BAM error: Failed to list permissions for BAM view – System.Data.SqlTypes.SqlNullValueException: Data is Null.

I just encountered an error using the BAM views. None of the BAM views could be opened and I got following error:

An unspecified error has occurred.

Use the navigation bar on the left to access Business Activity Monitoring views.
If the problem persists, contact your System Administrator.

BamError

Unfortunately, this error doesn’t give much information on what the problem exactly is…
So of course, the first thing I did next was to check the event viewer. This gave me 3 error messages.

Current User: STG\edncnextEXCEPTION:System.Web.Services.Protocols.SoapException: Internal Server Error.

Both of these errors doesn’t help out at all.

A third and final error message I found in the event viewer was:

Current User: Domain\edncnext

This message doesn’t exactly give a lot of information, but it was the only one with some info in what the underlying problem should be. It had something to do with the permissions on the BAM view.I was however certain that my account had the necessary rights on all BAM views.

Cause

After some investigating I found that the problem was that an account was removed from Active Directory, but still had some BAM permissions defined on it.

Solution

First of all you’ll need to determine what user defined in the SQL BAM tables that was deleted in Active Directory.
When you are aware which account has recently been deleted from Active directory this would be easy… however in my case I wasn’t aware that there were any accounts removed from active directory.
In this case you can use a simple query to find the missing account, as explained in this blog post on msdn

USE BAMPrimaryImport
GO
Select Name,SID,SUser_SName(SID) as UserAccount from sysusers
WHERE ISLogin = 1 AND issqluser = 0 AND isntuser = 1

this will list all DB roles and the third column displays the windows users (and groups) with the User name (or group name). This third column should not contain any null values.
Where the value null appears, should be the account(s) that were deleted in Active directory.

You can use a command prompt to check the user account with this command:

net user UserName /domain

this will result in an error as shown below.

Command

So this clearly is the account that was deleted from Active Directory.

Now then… how to remove this account from BAM?

In the msdn blog post I mentioned earlier are 2 methods of manually deleting the user account.
There is a much simpler way to achieve this by using following SQL query

REVOKE VIEW DEFINITION ON USER::[domain\user] TO [BAM_ManagementWS] AS [domain\user]
GO

this should be enough to get your BAM views working again!

A special thanks to the Sandro Pereira blog post on this issue, which helped me to solve the problem quite quickly.

    Thanks really works 🙂 but at the end we need to remove the account manually from SQL
