Setting field identity
The Identity tab is only available for integer field types and for user-defined types based on integer types. Using this tab you can create an identity column.
This option specifies that the new column is an identity column.
Specify the value used for the first row that is loaded into the table.
Specify the value added to the identity value of the previous row that is loaded.
Not for replication
This option allows you to specify that the Identity property should not be enabled when a replication agent modifies the table that contains the identity column.
NB: This operation is performed by dropping/recreating the table.
