How You Reserve Materials for Work Orders in Manufacturing

All material reservations are performed in the Oracle Inventory Management. A work order is a demand placed on the warehouse to reserve and pick material similar to a sales order or a transfer order.

You can manage reservation for work order materials in inventory. You can search, create, edit, and delete reservations for work order materials.

Manage Reservations in Inventory

The Manage Reservations and Picks page in Inventory enables you to search reservations for work order demand. When you enable the plant parameter Allow reservations for work order materials for the organization, this page displays additional fields, such as Operation Sequence and Work Order Product. Work order product is the primary output on the work order.

With material picking, you can create picks for the work order demand. This feature lets you reserve material for work order demand. Using the search parameters, you can:

• Search for reservations for a work order number.

• Refine your search to look for reservations for a specific operation by entering the operation sequence number or the item.

• Look for reservations for a work order number by entering an organization or item, choosing the Demand Document Type as Work Order and entering the work order number in the Demand Document Number.

The Demand Document Number list of values displays work orders in Released and Unreleased status.

Reserve Materials Manually

You can reserve materials manually in the Create Reservations page in inventory. You can access this page from Oracle Manufacturing and from Inventory.

• In Manufacturing in the Manage Work Orders page, when you click the Reserve Materials Manually button corresponding to the work order number, the Create Reservations page opens. This retrieves all the eligible materials of a work order number and displays the reservation details corresponding to the material. You can select a specific work order material and create reservation for it.

• In the Inventory Management functional area, use the Manage Reservations and Picks task to access the Create Reservations page. The Demand Document Number value and the Operation Sequence value is displayed by default with the work order number when you access the Create Reservations page when you access this page through the work order from Manufacturing. The values of these fields aren't displayed by default when you access this page from inventory.

Reserve Materials Automatically

You can use the Reserve Automatically button to reserve the work order material to the on hand supply automatically. When on hand supply isn't available, you can reserve work order materials to sources other than on hand supply sources, such as Purchase Order, Requisition, Transfer Order, Transfer Order Return, and Work Order in the details section. You can reserve a work order material to on hand in a specific subinventory or locator. If you want to reserve specific serial numbers to a work order material, you can enter subinventory or locator, in case of a locator-controlled subinventory, and enter the specific serial numbers you want to reserve using the Record Serial Number Information button. For a lot-controlled material, you can reserve a specific lot number to a work order material.

Note: You can't delete a reservation for a work order when there are open picks associated to the reservation.

You can reserve materials automatically for materials of a project-based work order. The material that doesn't belong to any project is referred to as common material. You can control whether or not you can reserve common material instead of project material using the inventory attributes of an item.

The Allow User of Common Supplies attribute is dependent on the values of the Hard Pegging Level attribute. The behavior for this attribute is specified in the following table:

Hard Pegging Level	Allow User of Common Supplies	Expected Behavior
None	Null	Allows reservation of common inventory
No	No	Disallows reservation of common inventory
Project and Task Project Project Group	No	Allows reservation of common inventory

Honor Reservations

Pick release honors previously detailed reservations, which were created for work order materials. The detailed reservation, if created for subinventory, locator, lot number, serial number, project, and task number is honored by the material pick release process. As a result, the picks are created for work order materials as detailed during the manual reservation. The manual reservation is carried forward to the destination subinventory, if it's reservable.

If there are no prior reservations, pick release creates detailed reservations for work order materials on pick confirm if the destination subinventory is reservable. The reservations aren't created for work order materials when the destination subinventory isn't reservable.
