Using "and","or"(eg Anand Y) as parameter values to BI Publisher reports

I'm trying to pass a name parameter containing "and" for eg Anand Y, This value does not get passed to the report.Log reports invalid parameter value.
Has any one faced this issue before?

Rainer,
Thanks for your reply. It helped me work around seeing the Adobe error message.
Like you suggested I changed the report query attributes to use the ADVANCED xml-structure property (so my xml file would not be empty).
Here is what my xml file looks like when the query returns no-data-found.
<?xml version="1.0" encoding="UTF-8"?>
<DOCUMENT>
<DATE>03-MAR-08</DATE>
<USER_NAME>TDIPPER</USER_NAME>
<APP_ID>750</APP_ID>
<APP_NAME>APEX - Application Builder</APP_NAME>
<TITLE>Monthly_Detail_Report</TITLE>
<P5_MONTH_FORMATTED>2008 February</P5_MONTH_FORMATTED>
<REGION ID="0">ORA-01403: no data found
</REGION>
</DOCUMENT>
Here is what my xml file looks like when the query returns data. For this example I've removed most the data... I just want to show my structure.
<?xml version="1.0" encoding="UTF-8"?>
<DOCUMENT>
<DATE>03-MAR-08</DATE>
<USER_NAME>TDIPPER</USER_NAME>
<APP_ID>750</APP_ID>
<APP_NAME>APEX - Application Builder</APP_NAME>
<TITLE>Monthly_Detail_Report</TITLE>
<P5_MONTH_FORMATTED>2008 January </P5_MONTH_FORMATTED>
<REGION ID="0">
<ROWSET>
<ROW>
<POSTING_MONTH>01-JAN-08</POSTING_MONTH>
</ROW>
In the rtf template like you suggested I added conditional logic to show a no-data-found message else show the contents of my report. The key idea here is that if ROW (holds the data) is defined in the xml structure then there is data returned from the query else I show the no data message.
<?if:not(ROW)?>
No Data Found For Specified Search Criteria.
<?end if?>
<?if: (ROW)?>
...detail of my report is here...
<?end if?>
Thanks for your help in resolving the issue. I do prefer to have Oracle fix the issue of showing the Adobe error when report queries don't find data, but this is a good work around until something better comes along.
Thanks,
Todd

Fetch table value in BEX Web report using Javascripts, and assign condition

Hi Gurus,
I am currently using WAD 3.5. I need to change the web report to behave like below :-
1. Default layout (Field A B C) with condition A & B activated.
2. If the drilldown Field B and C is removed, leaving only field B alone in the report drilldown, deactivate condition A & B, Activate condition C & D.
3. the above can be reversed where user drilldown field B & C into the layout, the condition A & B need to then be activated back.
So I believe this can be done using Javascript. So my questions are below
1.) How do i fetch table value for the navigationblock ? with navigationblock i am able to know what are the columns are in the drilldown (i will not display free characteristics, so ignore this part). how do i read the content of NAVIGATIONBLOCK_1 as shown in following code? using javascript.
<object>
 <param name="OWNER" value="SAP_BW"/>
 <param name="CMD" value="GET_ITEM"/>
 <param name="NAME" value="NAVIGATIONBLOCK_1"/>
 <param name="ITEM_CLASS" value="CL_RSR_WWW_ITEM_NAV_BLOCK"/>
 <param name="DATA_PROVIDER" value="DATAPROVIDER_1"/>
 <param name="SHOW_FREE_CHARACTERISTICS" value=""/>
 <param name="SHOW_NAVIGATION_ICONS" value=""/>
 <param name="SHOW_FILTER_ICONS" value=""/>
 ITEM: NAVIGATIONBLOCK_1
</object>
2.) After question 1.) is done, please advice how do i activate/deactivate the conditions? based on the fields found in above. Maybe I can use IF navigationblock_1 contain field A only, then set condition A & B , etc.
<object>
 <param name="OWNER" value="SAP_BW"/>
 <param name="CMD" value="GET_ITEM"/>
 <param name="NAME" value="CONDITIONLIST_1"/>
 <param name="ITEM_CLASS" value="CL_RSR_WWW_ITEM_CONDITION"/>
 <param name="DATA_PROVIDER" value="DATAPROVIDER_1"/>
 ITEM: CONDITIONLIST_1
</object>
I would appreciate if we can solve Question 1 first before proceed to 2.)
Please advise. Thanks

Hi JTi,
what i have understood from your requirement is that you want to access the web item table_1 in javascript, you can get that as below:
Add

tag before your web item and set its id to table.

