Pivot Dinamico y Filas con Texto

Aqui dejo una posible respuestal, la cual me esta funcionando, solo es una variante de lo de arriba, pero jala bien.

Código:

DECLARE @Names NVARCHAR(MAX)
SET  @Names =''
SELECT @Names = @Names + '[' + Nombre + '],'
    FROM         (SELECT DISTINCT Usuarios.User_Name AS Nombre
        FROM Ticket_Approvals INNER JOIN
                      Usuarios ON Ticket_Approvals.Ticket_Approval_By = Usuarios.User_ID
        WHERE      Ticket_ID = 3) dd

--PRINT @GroupBy
--print LEN(@Names)

IF (LEN(@Names)>0)
    BEGIN
        SET @Names = LEFT(@Names, LEN(@Names) -1)
        EXEC ('SELECT *
                FROM (SELECT Ticket_Detail_ID, Usuarios.User_Name As Nombre, 
                        Ticket_Detail_Status + ' + ''' - ''' + ' + Ticket_Approval_Reason As Status 
                        FROM Ticket_Approvals INNER JOIN Usuarios ON Ticket_Approvals.Ticket_Approval_By = Usuarios.User_ID
                        WHERE Ticket_ID= 3 GROUP BY Ticket_Approvals.Ticket_Detail_ID, 
                                            Usuarios.User_Name, 
                        Ticket_Approvals.Ticket_Detail_Status + ' + ''' - ''' + ' + Ticket_Approvals.Ticket_Approval_Reason) pvt 
            PIVOT (Max([Status]) FOR [Nombre] IN (' + @Names + ')) AS Child
            GROUP BY Ticket_Detail_ID, ' + @Names)
    END
