Crystal Reports Linear Regression Trendline Slope

I need to know the slope of my linear regression trendline from my chart to determine whether the trend is positive or negative. I can't find any information on how to display and/or use that value in a formula.

It appears that the steps I was taking was incorrect. To actually get the trendline, you need to click the line in the line chart that you want the trendline to be against. Follow the steps above BUT do not start it from the legend.

Crystal Report Chart Problem: No trendlines with regression

Hi,
I have a severe problem with chart trendlines in Crystal Reports 2008 (12.3.0.601).
Trendlines with regression do not work, whereas average and moving average work on charts with data axis but not with numerical axis.
Does anyone has an idea, how to solve it.
Best regards
Michael

hi,
Try to create a bar chart with Year, Quarter as dimensions and Sales revenue as measure.
Now your chart has legend which shows quarter values.
Right Click the Legend value Q1 -> Series Options -> Trendline.
Choose the required regression type: Linear/ Polynomial/ Logarthmic/ exponential/ Moving Average.
This will show the required trend line.

Crystal Reports regression to 10.5 from 11.5

I'm a long time user that went with the full version of Crystal Report 11.5 to have use of the stand along viewer instead of merge modules with VS2005. Now, with VS2008/CR10.5 the viewer (for deployment) exists both for x86 and x64 platforms. This is great. And, appears to work good.
I'm not having the same experience with VS2008 and CR2008 (v12.0). The problem is deploying on a 64 bit machine. Nothing seems to work. I get an runtime error message stating that permissions are insufficient or that the viewer was not installed correctly.
So, given the fact that VS2008/CR2008-Basic now does what previous version should have done -- how do I migrate by 11.5 reports back to 10.5?
Thanks,
Eric

There are a couple of things in here to consider;
how do I migrate by 11.5 reports back to 10.5?
Not sure that you'd want to. If the 11.5 reports use a feature that is not in CR 10.5, you will at minimum get weird reports, at worst the reports will throw error messages.
Thus, I think the place to start is with troubleshooting the issue when you run CR 2008;
make sure you have at least SP 1 installed;
https://smpdl.sap-ag.de/~sapidp/012002523100006555792009E/cr2008win_sp1.exe
SP2 is here;
https://smpdl.sap-ag.de/~sapidp/012002523100009038092009E/cr2008win_sp2.exe
make sure you have the correct runtime installed. see [this|https://wiki.sdn.sap.com/wiki/pages/viewpage.action?pageId=56787567] wiki for download links.
check out [this|https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/10d5fa88-2013-2c10-c9a5-f11963607d4e] article re. running CR on 64 bit OS.
If none of the above helps, let me know the exact error message / behavior, etc. on that 64 bit OS. Also, search these forums for 64 bit - there is a number of threads that may also point you in the right direction.

Accessing trend line formula in Crystal Report

I am using Crystal Reports 8.5 and CR2008. I have a report showing a trend line (specifically the quadratic regression). I can show the formula that is being used for the report in the chart. How can I access the regression formula in Crystal Reports?
Thank you for your help.

hi James,
in short you can't...the charting engine is a separate 3rd party dll so what you see there is not necessarily available in the rest of cr in summaries etc.
in order to do things like this, you either have to do the calcs on your database or using formulas. i've attached an example of linear regression that i did a while ago. change the .txt extension to .rpt after you extract the contents. sorry, there are no instructions on how to do this.
on the attached sample though it does figure out the regression formula and also extrapolate data, show residuals etc. there are a couple of other "fits" in a parameter but i never finished those as it made my head hurt

Use of Grid in crystal report designer

Hello,
I have a simple question in regards to data grid in crystal report designer. Crystal report designer has a capability to show grid in both design and preview mode, can we make use of any other grid in crystal, how can I make my report look more professional like the text box alignment and placed objects based on using grids?

I am confused as to what you are asking. You can align text boxes and lines/linear boxes using the grid in the report design tool just like other report objects. You can achieve some very crisp looking report designs this way. There are also tools available when you right-click one or more objects to size and/or align those objects within the page.

Who notes you can also change the spacing between guidelines and grid points to provide more control over layout...

