[Trouble] The Report has no tables

Hi there,
i have trouble in using Crystal Reports for .NET 2.0.
I load a CSV file via JetDB Provider as Text database and try to use it as DataSource for my report.
But it crashes all time, with a error like this "report has no tables".
Actually i dont really know Crystal Reports well, i got the project from an ex-employment from our Company.
Of course i readed the PDF documentations "Reporting Off ADO.NET Datasets", "Crystal Reports Guide To ADO.NET", "Connecting the Report Designer Component to a Data Source" but that didnt help me at all.
So i hope you guys can help me,
here are the code: http://rafb.net/p/hMon9Z65.html
with best regards,
Torsten Sailer

So if I understand correctly, you are loading data from a CSV file into a DataSet object and passing the DataSet to a report that you have loaded using the ReportDocument object? Are you using the SetDataSource() method to pass the DataSet to the report?
Make sure that the schema of the DataSet isn't changing from when you designed the report. The report's schema must match the DataSet schema when passing the DataSet to the report.
The best way to troubleshoot the issue is when the error occurs, write out the DataSet to an .xml file (with the schema) and then in a simple Windows app, load the same report, and the xml schema/data into a DataSet object (rather than the CSV) and see if the same error occurs. If it does, open the report in design and do a "Set Database Location" to your xml file and see if it picks up any changes. If it does, then that might be the reason why it errors....the schemas are not matching and you need you find out why.

[APEX 3] Requested source data of the report has been modified

Hello APEX-Friends,
I have a common problem but the situation is a bit different here. Many of you might know the "invalid set of rows requested the source data of the report has been modified" problem. Often it occurs on submit. That means, you have a report, you select rows, you do things, you submit the page and everything blews up.
This is because you enter some values into fields the report depends on and so you modify your report parameters and the source data changes.
But:
In my case I have a dynamically created report that blews up before any submits occur or values change.
My query is a union of two selects. Both query different views. Those views use a date field as parameter and some compare functions.
I read the field with a V-Function i wrapped arround the apex V Function - declared as deterministic. My date compare function is also declared deterministic (I doubt this makes any differences as it might be only important for the optimizer, but as long as I don't know exactly what APEX evaluates, I go for sure).
I ensured, that the date field is set by default with the current date (and that works, because my interactive report initially displays correct data from the current date).
So everything is deterministic and the query must return same results on subsequent calls, but APEX still throws this "source data has changed" error and I am to 99.99% sure, that this cannot be true.
And now the awesome thing about this:
If I change the value of the date field, an javascript performs a submit. The page is reloaded (without resetting pagination!) and everything works fine. I can leave the page, reenter, do things - everything works well.
But if I log into the application and directly move to the corrupted report and try to use the pagination without editing fields or submitting the page the error occurs.
Do you have any Idea what's happing there? I could try to workaround this by submitting the page the first time it's entered to trigger this "mystery submit" that gets everything working. But I would like to understand this issue and have a clean solution.
Thanks in advance,
Mike aka UniversE

Okay, I found a solution, but I do not understand it - it might be a design flaw in APEX.
I mentioned the date field that is used in the query. I also mentioned that it is set with the current date by default. I did not mention how.
There are some possibilities in APEX to do so.
1. Default-Setting in the element properties
2. Static assignment if no value is in session cache
3. Computation before header
I did the first and second.
BUT:
An interactive report seems to work as follows. A query is executed to get all rows of the report. Then a second query is executed to get the rows that shall be displayed. And the order is screwed up, I think.
1. The first report query to get all rows
2. The elements are loaded and set to default values
3. The second report query to get the display rows
And that's the reason why nothing worked. Scince I added a computation before header the date field is set before the report queries are executed and everything works all fine now.
But I think it's a design flaw. Either both queries shall be executed before Regions or afterwards but not split as field values might change when elements are loaded.

How to know the report has already been sent to printer?