<param name="OWNER" value="SAP_BW"/>
<param name="CMD" value="GET_ITEM"/>
<param name="NAME" value="TABLE_1"/>
<param name="ITEM_CLASS" value="CL_RSR_WWW_ITEM_GRID"/>
<param name="DATA_PROVIDER" value="DATAPROVIDER_1"/>
<param name="GENERATE_CAPTION" value=""/>
<param name="CAPTION" value="jezel"/>
<param name="ONLY_HIERARCHY_NAVIGATION" value="X"/>
<param name="BLOCK_SIZE" value="0"/>
<param name="SHOW_PAGING_AREA_BOTTOM" value=""/>
ITEM: TABLE_1

In javascript access it as :
var mytable = document.getElementsById("table");
Hope this helps
Thanks

Missing parameter values message when exporting report

Post Author: Gr_Pr
CA Forum: .NET
Using .NET 2005, CR XI R2, and the Crystal SDK for .NET 2005 to generate reports. Basically CR is my application's reporting tool. So, we create a report in CR XI R2, then distribute that report to our users loading it into the .NET application using the Report Document class.
We have a small problem.
Our user's have the ability to use pre-defined 'prompts' that will pass parameters to the reports. Let's say that the prompt will pass in (5) pre-defined parameter values, but the customer wants to run their own 'custom' report using our prompt, but their 'custom' report contains (6) parameters.
If I let the Report Viewer load the report, the user will be prompted for the missing parameter value that was not supplied by the 'prompt'.
If I run the report without loading it into the Viewer and try to export the report directly to PDF I receive an error message from CR stating I have 'Missing Parameter Values' then the report errors out.
Has anyone come across this? Is there something I missed?
I am not real sure as to why you would be prompted by the Viewer and not by the Export Class. This worked fine when using the RDC component, I was prompted for the missing parameter value by both options.
Any help would be greatly appreciated.

Hi,
The report has it's own ADO Datasource set in crystal reports, so I just pass the log on information to the report object before doing anything else.
this.DataSourceConnections[0].SetConnection("ServerName", "Database", "sa", "Password");
I then do a refresh before applying the parameter values (I do this because the user can preview the report more than one time by using a preview button on the parameter form without re-loading the report object)
this.Refresh();
Then I set all parameter values followed by setting the recordselection formula.

How to suppress "enter parameter values" screen in crystal reports for Visu

Hi,
    I am passing parameters to the report through program. But still the "Enter Parameter Values" Dialog is shown every time I run the application. Code used to pass parameters is given below:

Missing Parameter Values while using Change SubReport links

Hi,
I am using Change SubReport Links to pass data from Main Report to the SubReport. The report works fine at design time when I preview it, but at runtime I get "Missing Parameter Values" error.

How to set item values without using fields in branch's ACTION block?

Okay, I will try to say this in a easy way so it is not weird.
I have created a button, SAVE, that has a Branch of branch type: Branch To Function Returning A Page. This is my code for the branch:
if :P2008_NAP_SUPPORTING_MATERIALS = 'Yes' then
return '2092';
else
return '2040';
end if;
The code for this type of branch is stored in the ACTION block of the Branch page. The ACTION block for a Branch of branch type: Branch To Function Returning A Page is different than the ACTION block for a Branch of branch type: Branch To Page Or URL.
I need to set some item values with some specific values, which I can do with a branch type: Branch To Page Or URL. This is not possible with the branch type: Branch To Function Returning A Page. The ACTION block is totally different.
How can I set some values on say Page 2040 from Page 2008 without using fields in the branch's ACTION block?
Thank you in advance,
Maggie

Andy and Scott,
I love seeing different perspectives in solving problems, it opens my eyes to new ways of looking at/using the tools (reserved words and 'Function returning a Page', etc.).
One of my pet peeves has been that on branches I was limited to only 10 variables to be passed (I know, who would want more - but there was an instance where I had to pass more), and an even more frustrating time when using report Column Linking, which limits me to 3 variables.
At least with the Branch linking I can use your suggestion Andy and add the variable setting statements into the function. I am assuming of course (and I should be able to) that I will be able to set more that 10 variables in a IF condition prior to the RETURN statement. This method will be much more understandable, for me, when looking through the branch at a later time to see what is happening, than an URL link where all the variable are strung out 'in a line' so to speak.
I will still need to use URL Target branching on Links contained within a Column Attribute when I need to pass more than 3 variables, of which I have several places where I do this.