Crystal Reports version 13 managed api's run slower than native version 11

Hello,
I am a senior engineer, working in a project of porting client code written in C++ using Crystal 11. It uses the native COM api like shown approximately in the following code fragment:-
IApplicationPtr pApplication;
pApplication.CreateInstance("CrystalRuntime.Application.11");
pReport = pApplication->OpenReport("myreportfile.rpt", vtOpenMethod);
... code to setup Export Options, setLogonInfo on database, set parameters for report etc.
pReport->Export(false);
This code is launched in few threads, and works nicely, and a very stable used code in real world.
We have ported this to Crystal 13 .NET api's and our code approximately looks like
ReportDocument document = new ReportDocument();
document.Load("myreportfile.rpt", OpenReportByTempCopy);
.. set diskfile format options, pdf format options, paramters, logon info etc. very very similar to the native C++ code, almost matching 1 by 1 line
document.Export();
document.Close();
No problem so far, and it works fine. This is also launched in multiple threads same in number like native, and works fine. We get the same pdf file generated.
But here is the problem. In native we are getting easily around 2000 reports in 20 mins. But in managed we are taking 35 mins for the same set of reports. The output looks fine and same etc. But there is a good 40-50% performance regression, and we have tried so many things, but never able to beat this 40-50% perf degradation.
Can you please help ? A few questions. First are we executing document.Export really concurrently ? Is there any waiting or serialization going on insider Crystal api's. Is this Crystal 13 managed api, a thin stub layer just passing on to native COM apartment threaded dll. Can this layer introduce such a delay ?
A few things we have tried and haven't succeeded for summary:-
1. Opened 1 dummy report in the beginning and kept opened throught, to flush any ref counted inits
2. Didn't perform Close immediately, but had another thread chew on it and Close delayed
3. Reduced the thread to 1, (in native as well), again our perf degradation is comparable.
4. Optimized the reports from various suggestion in this forum. Did better, but so did the native, and still we are comparatively poorer.
Thanks for the same, Eager to supply more info if required.

First I'd like you to have a look at the document SAP Crystal Reports Engine in a Multi-Threaded Visual Studio Application. Next make sure you are using SP 10 for CRVS.
Next, you will have to tell me what database you are using, connection type and if MS SQL, what client?
BTW.; these being community forums, you may get an answer, you may not. It may be timely, or not. If you are looking for a faster response, there is the option of creating a phone incident here:

Failed to schedule crystal report

Hi,
We are using BO XI R3.1 and I am trying to schedule a crystal report in CMC in pdf format which contains parameters. After the schedule the error message am getting was Error in File ~tmp29bc61e513637d0.rpt: Failed to retrieve data from the database. Details: [Database Vendor Code: 2812 ]
I've also checked if there is an issue with servers and all of them are running.
However when i try to view the report manually by giving the parameters it ran fine and i was able to see the report.
Could any one please advise me what could be the issue i really appreciate your help on this regard.
Thanks,
Eswar

Well exporting a report from the viewer to pdf and scheduling to pdf both use the same conversion driver. I can't say I've ever seen a difference in formatting when scheduling vs exporting from InfoView after a view. Is it possible you are comparing the results from the CR designer and exporting to pdf vs scheduling to pdf?
Do this:
1.) open the report in the CR Designer on the server machine. Refresh it and export to pdf and save the file.
2.) open the same report you published to the CMS and view from InfoView. Refresh it and make sure to use the same exact parameter values you did in #1. Export to pdf and save the document with a different name.
3.) schedule the same report to pdf & unmanaged disk destination using the same parameter values in #1.
Compare all 3 files. Are they still different? They should all be identical reports assuming the data on the db side didn't change between refreshes. Using the same parameter values is important because this can change the data as well as the formatting you've designed the report with. If you're still getting blank pages or the output files are different in any way, you'll probably want to open a support ticket. Someone in support can help you compare files, formatting and the make sure the version you are using doesn't have a regression.

How to create a linear regression line series

I am relatively new to Flex and I am currently working with charts in the data visualization components. It has been requested that I add a linear trendline (ie, linear regression trend line) to a column chart. From what I can tell, there is no linear regression form for the mx:LineSeries. Has anyone created a linear trendline using the data visualization components in Flex, or does anyone have any suggestions on how to accomplish this?

Nicholas @ Bime posted a solution to this sort of problem earlier this year, apparently. He created a custom component that extends the CartesianDataCanvas, and can be called as an annotation element of the chart. See the following url: http://bimehq.com/data-visualization/introducing-flex-charting-trend-line-component/
His solution works very well, with the only caveat being if you have mutiple series on your chart, all the trendlines will be the same color, and there is no label on the lines to show which line corresponds to which series.

Sales quote layout rows doubled in crystal report layout

Dear All,
Sales quote layout rows doubled in crystal report layout.
In sales quote layout the rows are doubled. Even in the standard layout. If the quote contains only two rows. Then it is doubled as 4 rows in the crystal report layout.
It is happening in the particular database. Other database are working fine. I request you people to help me to overcome this issue.