Dear All,
I have one problem to check that the report has been printed on paper through a printer after user already previewed and pressed Printer button. Is there any parameter will be sent back from system to inform the program? Please suggest me if you have developed or solved this problem.
Thank you in advance.

Yes. I ran the code example and it ran successfully.
So if we wanna generate report by java code, we should use the code as a http client to access report server to do it.
I think we could use url http://server:port/reports/rwservlet/showjobid to know the status of generating report (i.e. successful or failed).
And one more question is that could I get the jobid by any url as soon as I generate my report?
Thanks a lot.
Best Regards.

Table which contains name of the report generated from table

Hello everyone,
Is there any table which stores the report names that are created from table.
For example if my table name is 'ABC' a new report will be created for table at run time '/1BCDWB/DB/ABC'.
I also need to have table names, which stored the values when a layout is changed
For example if I have ten fields in my table, first time ill choose 5 fields, second time ill change the layout and choose 10 fields and ill save the layout.
If any Function modules are there please let me know
Please let me know, if anyone has details.
Thanks,
Gayatri.

How to verify that the user has changed table row data before db update

Hi all,
Iam using Oracle ADF with EJBs.
I have a single selection table that displays rows of data returned from a function of my data control.
The columns of my table are editable so that the user can change the data. The user selects a row, changes the data in one or more columns of the row and saves the data by means of a submit button. The code in the submit button, identifies the row of the corresponding iterator that the user clicked on and updates the data in the database (using the 'mergeEntity' function of the EntityManager)
Before saving the data, I want to put some logic to check whether the user has actually changed some data to avoid unnecessary updates in the database . But for this I need a technique to detect that the user has indeed changed some data in the table row.
One technique I have been using so far was to isolate the iterator row of the table and then query the corresponding row in the database table and compare their values.
Except from dummy, this technique is not efficient if the table contains many rows.
Moreover, in my case I have observed that on successive updates on the same row , the query on the database returns the new values (user changed values) and not the actual values contained in the database table. This means that when the user updates an iterator row the cached data affect also the results of the SELECT statement from the actual database table!!! Isn't this strange ?
Can somebody propose me a neat method to detect when the user has changed the the data of an iterator row ?

Hey Alan,
The below solution seems overly complicated to me and can not be implemented without a custom screen and/or the use of JavaScript. Also, if your main concern is that a user may accidentally loose all their data because they closed the browser window or the session times out before they hit the save button then this solution does not help you.
There are a couple of simpler approaches you can take here:
# If the use of JavaScript is permissible you can hook into the windows 'onUnload' event, and pop-up a message box which gives the user the opportunity to cancel closing the window and save their case if they haven't already.
# Implement an autosave feature by hooking into one of events provided by web determinations. A simple (but rather naive) way of doing this would be to hook into the OnRenderScreenEvent and call save on the interview session every time the event fires. This guarantees that all the data the user has submitted will aways automatically be saved, thereby removing the need to make sure the user manually saves their data before closing the browser.
Automatically making Web Determinations close a browser window has to be done using JavaScript. However, doing so means that a) it won't work for people who turn off JavaScript, which is commonly done for accessibility reasons b) you'll likely run afoul of the browser's security mechanism (they generally won't let you close a window that you didn't open and some really don't like you doing that at all).
Thanks,

The report has user profile dependencies when enabling caching.

Hi,
Using SQL Server Reporting Services 2008 R2.
I am getting the error in the subject trying to cache a report, I see that this is described here
http://social.msdn.microsoft.com/Forums/en-US/sqlreportingservices/thread/e2ce8dd0-17db-47de-b13e-3574cc9d536f
But, how does this solve my problem? I still want to use the user as a parameter filter so surely returning a default user as part of the error handling will just give every user the data for that hardcoded user when the report is run?
Sorry for my confusion
Many thanks

Hi ReportCreator,
When we use the User!UserID to filter the data at runtime, the system tries to evaluate the User during Cache Load. At cache time report processing does not have access to the user profile information. Any expression like User!... will cause “has user profile
dependencies” error.
Just as Jerry said, we can write custom code to call the User!UserID in your report to get rid of the UserID during the Caching Operation. Please note that we should use a valid filter instead of "System" like shown in the code to the filter the user.
If there are any other questions, please feel free to ask.