Large Number of Multi-Select Parameter Values does not generate Report

I have a SSRS Report that requires 4 multi-select parameters.
The report is deployed on a SharePoint website with SSRS integration.
I calculated, if the user selects 'Select All' for one specific customer, there could be at most 2700 possible parameter values among the 4 parameters.
In some cases, when a user selects 'Select All' and clicks Apply, nothing happens. No icon showing Processing Report.
If a user selects 'Select All' and the total number parameter values are under 500 for a specific customer, there is an icon showing Processing Report.
I followed the instructions at:
http://social.msdn.microsoft.com/Forums/en-US/b02ccb5d-6019-4d63-bd6c-8baff24fffd8/sql-server-limit-on-the-number-of-multivalue-parameter-selections?forum=sqlreportingservices
That did not help.

Why are my parameter values not setting in report?

G'day,
Like many others I am a developer who is new to crystal reports. I have researched a lot for setting report parameters and although my code seem to be working when I open the report through code I'm always asked to re-enter the parameter values.
Here is my code:
behind button event
PersonalAttendance myReport = new PersonalAttendance();
ReportUtility ru = new ReportUtility();
ru.SetReportParameter(myReport, "reportName","the title");
myReport.Refresh();
myReport.SetDataSource([a data source]);
ReportViewer.ReportSource = myReport;
method behind custom class "ReportUtility()"
public void SetReportParameter(ReportClass rc, string FieldName, object parameterValue)
//Get the collection of parameters from the report
crParameterFieldDefinitions = rc.DataDefinition.ParameterFields;
//Access the specified parameter from the collection
crParameterFieldDefinition = crParameterFieldDefinitions[FieldName];
//Get the current values from the parameter field. At this point
//there are zero values set.
crParameterValues = crParameterFieldDefinition.CurrentValues;
//Set the current values for the parameter field
crParameterDiscreteValue = new ParameterDiscreteValue();
crParameterDiscreteValue.Value = parameterValue;
//Add the first current value for the parameter field
crParameterValues.Add(crParameterDiscreteValue);
//All current parameter values must be applied for the parameter field.
crParameterFieldDefinition.ApplyCurrentValues(crParameterValues);
I'd really appreciate any assistance....
Cheers,
Brendan

Help on using AWR report

we use ORACLE 11.1.0.7. We have couple of processes that run for about 2 to 3 hours which are scheduled to run after 6 pm. When these processes run, currently users are not allowed to access the system . So last week we ran these processes with 30 to 40 users in a test instance, basically reading data.I have preserved the AWR snapshot during these processes. we have the preserved the AWR snapshots during the processes when users are no allowed in the system. I believe we can compare two periods in Grid. I would like to know what information would be helpful from this report?

I would like to know what information would be helpful from this report?That would entirely depend on why you generated the AWR reports in first place - what was your motive, what were you looking for, were there any major wait events etc.

Max value without using max() function

Hi
Is there any way to get the max value from a table without using MAX() function
Thanks

well if you think about it i'm sure you'll find a solution
what does max(field) means, it simply is the value of the field where no other value of the same field that is > than this value exists.
consider the following :
table TAB(
fld NUMBER(5));
translate the logic and you'll have
select a.fld from TAB a where NOT EXISTS(select b.fld from TAB b where b.fld>a.fld) and rownum=1;
of course there are better ways i'm sure, you'll just have to figure'em out.

Function that returns N values, without using a string

Hi, how can i make a function that returns several valures (that hasn't a exact number of returned values, it could return 3 values, or 7) without using a string?
When i need to return several values from a function, i put the values inside a varchar like thus 'XXX,YYY,ZZZ' and so on. Don't know if this has a poor performance.
If you can supply simple examples for what im asking, i would be nice.
(without using a string)

Can i create the type objects inside a package? If i
can, they will be local to the package, right?Yes, you're right.
Pipeline returns a row or several?You can use pipelined function in the same way you use table:
SELECT * FROM TABLE(pipelined_funct(agr1, agr2));
It returns results as separate rows.

