Linking Parameters to sub report from main report.

When we link a formula in a main report to a sub report parameter and then use the sub report parameter in a SQL Command to an Oracle database, the Crystal Report works in Crystal Reports 2008 but not in CRFE 2.0 SP1. Please help how to do this. I'm restoring the sub report links after changing the database connection info as per Ted's advice in another thread. Please note that I can see and print the parameters being passed in the sub report. It's only that I can not use it in the SQL command.
We get the following exception

Hi Thomas,
Thanks for the idea but the problem is not that simple, as I'm developing a framework for Crystal Reports 2008 for use at work for future projects. It is not developer-friendly for developers who will use the framework to have a pre-processing just to predict the values they will use for the sub-reports and feed it via the main report (we will not be even sure of the number of parameters to allot for the subreport if that was the case) when all they really needed was a single value.
e.g. Reports on Departments in a Location (parameter) and the Officers in each Location
Main Report will query for the Departments in a certain location and other information about it
Sub report will query for the Officers in the department and their Information (linked to main report via department ID)
All the developer needed to provide was the Location parameter. I can't make it hard for them so that they need to revise their templates because the new JRC can't process this template. The said template worked in JRC in Crystal Reports XI, that's why I'm thinking there should be a way (I might just have made a mistake or two in what I'm doing in the new JRC). Or is there a bug in the new JRC? I'm hoping for our SAP forum guys here (Ted or other people from SAP) to clear this up.
Thanks a lot.
Regards,
Rizza
P.S. For snippets of my code, please see JRC for Crystal Reports for Eclipse V2.0 Parameter Problems

Passing values from main report to sub-reports

- How do we pass values from main report to sub-report?

Look at this link which shows how to pass values from a subreport to a main report.
http://www.datamanagementgroup.com/resources/trainerstalk/trainerstalk_howto_share_subreport_data_with_main_report.asp
You can use the same method to pass values from main report to a subreport.
1) Create a formula @mainFormula in the main report, as given in item 1 of link.
2) Place this formulla in a suppressed report footer section above the target subreport.
3) In the subreport, create a formula @subFormula that declares the same variable name, as given in item 3 of link.
4) Place @subFormula column in the subreport where you want to display it.

How to pass the value from Sub report to main report

I have un report(mainreport) within a subreport(subreport).
With reporting services, how to pass the value from Sub report to main report?
thanks

Hi Alebet,
With reporting services to pass values from sub report in to main report is not supported directly.
But there are some workarounds through which you can get this .
There are two ways to get this.
1- Put your sub report query into some table. i mean to say through the subreport query get some temporary table.
2- Using this temporary tables data write some Scala function in the data base.
3- Now in your main report query return this scala function as a column.
4- Extract the column value where ever you want in your main report which is getting calculated from the subreport query. so you will be getting the values returned from the subreport in the main report.
This will definitely work fine as i have done some report in this way.
Another way of doing is that
1- prepare another data set with the same query as in sub report in the data tab.
2- then refer this 2nd dataset in your main report .
But better way will be the top one.
Anyway please let me know if you get the solution.
Thanks
Mahasweta

How to know how many rows including headers and footers does subreport has from Main Report

Hi, we are sturuggling with subreports. Main report has 3 subreports, each subreport is inplmented in a group header(3 subreports and 3 group headers). We would like to print a group header under subreport as a column header every page, and need a page break when group number is changed. This report exports a MS Excel(97-2003) report file.
In main report, [New After Page] is checked under Group Header #1d from [Section Expert]
In each subreport, [Repeat Group Header On Each Page] is checked under the highest group from [Group Expert]
Here are two issues;
Since Crystal Reports has more rows than Excel in one page, colmun header in each subreport is being printed in the middle of the page. It should be printed at the top of the page
When Subreport has many rows and has to be printed in more than 1 page, a page break is automatically inserted before column header. It should be printed right below column header which is Group Header #1
We have been trying to pass row counts(count of group header because group header is used as the details) using a shared variable from Subreport 1 to Subreport 2 via main report since Subreport2 cannot predict how many rows Subreport 1 has.
Here is what we are trying but we are getting an error which is "A constant expression is required here" under main report
- In Sunreport 1
whileprintingrecords;
shared numbervar SubGroupCount := DistinctCount({Table.Field});
- In Mainreport
shared numbervar SubGroupCount;
if(pagenumber) = 1
then (SubGroupCount)
else 50
Is there any solutionss or better ways other than above?
Thank you,
Main Report: Group Header #1a --> as Page Header
Run Date: mm/dd/yyyy Report Name
Main Report Group Header #1b --> Subreport 1
Header 1
Header 2
Header 3
Header 4
Header 5
Header 6
Main Report Goup Header #1c --> Subreport 2
Header 1
Header 2
Header 3
Header 4
Header 5
Header 6
Main Report Froup Header #1d --> Subreport 3
Header 1
Header 2
Header 3
Header 4
Header 5
Header 6

