Hi,
Plz check dis :
IF @transaction_type IN (N'A', N'U') AND
(@Object_type = N'2)
BEGIN
If EXISTS (SELECT T0.[U_Envsrtky ]
FROM OCRD T0
WHERE T0.[cardcdoe] = @list_of_cols_val_tab_del and T0.[U_Envsrtky ]  =  T0.[U_Envsrtky ])
Begin
SET @error = 14
SET @error_message = N'Same Sort key is not allowed'
End
END
