Update ESD According to Material Availability
Explanation
This activity is used to update the earliest start date 
(ESD) according to the material availability. The calculation uses the shortage 
definition from visualizer when deciding what should be the new ESD. Orders will be qualified in the visualizer as 
Shortage if the orders 
which has insufficient lead time for some of the required materials are 
going to be 
ordered. When categorizing some shop orders as having material shortages, 
it could mean that there is no sufficient supplies to be used as component 
supply for the shop order due to the fact that they are already reserved or will be 
used for some other demand orders. During this calculation, requisitions will 
not be considered as supplies.
When there are many material lines, the calculation will decide the 
worse case out of all the material lines and set ESD for the shop order accordingly. 
The worst case (if no firm supplies exist) will be the lead time for the 
component.
Prerequisites
	- The shop order should not be in the
	Closed or Cancelled status.
System Effects
As a result of this activity:
	- The 
	Scheduling Direction

	availability.

	will be set to the current date. Past due orders will be moved to at least 
	current date, or later if all material cannot be made available on current 
	date.
- The shop order will be rescheduled.
- If the shop order is connected to a CBS site the earliest possible start time (EPST) 
	in the CBS server will be updated accordingly.
