Crystal reports 10 and Enterprise sql nolock

Post Author: Dis1931
CA Forum: Data Connectivity and SQL
Occasionally we have an issue where it seems the Crystal Reports Enterprise server causes a lock on one of our databases. Doesn't happen all the time and we have not been able to narrow it down. This prevents all users from connecting to the database and working...this is obviously not good. When we find out we kill the PID in sql that is causing the lock. Then all is fine.
My question is whether there is a way to perform a query using nolock in Crystal Reports 10 or of configuring it on the Enterprise server? Is this called something else in Crystal?
I realize that this could lead to reading uncommitted data or that data may change while I am reading it, etc...but I would rather have a bad report every once in a while than to have it lock up the database every once in a while. If there are other problems resulting from using nolock or a similar command let me know. Is this possible?
I looked into connection strings as well and couldn't find a way to specify locking or in this case no locking.
I would change the SQL query in Crystal Reports but this functionality seems to have been removed since version 8.5. If there is a way to edit the query directly that would be acceptable as well.
Any help would be greatly appreciated. Thanks in advance.

Did you ever find a solution to this? I just upgraded from Crystal 8 to 10 and of course didn't discover this issue during my testing, never thought of it, but then locks (in sql it shows as blocking) started showing up during production locking people out of the database and bringing production to a hault. I have searced for two days and cannot find a way to stop this, I was hoping there was a setting in Crystal to preventing blocking, or maybe something I could add to the select statement, someone said I could add 'noblock' but I can't find any info on this.

Crystal Reports 9 and SQL Server 2005 default parameter values

We're using Crystal Reports 9 and upgraded from SQL Server 2000 to SQL Server 2005.
I'm noticing a very weird problem which I wonder if anyone else has experienced (and hopefully found a resolution for). It appears that in using Crystal with SQL Server 2005 stored procedures, if we have default parameter values in the stored procedures, the default parameter values get completely ignored if you pass in a NULL value from Crystal!
For example, if you have a stored procedure that begins like this:
ALTER Procedure [dbo].[StoredProcedure]
@Param1 VarChar(200) = '',
@Param2 VarChar(200) = ''
AS ...
both @Param1 and @Param2 have a default value of an empty string, and therefore should become empty strings if nothing (NULL values) gets passed in for them.
But, like I said, what I'm finding is that with Crystal calling the stored procedure with NULL @Param1 and @Param2 values, they never become empty strings, but rather remain as NULLs.
This was never a problem with SQL 2000.
Very perplexing. Anyone else every experience this?
Thank you.

Please ignore my earlier post -- answered my own question.
NULL parameter values do not get replaced by default values in SQL -- that is normal behavior in both SQL 2000 and SQL 2005. Just goes to show, that no many how many years programming experience you have, you can still get tripped up sometimes : (

Crystal Report viewing and Printing Issue

Hi Experts
I use crystal Reports for PO,AR Invoice,Delivery and many other documents.It takes more than 5 mins to view layout from crystal report and print sequence printing takes more than 10mins.Please Help me to rectify this issue..
Regards
Naresh Kumar

Hi Naresh,
What is your SAP version and Patch Level ?
I believe in new version this issue has been addressed by SAP. Also note SAP B1 8.81 PL 07 has some issues in crystal Report, it asks for SQL user id and password, SAP is aware of this issue. So if you plan upgrade to latest PL then ensure that Crystal report issue is resolved, otherwise you will be in trouble.

Crystal Reports hanging in Enterprise

Just suddenly we are facing issues with some of the crystal reports . they were working fine in Business objects up to yesterday but today they are hanging , even when we try to open/modify parameter they hang. we are using Crystal report 2008 and BO R3.1.
evnthough some reports hangs the others just run fine.
we noticed that , the reports which are stopped working are the ones that have " Printer Option" unchecked in Crystal Report designer . when we open these reports in designer and check that option on pagesetup and save them back in enterprise they are working.
I have no luck to find the rootcause of this issue. what have changed that caused this issue.
It is happening on both test and production environments. I read somewhere on forum that it might be related to printer driver, but we haven't updated any driver and nothing seems to be changed.
any ideas?

In the page setup put the option Microsoft XPS Document Writer in the Printer option before publishing it to BO Server .

