If you choose to select a different version of this routing the version selection screen only displays those versions that are available for use on the scheduled start date. The list includes those versions with an exception date that matches the start date. You can, however, view all versions of the selected routing via the Routing Management (GESROU) function. The operations used for the selected version of the routing are loaded automatically (if permitted for the release mode defined in the header information). If you change the routing version to comply with a change to the production start date the routing operations are reloaded accordingly.
