This enhancement includes two customer functions that are initiated when a status in the shipment header is set or reset:

• 'EXIT_SAPLV56F_011' is called AFTER after the checks of the standard system are carried out, but BEFORE the activities of the standard system are started.
  Example: AFTER the authorization check as to whether the 'Planned' status may be set, but BEFORE the actual activities for this status (copying delivery data into the shipment and leg determination).
  You can include further checks here.
• 'EXIT_SAPLV56F_012' is called AFTER the activities of the standard system are started. You can manipulate the results of the standard system afterwards.

For more information, refer to the documentation for function modules
