Data - Getting The Error "This Field Name Is Not Known" While Opening Crystal Reports

Feb 3, 2011

Working on a Migarition(VB6 to VB.Net(VS 2005)) application, where some of the reports are loaded in the application. The VB application is using the Crystal reports version 8. While migrating the application, we used the Crystal decisions and tried to load the report. Few of the reports are working fine, few are giving error(like boolean is required here, This field name is not known etc..). For few of the issues we have regenerated the report in CR XI it worked fine and few are giving the performance issue, but few reports are giving the same error as "This field name is not known".

To load the report we followed the steps.
1. Based on the user access level, the report connects to different DSNs.
2. Applies the LogonInfo to the report.
3. Sets the datatable as the datasource to the report
4. View the report.

If we run the application to load the report, it's throwing error as "This field Name is not known. Error in file C:Docs~UserLocal~TempSampleReport{EE6CC25A-D216-496C-AA95-E2F0C61718C6}.rpt:Error in Formula '{ViewReport.field} ="AB'"This field Name is not known".For this I have tried changing the setdatabaselocation in database expert.Still getting the error.The reports giving the error are using a View in it's Query. Is it causing the issue?

Group The Formula Field Results In Crystal Reports

Feb 1, 2012

I want Number of cartons and Pieces currently available in the stock that are about to expire in next 30 days and this is calculated based on expiry date...I have used formula field on crystal report to calculate current stock like "stock.crtns_added - stock.crtns_removed" and "stock.pieces_added - stock.pieces_removed"....Now I want to group by item name, category and expirydate because based on these three columns there can be more than 1 entries in the database....I want that when there are more than one entries the formula should sum up all the cartons and pieces for same item of a category with same expiry date and on report it should display just 1 line showing available cartons and pieces that are about to expire

How can i do this?? How can I apply group clause on the formula field in crystal report to get sum of cartons or pieces for each item based on expiry date??

Make Date Field Show In A Particular Format In Crystal Reports?

Jul 26, 2011

I am a bit new to crystal reports even though I've been doing a bit of heavy lifting with it.I have this crystal report that has a datetime field.This field has a default datetime of 1753-01-01 00:00. Now I want this field to display only date like "01-03-2011" and also anywhere it sees the default date, it should display an empty string like To achieve this I used this formular (in the display string)

if CurrentFieldValue = DateValue('1753-01-01 00:00:00') then
''
else
totext(CurrentFieldValue)

This successfully changes the default date to empty string. But now I can no longer change the format to dates only.

Asp.net - Crystal Reports Viewer: Failed To Open The Connection Error

Jun 19, 2012

Currently I'm working on a piece of code that involves using the Crystal Reports Viewer to export .RPT files to PDF. My problem is that the code works on literally everything except the website I'm planning to eventually put it on.

When placed on the website it throws back the error "Failed to open the connection." which I believe is connected to the SQL Server connection that's formed in order to read data for the report itself.

The code itself is solid and works when used in a separate console application I built to test it whether said code is run on my local machine or on the server itself. It even runs when I test the website in Visual Studio's virtual host.

I've narrowed it down to being some sort of permissions issue, but I am not knowledgeable enough in the various permissions settings to figure out which ones specifically apply to this situation. It's worth mentioning that other pages on the website are directly connecting to the same database, but they are doing so directly through Linq instead of going through the Crystal Report Viewer.

So does anybody know which settings I need to modify in order to fix the connection error.An added note: One of the other suggestions is to make sure there's an ODBC DNS in place that matches the one being used by the code. I have created such a DNS already.

C# - Crystal Reports 2011 .Net 4.0 OS Installed On E: Gives Error When Running Report

May 4, 2012

I have one PC whereby the OS has been installed on E: and it has no C: drive. Onto this I have installed my .Net 4.0 WPF Application which runs fine.

However, when I try to access a crystal report it gives the exception below. This user is able to access the report from its network location in windows explorer so I assume the act of asking Crystal to copy it locally is causing a problem?

Therefore, can anyone advise where the local copy will be created and/or how I can control this.

I am refactoring an old program to use VS2008 (instead of VS2005) and the 2003 Crystal Reports merge modules no longer work on the client machine. I am using the CR version bundled with VS2008. Neither the CR10 merge modules downloaded from the SAP site work, nor the CR x86 msi.

Settings In Crystal Reports That Modify Sort Order Of Data Sources?

Dec 3, 2009

I'm working with Crystal Reports in VB.NET in Visual Studio 2005.I have a List(Of Stuff) that I've sorted according to one of the object's members.I've verified in the debugger that the list is sorted correctly.When I define my list as the data source, as in

rptDetails.Subreports.Item("rptSubReport").SetDataSource(theListOfStuff)

and view the report, the list is reversed.So, looking for a workaround, I said, "OK, I'll sort the list backwards before binding it."The list still appeared backwards in the report.So something's happening, and I think it's within the report definition, because I don't know where else the sort order could be changed

Intermittent Crystal Reports Error "The Request Could Not Be Submitted For Background Processing."?

Feb 2, 2010

We are running Crystal Reports on a Windows Server 2008 with .NET framework 3.5 SP1. I have seen many causes of the general error "The request could not be submitted for background processing." on other forums, however they tend to be persistent and repeatable affecting just a single report due to a specific formatting issue with a specific report.We are seeing this error with the below stack trace, intermittently. It affects multiple different reports we have. It affects one particular report more frequently than other reports. Once a report is affected the same error will often appear in multiple reports at approximately the same time eg. for the next 10 minutes.The same report run with the same parameters may work when run again (soon after) or the application may need restarting before the report can be successfully re run. These reports all worked previously without issue. No change in server or code seems apparent which would have precipitated this error. All code behind for this is VB.NET We have had difficulty reproducing it in test environments and upgrading to the latest version of Crystal has not helped at all.

I am preparing crystal reports using vb.net 2008 with ms sql server 2005.everything is showing fine.. except that i want my report to be multiple column... I cant do this using "format multiple column" option because the data is not shown in details section. Actually i need to group the data in data.

e.g: i am preparing a warehouse report to know how much quantity of which products are left, products with 0 (zero) value are not displayed..

I want my reports to be as follows: item1 item_quantity item2 item_quantity item3 item_quantity

Adding A Reports Application Or A Crystal Reports Application?

I'm using VS 2008 to develop a solution which will report on data mostly contained in SQL Express databases, across two servers. It will be used by up to about 10 XP clients.

.net - Unable To Use Crystal Reports In Asp.net?

May 14, 2009

I have created reports using Crystal Reports in my asp.net application(vb). It was fine. But when I run it in another system, the report loading fails. So I modified my code like this.

sub Loadreport()
try
Dim sreport as new ReportDocument
sreport.Load(Server.MapPath("ClientList.rpt"))

[code]....

When the control comes to the line:-

sreport.Load(Server.MapPath("ClientList.rpt"))

it jumps to the catch block showing "Invalid Report path". But initially, the code was not showing any error. I haven't changed the path.

.net 2008 And Crystal Reports 10?

Mar 29, 2011

I made a program in VB .net 2008 that has a form in which there is a Crystal Report Viewer object. Here is some code:

[Code]...

1. Some reports show tens and hundreds of thousands or records (they are required to do so, so no work-around is possible), thus the time it takes for the Crystal Report Viewer control to actually show the report is very long. I would like to display like a waiting dialog window WHILE the report is loading its records telling the user to wait for it to load.

2. Another idea would be to show the number of records currently loaded (and continuously updated as the report loads them) from the total number. This is actually shown in my reports when i open them with Crystal Reports 10, but NOT with the Viewer control on the form! How can i make it show this?
