Understanding Attachment of Part Lists
You attach the parts list after you enter a work order or rate schedule header. A parts list is a table of the components and their quantities required to complete the work order. You can attach the parts list using any of these methods:
Manually, by entering the required parts on the Work Order Parts List form (W3111A).
Interactively, by copying a bill of material or an existing parts list on a work order.
Batch, using the Order Processing program (R31410).
Automatically, by setting a processing option for the Work Order Routing Instructions program (P3112) after you attach routing instructions using the work order entry program.
(Release 9.2 Update) Automatically, by calling a version of the Order Processing program (R31410) at the time of work order creation.
For batch bills and batch routings, the system determines which parts list to use by matching the quantity for the bill type that is specified on the work order header. (Use a batch bill to accommodate physical constraints, such as ovens or vats, in industries in which products are produced in fixed quantities. Use batch routings in industries such as pharmaceuticals, foods, or petroleum, in which products are manufactured in fixed quantities or batches.) If the system does not find a batch size that matches the parts list, it uses this search sequence to locate a matching batch:
Searches for the specified bill type with a zero batch quantity.
Searches for a type M bill with the specified quantity.
Searches for a type M bill with a zero batch quantity.
If the system does not find a match, it does not attach a parts list, and you must attach the parts list manually.
Based on their effective dates, components are included in or excluded from the parts list for a work order. The system increases the quantity of each component by its scrap factor and operation scrap, if applicable.
These terms are used throughout the work order examples that follow:
- Shrink
The planned loss of a parent item caused by factors such as breakage, theft, deterioration, and evaporation.
- Scrap
Unusable material that results from the production process. Scrap is material outside of specifications and of such characteristics that rework is impractical.
- Yield
The ratio of usable output from a process to its input.
These examples illustrate several scenarios pertaining to shrink, scrap, and operational yield for components of parent item A. Each example is based on a quantity of 10 for Parent Item A.
This example illustrates a work order with no shrink, scrap, or yield:
