If "Show Active" is selected, only the components (mode)
or parents (mode) that are active on the current date,
will be shown, if one of the following conditions exist:
The Link Status is equal to Active and the Effective
Date is less than or equal to the current date (the link has thus been
active in the structure since or earlier than the current date).
The Link Status is equal to Inactive but the Effective Date is greater
than the current date (the link is in- active in the structure but only
from a future date later than the current date).
Take note that when this mode is applied to a Project specific BOM,
the link status plays no role since all components are regarded to be
active since the applicable serial number range, rather than the status
code, governs the effectivity.
