Autoincrement UDT in Stored Procedure

Question

Hi all,
I am tring to fill a UDT with a Stored Procedure.
The UDT is created in SBO.
I can't get find a way to fill the code and name columns.
Now I am trying via this Stored Procedure:
CREATE    PROCEDURE LeverFacturen
               @Datum as DateTIME= null --you can default it to null so that--if no date was passed then use today
     , @Eigens as varchar (1)
        AS
SET NOCOUNT ON
--if no date was passed in then use today's date (at 00:00:00)
if @Datum is null
     set @Datum = dateAdd(day, datediff(day,0,getdate()), 0)
        BEGIN
INSERT [@OIFLEFACT] (code,[name], U_CardCode, U_Docnum, U_LineNum,U_ItemCode,U_OIFIDGR, U_DocEntry, U_CardName, U_OIFPRRC, U_Project,U_OIFLOC)
SELECT DISTINCT (select max(code)+1 FROM  [dbo].[@OIFLEFACT]),(select max(code)+1 FROM  [dbo].[@OIFLEFACT]) as 'name', T0.cardcode,T0.DocNum,T1.LineNum, T1.ItemCode, T1.U_OIFIDGRP,T0.DocEntry,  T0.cardName, T1.U_OIFPRRC, T1.Project, T1.U_OIFLOC  
FROM ODLN T0 INNER JOIN DLN1 T1 ON T0.DocEntry = T1.DocEntry INNER JOIN OINS T2 ON T0.DocNum = T2.deliveryNo 
WHERE T0.DocNum in
(SELECT DISTINCT T0.deliveryNo FROM OINS T0 WHERE ((T0.U_OIFEDRI > @Datum) OR (T0.U_OIFEDRI IS NULL)) AND T0.U_OIFSDRI < @Datum) 
AND   T1.LineNum <> (SELECT  T1.BaseLinNum FROM OSRI T0  INNER JOIN SRI1 T1 ON T0.SysSerial = T1.SysSerial
WHERE T1.ItemCode =  T2.itemCode  AND T0.IntrSerial = T2.internalSN AND T1.BaseNum = T2.deliveryNo) 
AND T1.U_OIFPRRC > 0 AND  T2.U_OIFEQST  = 1
AND T2.customer IN  ( SELECT T0.CardCode FROM OCRD T0 WHERE  T0.QryGroup19 = @Eigens)
AND T0.Comments NOT LIKE 'Periodiek%%' order by T0.cardcode,t0.DocNum,T1.LineNum, T1.ItemCode, T1.U_OIFIDGRP
end
GO
But it tells me
"Violation of PRIMARY KEY constraint 'KOIFLEFACT_PRIMARY'"
I also tried with max(code). 
Probably the table is not yet updated.
Does anybody have a hint, or solved this in another way?
Cheers,

Solved.
What I did (solution not fit for very large sets):
CREATE     PROCEDURE sp_procname
     @variable AS VARCHAR(15),
        AS
SET NOCOUNT ON
DECLARE @id INTEGER
BEGIN
DECLARE BufferCursor CURSOR FOR
SELECT XXXXXX
END
OPEN BufferCursor
   FETCH NEXT FROM BufferCursor
      INTO @U_UDFs
   WHILE (@@FETCH_STATUS=0)
BEGIN    
  BEGIN
     SET @id = (SELECT max(code) FROM [dbo].[@UDT])
  END
     IF @id = NULL
         SELECT @code=0
      ELSE
         SELECT @code = @id +1
     INSERT INTO [dbo].[@UDT](code,[name], U_UDFs,..)
                 VALUES      (@code,@code, @U_UDFs,..)
      FETCH NEXT FROM BufferCursor
     INTO @U_UDFs
END
   CLOSE BufferCursor
   DEALLOCATE BufferCursor
GO