Thank you for your reply and sorry for my complicated explanations. The report has confidential information, so I replaced to some fake data but I believe you can still see what I am trying to do..
Main Report
Subreport 2
Output1
Output2: the following page
--> more rows are printed..
We have two problems;
1. The column header in Output2 is supposed to be pronted right below the last row in Output2, however, a page break is automatically inserted. But even in the same output document, it works for some group when it has a few rows..
2. Since Crystal Reports prints more rows in one page than MS Excel does, Column header is not be printed at the top of the page.
I tried the way you advised me but it did not work..

Filter condition not working when Navigating from Main report to detail

Hello,
I have one report in OBIEE 10.3.4. Below is the filter condition used in Main report:-
(Customer Secondary Organization is equal to / is in BMS OTHER C
AND Customer Tertiary Organization is equal to / is in S&FO )
OR Customer Secondary Organization is equal to / is in MKTG
Also in my detail report I am using the same filter conditions:-
(Customer Secondary Organization is equal to / is in BMS OTHER C
AND Customer Tertiary Organization is equal to / is in S&FO)
OR Customer Secondary Organization is equal to / is in MKTG
Now when I am navigating from Main report to Detail report, then this filter condition is getting overridden by below condition:-
Customer Secondary Organization is equal to MKTG
and Customer Tertiary Organization is equal to S&FO
or Customer Secondary Organization is equal to MKTG
What I noticed is If I rearrange the filters and make it as below:-
(Customer Secondary Organization is equal to / is in MKTG
AND Customer Tertiary Organization is equal to / is in S&FO)
OR Customer Secondary Organization is equal to / is in BMS OTHER C
Then I am getting the filter in detail report as:-
Customer Secondary Organization is equal to BMS OTHER C
and Customer Tertiary Organization is equal to S&FO
or Customer Secondary Organization is equal to BMS OTHER C
It is taking Secondary Organization which is 2nd one in the main report.
Can anyone please help me on this.
Thank You,
Shivam Saxena

Hi,
What you can try is refer the filte condition in the main report to the detailed report with the option--> Filter based on another request.
Or you try creating another intermediate report which will refer the main report filters and pass the filters to the detailed report.
Hope this helps.

CR2008 Not enough memory while exporting reports from Crystal Reports 2008

Can someone help me resolve the issue.

The .rpt file size is 14MB with the Data Save option enabled, 12MB without Data Save. Presumably the 12MB file size is because of the 24bit PNG we have as our background.
The Designer executes the report in less than a second and we can scroll through all pages and see the image fields perfectly.
When we Export to PDF, the Designer takes a long time, eventually gets to the 77%, the 7th record and returns "Export report failed" followed by "Memory full". If we export only page 1 of the 3 pages, it also returns a Memory full error. However, when the same report is run with only 1 page, that page exports to PDF but with a ridiculously large size and export time.
The machine has 2GB of physical memory with an 8GB pagefile with Windows 2003 (latest everything). The process runs up to about 1GB before reporting the memory full error.
We've also tried a variety of other suggestions posted in the other thread with no success.
We're happy to provide the RPT file to the Report Team to diagnose the problem. Ultimately, we need to be able to produce a 15 page report with approximately 45 images.
Our preferred scenario is fixing problem 2. The CR Designer seems quite capable of rendering our report and printing it to our third party PDF printer in a timely manner with small size. However, the API reports memory full.
The API resides in a dedicated reporting web service with NO other code except for loading the report, setting parameters and printing. When executing, it uses up to about 1.1GB before reporting the error.
Are there any other suggestions for fixing what we have? Are there known problems with large images in reports? Do we need to lodge a formal support request?

Calling a report from a report (10g)

Hi
I am using DeveloperSuite 10g and Application Server 9.0.4 - I am trying to call a report from another report.
I believe I am correct in thinking that as buttons don't exist in reports any more I have to use a hyperlink containing the URL to the reports service with appropriate parameters to invoke the required report.
My problem is that when I click on the hyperlink I do not see the called report, but get an html screen saying "Oracle Report Status - Successfully run".
My hyperlink is formed like this:
/reports/rwservlet?module=reportb.rdf
Is there an additional parameter I must pass to get the report to display on the client browser window?
Thanks

Hi,
Can someone let me know as to what the maximum length of the URL string that could be formed? I believe in IE browser a maximum of 64,000 characters can only be formed. If I need to pass many parameters and the length of the values passed exceeds the default length in IE, the rest of the values will not be captured in the report server.
Please let me know on how to proceed with this problem.
