Net Work in Process

When you choose to net WIP, the planning process considers work in process standard and non-standard discrete jobs and repetitive schedules as scheduled receipts (supply).

If you do not choose to net WIP, the planning process ignores work in process standard and non-standard discrete jobs and repetitive schedules, regardless of MRP netting information defined on these entities. The calculation of WIP supply and demand is affected by several attributes defined on the discrete job.

Standard Discrete Jobs

Assembly supplies and component demands from standard discrete jobs with the following statuses are included:

Non-Standard Discrete Jobs

A non-standard discrete job controls material and collects costs for miscellaneous manufacturing activities.

For example, these manufacturing activities may include activities with no defined standards, such as items without a bill of material and routing. These miscellaneous activities can include rework, field service repair, engineering projects, and tool or machine creation/maintenance.

Repetitive Schedules

Since Oracle Master Scheduling/MRP and Supply Chain Planning uses different planning algorithms for repetitive manufacturing, repetitive schedule statuses do not impact how repetitive schedule supplies and demands are viewed.

Assembly supplies and component demands from non-standard discrete jobs with the following statuses are included:

Since a non-standard discrete job is created manually and does not explode a bill of material, it does not automatically create material requirements. However, you can manually create material requirements with the WIP Material Transactions window. Oracle Master Scheduling/MRP and Supply Chain Planning recognizes only these requirements.

Attention: The planning process does not recommend rescheduling of existing non-standard jobs.

MRP Net Quantity

In Oracle Work in Process, you can specify an MRP net quantity for the standard and non-standard discrete jobs. The net quantity may differ from the job quantity for many reasons.

For example, you would set the net quantity to zero if you receive the discrete job quantity into a non-nettable completion subinventory.

When you choose to net WIP, the planning process uses the MRP net quantity on the order header to calculate available supply. See: Defining Discrete Jobs Manually.

MRP Net Component

At the component level, you can enter a value for the MRP Net field to establish if the planning process should net the requirement when calculating component demand. You may choose to enter No for a particular component if it is issued from a non-nettable subinventory.

When you choose to net WIP, the planning process uses the MRP net value at the component level to determine if the component requirement is included as demand.

Supplier Components

If you specify a WIP supply type of supplier for an item or component, the planning process ignores the requirement.

Negative Requirements

You can define negative usages for component items on a bill of material in Oracle Bills of Material. You can add negative requirements (byproducts) to discrete jobs using Oracle Work in Process. See: Byproduct Recovery.

Oracle Master Scheduling/MRP and Oracle Supply Chain Planning includes negative requirements on standard and non-standard discrete jobs and components with a negative usage on a bill of material when netting supply and demand. Oracle Master Scheduling/MRP and Oracle Supply Chain Planning considers this type of component requirement as supply available on the job completion date.

Note: You can manually add a negative requirement to a non-standard job in Oracle Work in Process to manage components that result in disassembly. You could use this option for repairing assembly units. It allows you to track the item that is issued to the job as available supply on completion of the repair job. See: Component Issues and Returns and WIP Material Transaction Types.
