It wil be superseeded by another part fo the schule of teh same job
i.e. if you have a full scheduled for Friday at 20:00
and daily incrementals schueld for every day at 20:00 (including on a Friday) then teh incremental on the Friday wil be listed as Superseeded because the full ran instead.
As a massive recommendation get onto a newer version than BE 2012 - especially for scheduling confusion issues - 2012 was the recipient of what is in effect version 1.0 of our new Scheduling and Job Management configuration - we received a lot of feedback (some from ex-BE2010 customers and some from new BE2012 customers) about this new design and changes were implemented in the BE 2014 release (and lat) that provided more usability and flexibility.
