You can issue components from inventory to jobs and repetitive schedules and return issued components from jobs and schedules to inventory using the WIP Material Transactions window. There are two issue and return options available from this window: All Material and Specific Component.

Push and Pull Components
You can issue and return both push and pull components. You can ’push’ components from inventory to specific job and repetitive schedule operations. A component’s supply type determines how it is supplied to a job or schedule.

Negative Component Issues and Returns
You can issue components to satisfy negative job and schedule requirements. When you issue negative requirement components, the components are returned from the job or schedule to inventory. You can reverse negative component issues with negative component returns. When you return components that have negative requirements, the components are issued from inventory to the job or repetitive schedule.

Negative Inventory Balances
You can set the Allow Negative Balances Parameter in Oracle Inventory so that the inventory balances of items can be driven negative. If this parameter is set, a warning message is displayed to notify you that balances are about to be driven negative. You can continue with the transaction or stop it and fix the condition.

Requirement Quantities
You can issue partial requirement quantities. You can also over–issue requirements. Material that is required, but not issued, is considered an open requirement.

Ad Hoc Requirements
You can issue and return components that do not appear as job or schedule material requirements using the ’Specific Component’ option. When you issue or return components using this option, the system determines if the item is a material requirement for the job or schedule. If the item is not a material requirement, is a backflush component, or is not required at the operation sequence a warning message is displayed, but you can continue with the transaction. Components added in this manner are commonly referred to as ’ad hoc’ components.

Bulk, Supplier, and Phantom Components
You can issue Bulk, Supplier, and Phantom supply type items, which do not normally appear as requirements in the WIP Material Transactions window, using the ’Specific Component’ option.

Serial Number Validations
You can issue and return component items that are under lot, serial number, or both lot and serial number control. Available serial number records are restricted for use when issuing a serialized item, returning it to stock, and then to a different job. At the time of completion, serialized components are available from stock if they have the following values set in the Serial Numbers window in Oracle Inventory:

performing the component return or negative component issue.
