Planned Work Orders

The planned work orders are exclusively created by the MRP procedure. They cannot be created directly.

The different data involved in this type of order can be modified. Furthermore, the order can be deleted. As a matter of fact, it is automatically erased when you launch a new MRP calculation.

For a work order involved in a project, the project number is displayed next to the order number.

Fields

Quantity:	Released quantity.
Release date:	Planned released date (and hour).
Due date:	Computed requirement date (and hour).
Priority:	Priority index which can be used in the finite capacity scheduling.
Transfer Batch:	Transfer batch size used for scheduling with overlapping.

When a planned order is modified, it is automatically scheduled again (to infinite capacity) and the component requirements are updated.

When a planned order is deleted, the requirements induced on the components are also deleted.

A planned order can be immediately transformed into a firm order (by the Firm W.O. button) with the possibility of modifying the dates or the quantity.

It is worth noting that it is possible to change a routing or a BOM even if they are associated to a planned WO.

Buttons

Firm WO	This button converts the planned work order into a firm work order. Then, it is eliminated from the list of the planned work orders.
Master Sch.	This button launches the infinite capacity scheduling for the order. One can schedule an order only if the work loads file already exists, i.e. if the scheduling and work load calculation function has already been launched (Planning menu).
Workloads	This button shows the Work Load Graph for the Work Order. This graph display the work load profile for the operation selected in the list calculated by the Infinite Scheduling and Work Load Calculation function.
Gantt	This button displays the Gantt chart that presents a forward schedule of the Work Order and a backward schedule. This diagram shows the three fundamental positions in time of the order : • according to the requirement dates (in black), • according to a forward schedule (in blue), • according to a backward schedule (in red).
Graph	This button posts the flow chart for the Work Order. This graph simultaneously displays the sequence of the operations for the work order, the quantities to produce on each work center, and the estimated rejects.
Change Routing	This button posts the routing lists that you can use for the item. If you select a routing, the software displays the active revision at the release. It requires a confirmation for the change in routing.
Change BOM Variant	This button posts the list of BOM variants for the item. If one selects a BOM variant different from that used by the MRP calculation, the requirements are updated.

This window presents three tabs:

• The first one displays the operations corresponding to the routing. When a line is clicked on, the Routing Operation Maintenance window is posted.

• The second shows the component requirement list. When a line in the list is clicked on, the Component Modification window is shown.

• The third one shows the order scheduling dates that have been computed by the Order scheduling and loads calculation function (Scheduling menu, finite capacity scheduling function) or by the Schedule button.
