Is It Possible That DTS Skipped Indentity Attribut

I imported a table using DTS.
I run SQL statements in my original server database. It works well.
But when I run the same instructions within a stored procedure in my new workstation where I improrted the table I get this error:
Server: Msg 515, Level 16, State 2, Procedure InsertFichierPrix, Line 11
Cannot insert the value NULL into column 'Id', table 'myDBLive.dbo.FichierPrix'; column does not allow nulls. INSERT fails.
The statement has been terminated.

Here is the SQL statements that I run on the original Database:

insert into fichierprix(nomfichier, version, descriptionfr, typeclient,....) values(@NomFichier,'Actuelle', @NomFourFr, 'MembreAcheteur', ....)


And here is my SP that I run on the new imported database:

CREATE PROCEDURE InsertFichierPrix @NomFichier varchar(50), @NomFr varchar(50),@NomAn varchar(50)
AS

declare @NomFourFr varchar(50)
declare @NomFourAn varchar(50)

SET @NomFourFr='liste fournisseur ' + @NomFr
set @NomFourAn='liste fournisseur ' + @NomAn

insert into fichierprix(nomfichier, version, descriptionfr, typeclient,...) values(@NomFichier,'Actuelle', @NomFourFr, 'MembreAcheteur'...)

GO

And here is the execution of my Stored proc on the destination database:

execute insertfichierprix @NomFichier='myfilename2', @NomFr='fournifr1',@NomAn='Fourniang1'


Thank you for helping me.
