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 will be set to Forward Scheduling.
• The Earliest Start Date field in the Shop Order window will be updated according to the material availability. If all material lines of the shop order is fully reserved/issued, the ESD 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.
