How Work Order Material Availability Rules and Assignments Work Together

You can prioritize the work orders in your manufacturing organization for release to the shop floor based on certain parameters like availability of materials. Use the Work Execution work area in Oracle Manufacturing to create rules to assign materials to the work orders in your organization, and execute work orders based on the assignment priority sequence.

Note: In the Setup and Maintenance work area, you must set up your organization as a manufacturing plant or a contract manufacturing organization using the Manage Inventory Organizations task by specifying the Manage Inventory Organization parameters.

Material Availability Rules

In the Work Execution work area, select the Material Availability Rules task from the Manage Production section in the Tasks panel.

Create a set of rules and recommend a list of work orders based on those rules to assign and unassign materials to work orders of higher priority. Your recommendations determine which work orders are prioritized when materials are scarce or unavailable.

Perform the various actions to create a set of material availability rules in the following three tabs:

Work Order Assignment Priority: Assign a rule sequence to various attributes of a work order such as work order type, scheduled start date, customer, and so on. The list can be also be sorted in an ascending or descending order based on attributes like planned start date or planned completion date of work orders.

The following table lists all the attributes that you can use to define the work order assignment priority and their corresponding descriptions:

Attribute	Description
Item	It represents the work order output item, which is an assembly item.
Item Category	Name of the category that's used to group items for specific purposes such as reporting, usage, and so forth.
User Item Type	Indicator or classification for an item, such as finished or purchased.
Work Order Status	Current status (includes predefined and user-defined) of the work order during the manufacturing lifecycle.
Work Order Type	Classification of the nature of work being performed for standard, nonstandard, rework, and transform work orders.
Work Order Subtype	Attribute representing the specific nature of work being performed, such as standard production, prototyping, or repair
Work Order Priority	Attribute defined by the user to represent the priority of work order execution.
Planned Start Date	Date on which a work order is planned to start.
Planned Completion Date	Date on which a work order is planned to be complete.
Customer	Name of a customer for whom the product is being manufactured. In this case the work order is reserved as supply for a sales order.
Ship-to Country	Name of the country to which the final product will be shipped.
Scheduled Ship Date	Date on which the product is scheduled for shipment.

Inclusion Criteria: Include work orders or materials in the assignment criteria based on specific attributes such as work orders within a specified time fence or materials of a specific supply type scale.

The following table lists the key criteria values based on which you can create the material availability inclusion criteria.

Attribute	Description	Default Value
Work Order Date Type	Select the type of date criteria on the basis of which you want to classify work orders.	Start Date
Time Span	Specify the number of hours from the current time that you want to be considered for material availability calculations.	48 hours
Work Order Status	Select the type of status (includes predefined and user-defined) based on which you would like to plan for the work orders that must be included in material calculations.	Released, Unreleased
Work Order Type	Select the type based on which you would like to plan for the work orders that must be included in material calculations.	Standard
Work Order Subtype	Select the subtype based on which you would like to plan for the work orders that must be included in material calculations.	All
Component Supply Type	Select the supply type of the materials which you want to plan availability for.	All
Build in WIP Items	Check box you must select to determine whether or not to include in material calculations the component items that are internally manufactured.	Yes

Forced Assignment Criteria: Manually adjust the material assignment criteria by creating a list of work orders for which materials can't be unassigned during material availability calculations.

Note: The attributes that you can use to define the forced assignment criteria are the same as the attributes you use to create the work order assignment priority.

Material Availability Assignments

In the Work Execution work area, select the Material Availability Assignments task from the Manage Production section in the Tasks panel.

You can calculate material availability considering or without considering substitutes. You must click Calculate Material Availability or Calculate Material Availability with Substitutes to initiate the background process which will create the list of work orders and their corresponding assignment sequence based on the rules you have earlier defined.

You can view the list of work orders to which materials are assigned based on the rules you create and the applicable assignment criteria. You can also view the material availability indicator to understand if materials are completely assigned, partially assigned, or not assigned to a work order considering or without considering substitutes. You can accept substitute recommendation and also view assignment details to preview expected supplies of materials.

You can view the work orders and material assignment in the workbench in the following tabs:

Work Orders: View all work orders in your manufacturing organization with their assigned prioritization sequence based on the rules that were enforced.
Materials: View a list of all materials that are included in material availability calculations based on the inclusion criteria.

After you have assessed the assignment priority of the work orders and reassigned materials to work orders based on expected supplies of materials in the workbench, you can either release work orders or place work orders on hold. You can select work orders individually to change their status or select the Mass Action drop-down list and change the status of a set of work orders.
