Question

CR gives Error in Formula: "This field name is not known,ErrorKind

Asked by: RekhaShah

I am stuck here very badly and need your help desperately.
I have a VB.Net Desktop Application(visual studio 2005) which uses Crystal reports XI release 2.
When I run the application on my development machine, it runs fine, CR opens up without any problem.  If I Install on Users machine,  it runs fine if I log on as me. I have created a Test User. If I log on as Test User , the UI runs fine, it reads the data from SQL server, populates all the combo boxes and listboxes.But when I click on Report, CR gives me an error :  Error in Formula: "This field name is not known .   Detail : ErrorKind
I  know My installation package is good, my connection to database is good because If I log on , everything is ok. I think, there is a problem with security/permission issue with CR. But I cannot figure out where the problem is. Any help will be greatly appreciated.

FYI:I am using Reportviewer to load the report. Application is connected to  SQL server via OLEDB(ADO). When I created a report, I used OLE DB(ADO) To connect to SQL server and use the stored procedure. I have checked Integrated Security box on connection box of the crystal report.

Does the Test User have permissions to the database and the stored procedure?

Intergrated security means the logged on Windows user needs to have a SQL Account that uses the same password.  He also needs permissions to the stored procedure

same password as what?

 

by: mlmccPosted on 2009-11-04 at 22:02:51ID: 25747072

Sorry, had the wrong idea.  Is the database setup for Windows authentication?  If not then users have to log into the database.  

Integrated security means MS SQL authenticates any Windows user as valid.  That user needs permissions to the tables, views, and stored procedures.

The UI gets populated from SQL Server via Stored procedures. That means the TestUser has permissions. I am thinking that if CR has any security issue! Because I get an error when I click on Crystal Report button only.
I am wondering, if i can change the connection to SQL in CR - may be via DNS - ODBC!
I can not have user log on everytime he/she presses CR button!

 

by: mlmccPosted on 2009-11-05 at 10:05:53ID: 25752144

Did you give all users permissions to the report file, Crystal dlls, etc?

How are you pulling the data from the database?

How do you give permissions to the report file?
I have SQL connection string in my app. which uses my username and password(which I plan to change as soon as this works!

 

by: mlmccPosted on 2009-11-05 at 11:11:54ID: 25752804

That is why the SQL works.  It has the correct permissions.

It won't be the report file but that you control through Windows file permissions or directory permissions.

It sounds like the typical user doesn't have database permissions.

mlmcc

 

by: RekhaShahPosted on 2009-11-05 at 12:44:40ID: 25753804

If a typical user did not have database permissions, my UI  would not work. That is the problem I can not understand -  all my stored proc work to populate all the comboboxes and listboxes in UI. It breaks only whey they try to access the report!

 

by: mlmccPosted on 2009-11-05 at 13:00:14ID: 25753966

It would work since you are passng your login information in the connection string.  Crystal uses its own connection string not the one in the application.  Thus since you are using Integrated Security, Crystal tries to use the logged in user as the user for logging into the database.  If that user doesn't have permissions then you can't log in.