Siva

Hi Siva,

Hi Nagarajan,
thanks for reply..
1) Yes, i.e i have taken into BomType: Template
2) i did not get any helpful output by using treetype by keeping 'S' and 'N', i kept in comment.
3) Actually MT0001-05 - these are material item- unit prices are fixed. see in attached image
     for parent item, unit prices are not fixed. I give the price for them in Sale Order.
     I want unit price for parent and child should be summed/cumulative for Sale Order print.
     (in my above post, first matrix exactly same as sale order line items plz check it)
Please help me, how i can achieve this by query(for PLd or Crystal report)
With Regards

SQL Connections remain open after Crystal Report closes

I am wirting an interface to use the crystal report viewer to print reports, connecting to a Progress Open Edge 10.1B database. From our application we declare the application, report, exportoptions and connectionproperties objects and pass these to the crystal reports viewer. Once the report is printed we release the objects and set their variables for null. However we are finding that the SQL connection to the database is remaining connected and we can only release the connection by manually going in a disconnecting.
I have read in forums that people use .dispose or .close to release the connection, however we do not have access to these methods as we do not use .NET. Are there any methods we can use to disconnect these sql connections?

Hi Dean,
Moved to the Legacy Application forums. Likely using the RDC as your report engine.
You should still be able to close and dispose of the report objects. They are not specific to .NET.
In VB it would look something like these lines::
    crReport.Close
    Set CrystalActiveXReportViewer1.ReportSource = Nothing
    Set crReport = Nothing
Once the report is closed it should disconnect from the DB. If you close the application does that disconnect?
Have you looked on 4GL's site for info on how to?
Thank you
Don

Dunning Letter as Crystal Report: What tables? (SAP B1 9.0)

Dear Experts,
I am being asked to revise the Dunning Letters for our clients. The existing PLDs for each Dunning Letter shows most data fields as system variables. The existing Crystal Report for Dunning Letter 1 is a conversion from the PLD and doesn't show table information for most of the report's main items. There are tables in the report but they are standard ones (OADM, OADP, OCRD, OHEM, OSLP). It also includes a "table" called "PLD__ITEMS" which has all the PLD system variables and no B1 table or field/column information.
As I'm just now starting to work with dunning letters, I see that I can't even run this report in Crystal. The PLD__Items datasource prompts me for a file path and class name. Any ideas what one enters here to run the report outside of B1 (from the Crystal report designer)?
The main focus of my question is: Has anyone created a Crystal Report to replicate the Dunning Letter and if so, what tables are involved and how are they connected? If I can create a Dunning Letter entirely in Crystal, I can replicate it across all clients and get the correct fields/columns of data the clients want. The inclusion of the PLD__Items apparently limits my ability to test the results. I would prefer to avoid the PLD limitations.
Thanks for any assistance.

Thank you Nagarajan. I have a dunning letter created in Crystal Reports for our client. It is fairly limited in scope, it just has the customer name and address, invoice numbers and dates, amounts due and the text they wanted in it.
I can import it into B1 9.0 and set it as the default for Dunning Letter #1 and it runs, but unlike other formats where there is a DocEntry and/or ObjectID and a ?DocKey@ or ?ObjectId@ parameter, how do I limit the report to just one customer? Typical document layouts run for the document that's on the screen. In the dunning process, the report runs once for every customer when the Dunning Letter Method is set to "One Letter per BP". I have to limit the report to one customer at a time. Right now, each dunning letter based on the Crystal report is identical and it contains all the data for every customer.
So, does anyone have any ideas for what selection criteria needs to be included in the Crystal report to have it select just one customer from the dunning wizard tables? Thanks.
Michael
Edit: I created a ?WizardID@ parameter and a ?CardCode@ parameter to limit the report to a single dunning wizard event and a single customer. While it works fine in Crystal itself, it doesn't work in B1 at all. I had thought that by limiting the report in this way, it would only create dunning letters for a single customer.

Exporting Crystal Report to HTML is not working in Windows 7

Code working fine at Windows XP, But it is not woking in Windows 7 environment.
Please can anyone share your valuable thoughts or ideas reg. this.
Thanks in Advance

It looks like inheritance is broken in the component hierarchy for JFrame in Windows 7 JDK 1.6.0_23-b05. The only thing remotely related to inheritance in your code snippet is the WindowListener, which does little. See camickr's advice about built-in exit management.
EDIT - using the post title as a clue, I realize you may be talking about the component hierarchy, and whether the contentPane's background is visible through the upper layers. Instead of guessing, I'd prefer you describe your "issue" accurately (observed vs expected behavior).

Print crystal report without using the print button on toolbar

Hi,
I am working on Crystal report XI. I need to print the report w/o using the toolbar. So I have inserted a print icon in the report. On clicking that icon it should call a jsp page which will print the report. I am not able to call any print methods provided by JRC to do this.
Can someone help me with this problem.
Is there some other way to implement it ?
Thanks

Print the report where? On what printer? The server's printer?
Java code runs on the server. You can't affect the client's computer from JSP.
You can write javascript code which can call window.print() but that is working through the browser to display the print dialog box (as if the user selected file:print)
