Shelf space is represented as the height and position of the space. Its contents are not represented; therefore, shelf
space never constrains you with specific allocation of space.
Reservation colorization
In rack and asset views, space reservation is identified by a colorization of the affected space, whether it is in a
rack or another asset. The colorization appears as a blue-bordered box. A reservation is shown on a view for the
selected period of time and view aspect (front or back).
For example, if you are looking at the front of a rack, only reservations of front space are colorized. If you wish
to see space reservation on the back of the rack, flip the rack to see the back view.
All reservations that affect a contiguous space in a rack are represented as one colorization block with a single
outline. This block may be selected to show the properties of all the reservations that it includes. Component
reservations work the same as rack unit reservations.
Visualization of reservation removes
If you remove an asset in the future, the application visualizes it in the same manner as it would for adding an
asset in the future. When you select the reservation, the properties panel shows whether the reservation includes
an "add" or a "remove". Additions are shown with start dates, and removes are shown with end dates.
Removes that occur within the same project do not render reservations for removes that occur within the same
project as the asset addition. This is done in order to avoid a confusing display with excess data. If you create an
asset and remove it in the same project, no reservation is shown for that project.
If the visualized reservation contains past due project activity, the visualization is modified to reflect it.
Reservation roll-up
Reservations appear in the current view and project views, but not in historical views. Reservations are shown
for the selected view by accumulating all future project activity into contiguous blocks of space on the selected
assets. Project activity includes additions, moves and removes.
The illustration depicts a rack that has been selected by the user with a current state and four subsequent
projects. Each future project changes the assets in the rack. What the user sees for the rack as its current state is
an accumulation of all the activity of all the future projects.
Cumulative reservations
Cumulative reservation is the result of all reservation space occupation past the reference point, but does not
include a visualization of removes and moves. You cannot drop assets into reserved spaces. The drop target, a
green rectangle, only shows possible drop spots.
Manager reservation override
Managers can override reservations in current state. Reservations are visible but do not prevent a manager from
adding assets into the reserved space. If a manager adds an asset in a reserved space, the application puts the
affected reservation into a conflicted state resulting from the dual occupation of space in the future.
If two assets occupy the same space at the same time, the only option available is to delete the action in conflict.
The conflict is a part of the project that was forced into conflict and is visible with a color change in the