How to display a Report 9i from Forms if the Report has a Parameter Form?

Hi,
could some one please post me a code sample to show how to call a (paper layout, RDF) Report from Forms if I would like it to display the Report's parameter form first?
Thank you in advance.
Tamas Szecsy
I used the following code segment do achieve the job, but I get "REP-546: Warning: The value of restricted LOV parameter P_ALAL is not among the selectable values" message, even though I would like to specify the P_ALAL value on the report's parameter Form.
declare
paramlist_id ParamList;
tmp_riport_name varchar2(200);
report_id          report_object;
report_job_id varchar2(200);
tmp_id number;
begin
-- init
tmp_riport_name := null;
          -- parameter list
paramlist_id := get_parameter_list('mytmp_params');
if not id_null(paramlist_id) then
destroy_parameter_list(paramlist_id);
end if;
paramlist_id := Create_Parameter_List('mytmp_params');
add_parameter( paramlist_id, 'PARAMFORM', TEXT_PARAMETER, 'YES' );
          -- call report
report_id := find_report_object( 'DUMMY' );
if report_id.id is null then
     return;
end if;
-- display
set_report_object_property( report_id, report_execution_mode, runtime );
set_report_object_property( report_id, report_comm_mode, synchronous );
set_report_object_property( report_id, report_destype, 'preview' );
set_report_object_property( report_id, report_desformat, 'PDF' );
set_report_object_property( report_id, report_server, 'rep_geoias' );
     set_report_object_property( report_id, report_filename, :ALAP_REPORTS_NAME||'.rep' );
report_job_id := run_report_object( report_id, paramlist_id );
tmp_id := to_number(substr( report_job_id, length(name_in('rep_geoias'))+2 ));
web.show_document( '/reports/rwservlet/getjobid'||tmp_id||'?server=rep_geoias', '_blank' );
END;

I think you specified report object name incorrect.
in command line:
repid := FIND_REPORT_OBJECT('REPORT1');
Report1 must be name of report object in Form Builder.
However to call report from Oracle Form you must do more work. For example:
- Create report server name
- Adding some code to set property for report object base on report server you created.
Cheer!

How Many times the report has run

we created a solution that reads the information from STAT and stores it in a custom table for later retreival. we can then more closely monitor the amount of statistics kept without basis involvement. the function module to read the STAT information is:
call function 'SAPWL_STATREC_READ_FILE'
       destination servers-rfcdest
       exporting
            read_client                 = sy-mandt
            read_end_date               = pstop
            read_end_time               = pstopt
            read_exclude_username       = 'SAPSYS'
            read_start_date             = pstart
            read_start_time             = pstartt
       tables
            v2_normal_records           = stats
       exceptions
            wrong_parameter_combination = 1
            others                      = 2.
it takes some time to develop history, but we can now go back over a year to look at run time and execution trends by program, both ours and SAPs.

REP-0002: Unable to retrieve a string from the Report Builder message file;

Hi,
I've a custom report in which i need to display a large string, of more than 4000 characters. To cater to this requirement i've written a formula column which displays string upto 4k characters and for a string of size beyond 4k i am calling a procedure which uses a temp table having a clob field.
For a small string the report runs fine but whenever a large string requirement comes into the picture, said procedure gets triggered and i get REP-0002: Unable to retrieve a string from the Report Builder message file.
OPP log for the same gives an output as under:

Problem Description
When running a *.REP generated report file you get errors:
REP-00002 Unable to retrieve string from message file
REP-01439 Cannot compile program since this is a runtime report
Running the same report using the *.RDF file is successful.
You are running the report with a stored procedure,
OR you are running against an Oracle instance other than the one developed on,
Or, you recently upgraded your Oracle Server.
Solution Description
1) Check that the user running the report has execute permissions on any stored
SQL procedures called. <Note:1049458.6>
2) Run the report as an .RDF not an .REP , that is remove or rename the .REP
version of the report. <Note:1012546.7>

[Forum FAQ] How do I send an email to users when the data in the report have been changed in Reporting Services?