Crystal Reports 2011 and connection to Universe or repository

Hello,
i have CRW2011 Beta and Interactive Analysis and want to connect to a created universe (which i created with the univrese designer from Interactive analysis).
I don't have any SAP Business Objects server etc...
How can i connect to my created univers. If i try to do, CRW2011 he asks me for a server.
As i remember a SAP technologist do a statement, that this is possible in CRW2011 but was not possible in earlier versions.
Or what is the minimum installation base a need on a local machine?
I need this solution, that i must not declare Business logic for every report again. And this solution should be for
small-size customers.
Customer side environments
- Crystal Reports Server 2008 (if available 2011)
- Crystal Reports Designer / Viewer
- Pervasive SQL DBMS

Hi Andreas,
Universes can only be connected to by logging onto a BOE Server. It's always been this way and I don't recall anyone saying that has changed. BOE 4.0 is using a new Universe file name and format so any older Universes will be upgraded.
As for off line Universe support that won't be supported in the current release and I don't recall anyone telling me it will ever be.
Who told you you could?
Thank you

Crystal Reports export and print fails with SSL / https but works with http

Windows 2008 Server, 32-bit (IIS7)
ASP.NET 2.0
Ajax 1.0
Crystal Reports version 10.5.3700.0
http: printing works, export works
https: printing not working, only export to MS Excel and MS Word work.
I am able to generate reports using both http and https, and the toolbar icons are all showing. However, I am unable to print or export properly with SSL.
Printing prompts me with a select printer window, and then a window 'Retrieving Page 1' follow by two messages from Crystal Print Control both stating:
A communication error occured. Printing will be stopped.
Exporting generates various errors depending on which export method is being selected (however Excel and Word work over https).
I've found the same problem on this site and other forums, but never a resolution to get exporting and printing to work with SSL. Will someone please provide me assistance or possibly relay what settings they're using if they have Crystal Reports export or printing working over SSL in IIS7? Everything works fine when I change the address from https to http.
Please let me know if I can help by providing further information. We've gone through a great deal of possible solutions with code and I'm currently looking in to IIS settings again.
Thank you.

Thanks Ludek. I got it by searching KB number.
Unfortunately, it didn’t fix my problem even my IE (IE8 and IE 9) has correct setting. I double check my version. PrintControl.CAB is version 10.2.0.1146. we use VS 2005 Crystal report and VB .NET. It works fine on HTTP. But when we use HTTPS (SSL Certificate from go daddy).
1: Crystal report export
            Export to MS Excel, Word: pop us “File download”, then click “Save”. It says “Internet Explorer cannot download ReportView.aspx from my site. Internet Explorer was not able to open this internet site. the requested site is either unavailable or cannot be found. Please try it again later”
            Export to RPt, Rich text format: It says “Internet Explorer cannot download ReportView.aspx from my site. Internet Explorer was not able to open this internet site. the requested site is either unavailable or cannot be found. Please try it again later”
            Export to PDF : nothing happened.
2: Print:
            Pop up dialog to select printer, click “Print” “. Shows windows “Crystal Report Viewer” and pop us error message box. Title is “Crystal Print Control”. Message is “An communication error occurred. Printing will be stopped”. Click “OK” and pop up error message box again.
Please advise.
Thank you very much!

Crystal Reports 9 and Dot Net 2 SP2

We have a VB6 application that uses Crystal Reports 9 and makes a call to DB2. When we patched the Windows 2003 server it runs on to Dot Net 2 SP2, the call to DB2 would hang. If we removed the patch, the problem goes away. Microsoft said this is a Crystal issue not a dot net issue so they referred me to this site. Has anyone seen anything like this or have any suggestions as to how to get around this? Our Infrastructure Admins would like to get Dot Net 2 SP2 on ths server so I can't leave it unpatched indefintiely. Thanks

Hi Brian,
Moved your post to the Legacy SDK forum.
Which report engine are you using in your app?
Cr 9 is end of support long time ago so nothing we can do to fix this other than to upgrade to CR for .NET components. Or possibly CR XI R2 and the RDC if that is what you are using.
What error do you get?

Crystal Reports 2008 and Postscript

Hello,
I think I have to start a new thread for this. Originally I described the problem here:
Printing Crystal Report to Postscript
Now we upgraded our Crystal Reports for Visual Studio 2005 to the latest version - CR 2008 SP0. We had purchased the full version to be able to print the postscript files correctly, without any prompts for the file name, because I've read that this was a bug in the old versions, but it had been fixed. But I still cannot do this.
I'm trying to print my reports to the postscript file:
PrinterSettings ps = new PrinterSettings();
ps.PrinterName = "TRADEPOSTSCRIPT";
ps.PrintFileName = txtPath.Text.Trim() + "
" + txtFormNo.Text.Trim() +
".ps";
ps.PrintToFile = true;
rpt.PrintOptions.CopyFrom(ps, ps.DefaultPageSettings);
rpt.PrintToPrinter(1, true, 0, 0);
I'm still getting prompt for the file name.
This doesn't make any sense - the path and file name are specified in my code. The whole project will be useless for us if the users will be getting prompts.
Could you please help me how to solve this issue?
Thank you,
Peter Afonin

