This filter option uses the data in the last auxiliary Boolean attribute field for orders to
determine which orders are to be filtered out. You can check the values for our tutorial
system by opening the Attributes window and going to the last field in the Order tab. An
entry of Null, 0 (zero), or False means that the order will not be filtered out, or that it will
be included in the performance metrics. An entry of 1 or True means that the order will
not be included in the performance metrics.
In our tutorial system, we entered False for all orders that are end items—orders that have
a bill of materials level code of zero. We entered True for all other orders. We then
activated the order filter option. This means that our performance metrics will only
include the 33 end item or customer orders.
Since we need our orders to be completed on time, we have also changed our early and
late tolerance times. All our orders are due at 11
PM , so we changed our Early Tolerance
time to 16 hours and our Late Tolerance time to zero hours, as shown above.
Forward scheduling
Let’s start with the schedule we generated in the previous chapter using the Sequence >
Forward > By Release Date menu option. We will assume this to be our base schedule
case and will generate alternate schedules on the board to compare against it. Once we
have our base case, we’ll define it as our base by selecting the Performance > Set As
Baseline menu option. This temporarily saves a set of performance measures for the
current schedule. You can view these performance measures by selecting the
Performance > Baseline Comparison menu option. The upper portion of the resulting
Baseline Comparison window is shown below.