Introduction
There is a scenario that the data in the report changes infrequently, so the users want to be informed and get the most updated data once the data changes. By default, report server always run the report with the most recent data. Is there a way that we
can subscribe the report, so that we can send an email to users when the data in the report has been changed?
Solution
To achieve this requirement, we can create a subscription for the report, then create a trigger in the table which including the report data. When this table has data insert, update or delete, it will be triggered and execute the subscription to send email
to users.
In the Report Manager, create a subscription for the report and make it only execute one time.
When we create a subscription, a corresponding SQL Agent job will be created. Then we can use the query below to find out the job based on ScheduleId:
-- List all SSRS subscriptions
USE [ReportServer]; -- You may change the database name.
GO
SELECT USR.UserName AS SubscriptionOwner
      ,SUB.ModifiedDate
      ,SUB.[Description]
      ,SUB.EventType
      ,SUB.DeliveryExtension
      ,SUB.LastStatus
      ,SUB.LastRunTime
      ,SCH.NextRunTime
      ,SCH.Name AS ScheduleName
          ,RS.ScheduleId
      ,CAT.[Path] AS ReportPath
      ,CAT.[Description] AS ReportDescription
FROM dbo.Subscriptions AS SUB
     INNER JOIN dbo.Users AS USR
         ON SUB.OwnerID = USR.UserID
     INNER JOIN dbo.[Catalog] AS CAT
         ON SUB.Report_OID = CAT.ItemID
     INNER JOIN dbo.ReportSchedule AS RS
         ON SUB.Report_OID = RS.ReportID
            AND SUB.SubscriptionID = RS.SubscriptionID
     INNER JOIN dbo.Schedule AS SCH
         ON RS.ScheduleID = SCH.ScheduleID
ORDER BY USR.UserName
       ,SUB.ModifiedDate ;
Create a trigger in the table which including the report data.
CREATE TRIGGER reminder
ON test.dbo.users
AFTER INSERT, UPDATE, DELETE
AS
exec [ReportServer].dbo.AddEvent @EventType='TimedSubscription', @EventData='b64ce7ec-d598-45cd-bbc2-ea202e0c129d'
Please note that the command ‘exec [ReportServer].dbo.AddEvent @EventType='TimedSubscription', @EventData='b64ce7ec-d598-45cd-bbc2-ea202e0c129d'’ is coming from the job properties. We can go to SQL Server Agent Jobs, right-click the corresponding job to open
the Steps, copy the step command, and then paste it to the query.
Then when the user table has data insert, update or delete, the trigger will be triggered and execute the subscription to send email to users.

How to create a hyperlink in RTF template to navigate within the report

Hi,
I have an RTF template for one of my report and in that i want to provide hyperlink "Top" which will take the user to the beginning of the report. The output of the report is in HTML format which gets displayed on the browser.
Since the report has some many tables and is very lengthy i wanted to provide an hyperlink which will navigate to the top at the end of each table.
I formatted my report title as "Heading1" and created an hyperlink at the bottom of the table in the template and pointed it to the above heading. But still i am not able to navigate to the top from the HTML report that gets generated.
I have the template and the sample xml file at the following shared location:
\\Rakumara-pc\TO_XMLPUB_GURU folder.
Please take a look and help point out what am i doing wrong.

