By-Product Recovery
You can create negative material requirements to support the recovery of by-products and other reuseable or recoverable components. Negative requirements are supplied instead of consumed by jobs and schedules. For example, if you add negative material requirements to a non-standard discrete job that is tracking the disassembly of a completed part, the job supplies component materials rather than consuming them. Negative requirements are considered supply by the MRP planning process.
You can define negative requirement usage quantities when you assign components to bills of material in Oracle Bills of Material. Negative requirements can be assigned to lot, serial number, and lot and serial number controlled items.
