helpful please mark it thanks.

Hi,
You have to have the report server
a. Installed and configured
b. Running.
See
http://docs.oracle.com/cd/E21764_01/bi.1111/b32121/pbr_strt001.htm

http://docs.oracle.com/cd/E17904_01/bi.1111/b32121/pbr_conf003.htm#i1007341
If you are using rwservlet then you will find the name from the Configuration file referred to in the last link.

Calling Report From Oracle Forms

Hi
I am calling this one report from oracle forms, I am using global temporary table to run that report. I am first inserting data into the temporary table through oracle form and then i am calling report in that form to view the data in that temporary table. The problem is, we can not view the data of an other session if we are using temporary table. When i call report from that form a new session get created due to which i can not see the data. Is there any method of calling report from oracle form that a same session is used to run the report?
Thanks.

As you mention Forms and Reports do not share the database session. I had the same problem and resolved it using record groups and DATA_PARAMETER to transfer data from Forms to Reports. You could also read the Note 110495.1 on Metalink to find useful information regarding this issue.

How to Call a jasper report from Oracle Forms 6i.

Hi
Can anybody tel me how to Call a jasper report from ORacle Forms 6i.
Thanks & Regards
Bango

Forms 6i client/server? Use the HOST command to call the report. Since a Jasper report is just a call to a url, it will be something like:
v_url := '<your url to the report>';
host ('cmd /c start '||v_url);If it's web Forms 6i it even easier. Just use web.show_document(<url>).

Calling Crystal Reports from Oracle Forms 10G

Hi everyone,
I am trying to call a crystal report from Oracle Forms 10G.
I have a button on my Form which when clicked calls a Crystal Report which the uaser then wants to save as a PDf file.
Can someone please send me the code to do this and also the exact steps that are to be followed.
Thanks
Fm.

Hi Andreas,
I am trying to call the crystal report from an Oracle Form using a URL. No batch file is being used here.
I am looking for a peice of code similar to run_product or run_report built in in Oracle which calls an Oracle report from an Oracle Form.
Also I dont want to display the report on a screen or a window in Oracle Forms. I would like it to run just as we run an Oracle Report from an Oracle Form.
Is that possible ? If yes please let me know the steps to do this.
Thanks

Calling reports from oracle forms 9i

Hi
I succeded to call reports from oracle forms but for I have a problem for only one report so I can't call it. this a part of the code I'm using :
declare
     pl_id2 ParamList;
     pl_name2 VARCHAR2(30) := 'liste2';
v_rep VARCHAR2(100);
     rep_status VARCHAR2(20);
begin
pl_id2 := get_parameter_list(pl_name2);
if (Id_Null(pl_id2) )THEN
pl_id2 := Create_Parameter_List(pl_name2);
IF NOT Id_Null(pl_id2) THEN
     add_parameter(pl_id2,'mois',TEXT_PARAMETER,:mois);
END IF;
end if;
IF NOT Id_Null(pl_id2) THEN
if(:mois is not null) then
v_rep := RUN_REPORT_OBJECT('My_report',pl_id2);
message(v_rep);
rep_status := REPORT_OBJECT_STATUS(v_rep);
WHILE rep_status in ('RUNNING','OPENING_REPORT','ENQUEUED') LOOP
rep_status := report_object_status(v_rep);
END LOOP;
IF rep_status = 'FINISHED' THEN
WEB.SHOW_DOCUMENT('/reports/rwservlet/getjobid'||substr(v_rep,instr(v_rep,'_',-1)+1)||'?'||'server=repserver','_blank');
ELSE
message('Error when running report');
END IF;
end;
the problem I've remarqued is that the function message(v_rep) is always returning the value :'repserver_0'.
so when I execute the previous code I'm getting the 2 messages : 'repserver_0' and 'Error when running report'.
Rq: the report my_report is running very well in report builder.
does someone see where is the problem so can help me??
thanx.

Hi,
This usually happens when the report fails on the report server. To obtain details on why a particular report has failed, use the showjobs page :
http://server.domain:PORT/reports/rwservlet/showjobs?server=repserver
and check the detailed error occured.
This is logged as Bug:3017948. It is marked to be fixed in version 9.0.4 (Reports 10g) and also has one-off patches for version 9.0.2.3 on Windows platforms. If you need further assistance about patches, please raise a Service Request (SR) with Support via Metalink (http://metalink.oracle.com).

Is it possible to call a Crystal Report from Oracle Forms.

Hi Everybody,
I got a Dout about Crystal Reports. Is it possible to call Crystal Reports from Oracle Forms.

Hello,
That depends are you running Forms via the WEB or client/server. I will assume you are running client/server since you are running crystal reports. The answer is yes. All you will have to do is use the HOST command or the win_api_shell to run the report. Look in the Forms manual for information on the commands and what else you may need.

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.