Problem with implemnting delete for each record in the report

Hello all,
I am having trouble implementing the following requirement in my application.
In the reports, in each row..I need a delete button. Only few Users( Managers/Administrators) should be able to view this button. Rest should be able to see the normal report. Also when the user clicks on delete, the record should not be actually deleted but a column named Active/Inactive should be made InActive.( The report has only records which are active).
My problem is when the user clicks on edit button, I dont want to go to another page and perform delete operation. I should be able to modify the record in the same report page. Is this possible?
It would be really great if someone can give me inputs on how to do this..
Thanks,
shravanthi

See this link for possible solution:
Coding a delete process
You will need to modify to do your "Delete"
There is also Dene's Wonderful example application that shows a similar idea, but again you will need to modify to get your "delete" status set in the rows

XML Publisher report errors out when RDF report has no data

Hi everyone,
I created a template and attached it to an RDF. When i run the oracle report with the attached template, if the report has 'not data exists' the report is erroring out. is it the normal functionality of XML publiher??. Because i remember at my earlier client i have run some reports for which if 'no data exists' still the program would complete normal but the output would be blank.
The xml output is creating the tags for the elements.
any help appeciated.
Thanks
sam

Hi Sam,
Yes this will happen depending on what the template is repeating on etc. You can handle this quite easily using sub-templates.
Firstly create your normal template as a sub-template (so surrounded by the <?template:TEMPLATE_NAME?> tags)
Then create a second template that contains the text "NO DATA FOUND" as another sub-template.
Create a third template (this will be your main template called by the report), which imports the two sub-templates, then using a choose statement, count the number of occurences of you main repeating group in your XML. If the count = 0 then call the "NO_DATA_FOUND" sub-template, otherwise call the normal sub-template.
I hope this helps, if you need an example I can send you one, just let me know your email address.

Cj

The Report is Empty.

Hi,
Im using Crystal Reports 2008 on VS.NET 2005 and .NET 2.0
I set the dataset to the report programatically.
The report viewer is empty.
But the report has more than 2 pages.
When I click next page on the Crystal Report Toolbar, the report data appears. But not when it is loaded.
This has worked fine before. The code has not been changed but something did change and screwed up the report.
Please help me here.
Aswin Dwarakanath.

I'd recommend the following:
Export the report to Crystal Reports format. See if the fields (in the CR designer) are stripped out from the exported report. If they are , you have a dataset issue where you are not matching the schema the report is expecting. To check that, do the following:
1) Write out your dataset to XML:
myDataset.WriteXml(xmlPath, XmlWriteMode.WriteSchema)
so, in your case you want to write out the xml after
cr.Subreports.Item("Transaction Breakdown").SetDataSource(clientTotals) and
cr.Subreports.Item("Last10Weeks").SetDataSource(transactionTotals)
E.g.;
cr.Subreports.Item("Transaction Breakdown").SetDataSource(clientTotals)
clientTotals.WriteXml(xmlPath, XmlWriteMode.WriteSchema)
cr.Subreports.Item("Last10Weeks").SetDataSource(transactionTotals)
transactionTotals.WriteXml(xmlPath, XmlWriteMode.WriteSchema)
Now, I do not see where or how you are setting the datasource to the main report, so if you are also using dataset, do the same for it.
2) Open your report in the CR designer.
3) Go to the Database menu and select "Set datasource location"
4) Choose "Create new connection"
5) Choose ADO .NET (XML)
6) Point to your xml
7) Click on he <Update> button.
If you get a field mapping dialog, the schema of your dataset is different from what the report is expecting and you need to adjust that.

Error RCIRAS0546, failure occured while the report was being processed

Does someone know this problem and what to do about this?

We got this error message on a report that had 5 subreports, 3 of which were based on stored procedures. The report was running fine in our Dev environment and in the CR developer, but not when we published it to another environment. The problem was caused because the stored procedures had been changed in Dev (so that they ran correctly) but these changes had not been released to the other environment. Once the scripts were run to update the stored procedures the report ran successfully. So it apepars that the problem was because the stored procedure/s the subreports were using were failing, but we only got the RCIRAS0546 error message.

[Trouble] The Report has no tables