Passing multiple parameter values to a detail report. How?

Help!
I have a Summary report and a Detail report.
Summary report has a parameter that may have multiple values (ie returning an array).
I need to pass these values to the Detail report.
Anybody has managed to do it?
Thanks in advance...
Inga

Thank you for your reply Sunil...
The problem is as follows:
I have a report portlet that has a parameter with multiple values. Ie I would have two status values passed into this Summary report that shows, say total sum for those statuses. I have a link from this report to a detail report, and i need to pass both of these values into the detail report.
I have tried adding a parameter (p_status_param) in the SQL query that would be a part of link by building it in "PL/SQL after header section" and doing the parameter replace.
SQL query:
select
'<a href="./RTS.RPT_OPEN_CALLS_BY_ASSIGNEE_01.SHOW?p_arg_names=p_assigned_user_id&p_arg_values='||cr.assigned_user_id||''||:p_status_param||'''>'||s.user_name||'</a>' full_name,
cr.assigned_user_id,
count(*) total_calls
from
trts_call_request cr,
trts_security s
where
cr.assigned_user_id = s.user_id
and cr.current_status_id in :p_status
and cr.assigned_user_id in :p_assigned_user_id)
group by
s.user_name,
assigned_user_id
PL/SQL:
declare
 v_return varchar2(32767) := '';
begin
 for i in 1..l_arg_names.count loop
 if l_arg_names(i) = p_reference_path||'.p_status' then
 v_return := v_return || '&p_arg_names=p_status&p_arg_values='||l_arg_values(i);
 end if;
 end loop;
 myats30.wwv_name_value.replace_value(l_arg_names, l_arg_values, 'p_status_param',myats30.wwv_standard_util.string_to_table2(v_return) );
htp.p(v_return);
end;
However, when you run the report, this is what you get (see what the parameter has been replaced with):
ORA-00907: missing right parenthesis (WWV-11230)
Failed to parse as RTS - select '<a href=./RTS.RPT_OPEN_CALLS_BY_ASSIGNEE_01.SHOW?p_arg_names=p_assigned_user_id&p_arg_values='||cr.assigned_user_id||''|| ( :zz21, :zz22, :zz23 ) _param||''">'||s.user_name||'</a>' full_name, cr.assigned_user_id, count(*) total_calls from trts_call_request cr, trts_security s where cr.assigned_user_id = s.user_id and cr.current_status_id in ( :zz21, :zz22, :zz23 ) and cr.assigned_user_id in :p_assigned_user_id) group by s.user_name, assigned_user_id order by ASSIGNED_USER_ID ASC (WWV-08300)
Any ideas how I could build this link programatically???
Thank you...

Can I create a dynamic report in the server without using a report template

Hi,
My company just bought a Crystal Report Server XI and it didn't have a report designer.
I can't start creating report without the designer.
The question is can I generate a dynamic report at runtime (on the crystal report server ) without using report template?
My project requirement is to use a crystal report server to manage the reports.
Some client web application will just access this report server.
I hope the experts can provide me some guidance.
regards,
Rulix
Edited by: Rulix Batistil on Nov 3, 2008 8:08 AM

Hi Rulix,
The latest version of CR Server is 2008. Therefore I'm assuming you are using CR Server 2008.
New in CR 2008 is the .NET report modification software development kit (SDK). The report application server (RAS) SDK is now available for users of Crystal Reports .NET API without the use of a RAS server. Report modification such as changing, adding, or removing database providers, or adding, removing, or creating report objects, parameters, formulas, and sections can be achieved by accessing the RAS SDK through the Crystal Reports .NET SDK.
Java developers however receive the JRC and Java SDK documentation through the free Crystal Reports for Eclipse download. This product will be updated on a separate schedule from Crystal Reports.
Further Information and samples are available in our [Developer Library|https://www.sdn.sap.com/irj/sdn/businessobjects?rid=/webcontent/uuid/5001d5de-f867-2b10-00bf-8d27683c85a0]
