Overview of Model/Unit Number Effectivity

You can control the effectivity of changes to bills of material and routings with model/unit number effectivity. When you specify a model/unit number as the effectivity, you can enter a particular change for a specific deliverable end item. The change can be effective for that item and all subsequently produced items, for only one model/unit number of the product family, or for a contiguous block of model/unit numbers. This technique does not use date to control effectivity and therefore provides a convenient way to specify engineering changes for products requiring a long lead time. This change can occur at any level in the bill of material structure of the end item.

Model/unit effectivity provides many versions of the same end item part number. A model/unit number consists of the alphanumeric prefix for the model/unit number of the end item followed by the specific item number.

Note: Model/unit numbers are unique across organizations.

Note: If you want to issue material across unit numbers, you must select the Allow Cross Unit Number Issues parameter in the Project Manufacturing Parameters window.

Model/Unit Number Effectivity Example

The following figure demonstrates the use of model/unit effectivity to define item configurations. In the following figures, shaded boxes for items F-90 Jet 10-101, Exhaust Nozzle 20-101, Control System 30-101, and Fan Frame 30-103 represent a model/unit effective item. All other items are date effective.

You can define components of a model/unit effective item to be effective for a single model/unit number (for example, Fan Casing1 40-301), or defined to be effective for a range of model/unit numbers (for example, Fan Casing2 40-302)

Note the following in the above bill of material definition:

1. Model/unit effective items can have date effective items or other model/unit effective items as components. For example, F-90 Jet (10-101), has both date effective (20-102 and 20-103) and model/unit effective (20-101) items as its components.

2. All components in the bill of a model/unit effective item must be effective for a single model/unit number or for a range of model/unit numbers. This is also true for date effective components of model/unit effective assemblies. For example, even though Core (20-102) is a date effective item, you must specify a model/unit number when the item appears on the bill of a model/unit effective parent, F-90 Jet (10-101). Although components for a (sub)assembly could be comprised of date effective items, you would still need to define their unit effectivity if the (sub)assembly is unit effective.

3. Bills for date effective assemblies cannot have unit effective components and you cannot enter model/unit effectivity on these bills. For example, Rotor Assembly (40-303) is a date effective component in the bill of model/unit effective item Fan Frame (30-103). The bill of Rotor Assembly can have only date effective items as its components and you cannot specify model/unit numbers on the bill.

Explosion of an end item with a specific unit number yields different configurations of the same end item.

The following figure shows the configuration for F-90 Jet (Item Number 10-101) with a model/unit number F90-01.

Note: Only those model/unit number items with an 01 in their effective range are included.

Similarly for a model/unit Number of F90-06, the configuration are as shown in the following figure.

Generating Model/Unit Numbers

Use the Generate Model/Unit Numbers window to define and generate model or unit numbers associated with a specific end item number.

Note: Only those model/unit number items with an 06 in their effective range are included.

Before generating model/unit numbers, you should do the following:

• Install Oracle Project Manufacturing

• Set up Project Organization Parameters

To generate model unit numbers

1. Navigate to the Generate Model/Unit Numbers window.

   

2. Enter the following parameters:

   • Select the item number.

     • Enter the Prefix.

     • Enter the Start number.

     • Enter the Count, or quantity of numbers needed.

     • Enter the Numeric Width or number of digits for each item number.

3. Choose Submit.

Use the End Item Model/Unit Number windows to view and define new model/unit numbers. You can add or modify comments only on previously defined model/unit numbers.

To view or modify model/unit numbers

1. Navigate to the End Item Model/Unit Numbers window.

   

2. Select an end item.

3. View or enter the following:

   • End Item Model

     • Unit Number

     • Comment

4. Save your work.
