[RESOLVED] Composite Table Issues - Does not match table definition

[BrailleSchool]

Hi, all,

I have a composite table called TicketAuthors that has four columns. Three of those are set to primary key. I have found that you can't have a NULL value with a composite table with multiple primary keys.
The issue I am having is that I am using a stored procedure to check to see if the name exists, if it doesn't, then to add the name.

Only problem is, I am getting the error in the attached screen shot.
I have found that the table is removing the identity specification for two of the three primary key columns.
I am not sure what to do about this as this is the first time I am working with a composite primary key.
I have been searching for hours for a resolution and haven't found one yet.

Stored Procedure:

ALTER PROCEDURE dbo.CheckTicketAuthorExists(@User VARCHAR(250))
AS
BEGIN
IF (SELECT COUNT(*) FROM TicketAuthors WHERE TicketAuthors = @User) = 0
BEGIN
INSERT INTO TicketAuthors
VALUES(@User)
END
END

Table setup:

CREATE TABLE [dbo].[TicketAuthors](
	[CreatedByID_PK] [int] NOT NULL,
	[LastModifiedByID_PK] [int] NOT NULL,
	[BeingViewedByID_PK] [int] IDENTITY(1,1) NOT NULL,
	[TicketAuthors] [varchar](250) NOT NULL,
 CONSTRAINT [PK_TicketAuthors] PRIMARY KEY CLUSTERED 
(
	[CreatedByID_PK] ASC,
	[LastModifiedByID_PK] ASC,
	[BeingViewedByID_PK] ASC
)WITH (PAD_INDEX  = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]

All the three public key columns need to have the same value. Please advise as to your thoughts on how to get this working.