Hi,
I am trying to print and specify a filename to a postscript printer as well. However, my version of crystal reports in Visual Studio 2008 does not come with this method....
reportDocument.PrintToPrinter(printerSettings, pageSettings, True) ?
I have checked and there does not exist an overloaded method in the object browser for this 'PrintToPrinter' method that would accept PrinterSettings object??
The only method I have is as below:
===============================
public virtual void PrintToPrinter(int nCopies, bool collated, int startPageN, int endPageN)
Member of CrystalDecisions.CrystalReports.Engine.ReportDocument
Summary:
Prints the specified pages of the report to the printer selected using the PrintOptions.PrinterName property. If no printer is selected, the default printer specified in the report will be used.
Parameters:
nCopies: Indicates the number of copies to print.
collated: Indicates whether to collate the pages.
startPageN: Indicates the first page to print.
endPageN: Indicates the last page to print.
===============================
My version is Crystal Reports Basic and is what comes with VS 2008 (not upgraded):
From the GAC:
CrystalDecisions.CrystalReports.Engine, Version=10.5.3700.0
FileVersion: 10.5.0.1943
.NET FRAMEWORK v3.5 SP1
Please help.
Thanks,

Crystal Reports 11 and 8.5

I have a 8.5 Crystal Report Server and need to update reports. We can't find our 8.5 license and needed to know if I can run a Cyrstal report written in version 11 and run on a 8.5 server.

Hi Tom,
No, Crystal Reports 8.5 file format can be read by CR 9 and above but CR 9 and above reports cannot be read by CR 8.5 and below. We updated CR 9 to fully support UNICODE and therefore the file format in CR 9 and above is not backward compatible or readable by CR 8.5.
Only option is to try to find an old copy of CR 8.5 and valid license.
Thank you

Crystal Reports 11 and 8.5 Compatibility

Post Author: mcneillb
CA Forum: Deployment
Can an application running Crystal Reports 11 and a legacy application running Crystal Reports 8.5 co-exist on the same system? The legacy application is a vb6 app and just uses the crystal report viewer. If they canu2019t what needs to be fixed or otherwise changed?
It appears if the legacy app is installed last, then the Crystal Reports 11 application is broken (its report viewer doesnu2019t work).
ThanksBlake

Hello Javier,
There isn't going to be much, if any, DLL files that are compatable with both. When version 9 was made it was redesigned from the ground up to be Unicode compliant. When this was done all DLL files that worked with the old versions would not work with the new versions.

Crystal Reports - Saving and the transport request screen

Good morning BI people,
Has anyone had this annoyance?
You are creating a Crystal report(2008 v12.2.7.598) with connection to sap bi(7.01) and when you save, the transport request screen doesn't come up front of crystal reports, it is created behide the screen. so, you sit and look at the hour glass for 5 mins, move on to other things, and then you realize that the transport screen is behide the crystal reports screen. and, it is not like you can minimize the crystal screen. you have to minimize all your screens and then click on the crystal screen from you tool bar and then, the transport screen comes up.
anyone have a fix for this?
or am i alone....
thx,
Erik

Hi Brad
I'm not sure that Modules would show us anything in this case, so let's try a few other things:
1) Make sure you are using SP 1 for Crystal Reports Basic Runtime for Visual Studio:
Crystal Reports for VS 2005 and VS 2008 Updates & Runtime Downloads
2) Seeing as this works on dev, this may be some db inconsistency so enabling the report option "Verify on 1st Print" will be a good idea.
3) Double check the database client and make sure the same client is used on dev and deployed systems. Actually I take back my Modules negative as this is where it may prove useful. Once you have the Modules logs, look at who is loading the crpe32.dll, then look at that process and see the client dlls.
4) Check the printer driver; see if there are any updates. Try a different printer driver.
Ten subreports is not too bad, though not that good either as you are loading the report engine with at minimum 11 simultaneous reports (each subreport is considered to be a report). If a subreport is in a details section and the details section returns a 100 records, you are running 100 + 1 reports. This may lead to memory issues, which may lead to the error.
If I was a betting man, I'd put most of my money on the printer driver (based on your last addition to your post). What ever money I had left would go to some database issue (be it actual data or client related).
