Need assistance on my problem below...
Tables involved = 4 (tblUserData, tblDocuments, tblDocIssues, tblIssues)
Columns involved = 4.....(Doc #, Beg bates) from tblUserData, (Volume) from tblDocuments, and (IssueName) from tblIssues.

Code is below

Issue: I would like to group by Doc # or Beg bates but would like to have certain valuesfrom the multivalue field (IssueName) into an alias field called NOTES.
SELECT [Doc #], [Beg bates], Volume, [IssueName]
FROM (dbo.tblDocuments INNER JOIN dbo.tblUserData ON dbo.tblDocuments.DocGUID = dbo.tblUserData.MasterGUID) INNER JOIN (dbo.tblDocIssues INNER JOIN dbo.tblIssues ON dbo.tblDocIssues.IssueGUID = dbo.tblIssues.IssueGUID) ON dbo.tblUserData.MasterGUID = dbo.tblDocIssues.DocGUID
WHERE ([IssueName] = '02 - Not Responsive') OR ([IssueName] = '01 - Responsive') OR ([IssueName] = 'Group Tag Test') OR ([IssueName] = 'Privilege')
ORDER BY [Doc #]

First of all you have to create function for IssueName concatenation:

CREATE FUNCTION MyFceIssueConcat (@DocNr  varchar(100))
RETURNS varchar(1000)
AS
BEGIN
DECLARE @IssueNames  varchar(1000)
SELECT @IssueNames = COALESCE(@IssueNames + ',', '') + CAST([IssueName] AS varchar(100))
  FROM dbo.tblDocuments
  INNER JOIN dbo.tblUserData ON dbo.tblDocuments.DocGUID = dbo.tblUserData.MasterGUID
  INNER JOIN dbo.tblDocIssues ON dbo.tblUserData.MasterGUID = dbo.tblDocIssues.DocGUID
  INNER JOIN dbo.tblIssues ON dbo.tblDocIssues.IssueGUID = dbo.tblIssues.IssueGUID
 WHERE [Doc #] = @DocNr

RETURN @IssueNames  
END

And now you may use it in the query:

SELECT [Doc #], [Beg bates], Volume, MyFceIssueConcat([Doc #]) Notes
  FROM dbo.tblDocuments 
 INNER JOIN dbo.tblUserData ON dbo.tblDocuments.DocGUID = dbo.tblUserData.MasterGUID
 INNER JOIN dbo.tblDocIssues ON dbo.tblUserData.MasterGUID = dbo.tblDocIssues.DocGUID
 INNER JOIN dbo.tblIssues ON dbo.tblDocIssues.IssueGUID = dbo.tblIssues.IssueGUID
 WHERE [IssueName] IN ('02 - Not Responsive', '01 - Responsive', 'Group Tag Test', 'Privilege')
 GROUP BY [Doc #], [Beg bates], Volume
 ORDER BY [Doc #]

I get an error from your code
"Msg 195, Level 15, State 10, Line 1
'test' is not a recognized built-in function name."

Where is the 'test' word used in your code? Did you add it somewhere?

MyFceIssueConcat is used on two places. Did you change it on both?

The first place is the function creation, the second place is the query.

Ok..i was able to run your function and "Command(s) completed successfully" but i didn't want to modify anything.. Even so..I then re-ran the query you created after the function but the results are same

Msg 195, Level 15, State 10, Line 1
'MyFceIssueConcat' is not a recognized built-in function name.

SELECT [Doc #], [Beg bates], Volume, [IssueName]
FROM (dbo.tblDocuments INNER JOIN dbo.tblUserData ON dbo.tblDocuments.DocGUID = dbo.tblUserData.MasterGUID) INNER JOIN (dbo.tblDocIssues INNER JOIN dbo.tblIssues ON dbo.tblDocIssues.IssueGUID = dbo.tblIssues.IssueGUID) ON dbo.tblUserData.MasterGUID = dbo.tblDocIssues.DocGUID
WHERE ([IssueName] = '02 - Not Responsive') OR ([IssueName] = '01 - Responsive') OR ([IssueName] = 'Group Tag Test') OR ([IssueName] = 'Privilege')
ORDER BY [Doc #]

So, please change the function call to dbo.MyFceIssueConcat():
SELECT [Doc #], [Beg bates], Volume, dbo.MyFceIssueConcat([Doc #]) Notes
  FROM dbo.tblDocuments 
 INNER JOIN dbo.tblUserData ON dbo.tblDocuments.DocGUID = dbo.tblUserData.MasterGUID
 INNER JOIN dbo.tblDocIssues ON dbo.tblUserData.MasterGUID = dbo.tblDocIssues.DocGUID
 INNER JOIN dbo.tblIssues ON dbo.tblDocIssues.IssueGUID = dbo.tblIssues.IssueGUID
 WHERE [IssueName] IN ('02 - Not Responsive', '01 - Responsive', 'Group Tag Test', 'Privilege')
 GROUP BY [Doc #], [Beg bates], Volume
 ORDER BY [Doc #]

I didn't want all values of Issue names associated to a doc # concatenated into one column tho. I only wanted the values that i was initially searching for.

Oh yes, it is just a small change of the function:
ALTER FUNCTION dbo.MyFceIssueConcat (@DocNr  varchar(100))
RETURNS varchar(1000)
AS
BEGIN
DECLARE @IssueNames  varchar(1000)
SELECT @IssueNames = COALESCE(@IssueNames + ',', '') + CAST([IssueName] AS varchar(100))
  FROM dbo.tblDocuments 
  INNER JOIN dbo.tblUserData ON dbo.tblDocuments.DocGUID = dbo.tblUserData.MasterGUID
  INNER JOIN dbo.tblDocIssues ON dbo.tblUserData.MasterGUID = dbo.tblDocIssues.DocGUID
  INNER JOIN dbo.tblIssues ON dbo.tblDocIssues.IssueGUID = dbo.tblIssues.IssueGUID
 WHERE [Doc #] = @DocNr AND
       [IssueName] IN ('02 - Not Responsive', '01 - Responsive', 'Group Tag Test', 'Privilege')
 ORDER BY [IssueName]
 
RETURN @IssueNames  
END

Yes, you have to create functions for this approach. To remove you may simply use

DROP FUNCTION dbo.MyFceIssueConcat

Another possibility is to use FOR XML clause as mentioned here: http://weblogs.sqlteam.com/mladenp/archive/2007/06/01/60220.aspx
