Before we change the Work Order quantity, let's first examine how
Event Fences fit into the equation. As you recall from the initial
definition, an Event Fence is a setting on the Item Site master specifying
the period of time, measured in days, within which Event notifications
related to the Item Site should be issued. Looking at the Item Site master
for Item BOQ-002, we see that the Event Fence is set to five ("5") days,
as shown below:
Given their measurement in days, Event Fences relate to the timing
of Events. You might ask, How does timing relate to Events? Well, if you
look at the complete list of Events found in Appendix A, Appendix A, you will see that the majority of Events are
tied to Sales Orders or Work Orders. Because Orders have definite due
dates and start dates, they are time-sensitive.
Let's return to our specific example now. Look back at the Work
Order we created for Item BOQ-002 in the example. The start date is
"01/09/2004". We recall that the Event Fence setting for Item BOQ-002 in
Warehouse EAST is five days. That means in terms of calendar days, the
Event Fence for this Work Order ranges over a period of five days from
01/05/2004 to 01/09/2004. If a system-defined Event occurs within this
Event Fence, and you are subscribed to that Event in the correct
Warehouse, you will receive notification that the Event has occurred. If
the Event occurs prior to the Event Fence, no notification will be
issued.
Now let's initiate the "WoQtyChanged" Event and track the results.
Today's date is 01/08/2004, so we are within the specified Event Fence for
the BOQ-002 Item Site. All we have to do is open the Change Work Order
Quantity screen, which is found in the Work Order Control Section of the
W/O Module. And as you can see in the example, we will change the original
Work Order quantity from 100 units to 75 units:
