In order to modify the properties of an LU6.1 session, you must call KC_MODIFY_OBJECT with the object type KC_LSES.
For an LU6.1 session you can initiate connection establishment or connection cleardown and, in the case of connection establishment, assign a transport connection to the session.
If you request the immediate establishment of a connection, the QUIET property must not be set and the LPAP partner must not be disabled. If you request the immediate cleardown of a connection, none of the other properties must be modified.
When specifying a transport connection for the session, you should ensure that the connection exists and is generated for the associated LPAP partner.
Any changes you make to an LSES object do not take effect unless the utilization level of the application permits it.
