When you enter material transactions in the WIP Material Transactions window you must select one of the following transaction types:

 

Definitions

• Component Pick Release You can select component requirements to issue to jobs and schedules on the Component Pick Release window. This window generates move orders. You can select items for discrete jobs, lot based jobs, repetitive schedules, and flow schedules. Each manufacturing mode has a distinct and individual window. You can also use a rules based system to determine a recommended source location for each component.
• Replenishment transaction (Backflush transferl) is a material transaction to stage components in advance of backflushing. This ensures that materials are available for backflush transactions.
• Backflush (op pull/assembly pull) is a material transaction to issue component items from inventory to work in process.
• Comp. Issue transaction (push) is a material transaction to issue component items from inventory to work in process.
  
• Job Completion Completing the WIP job and moving the finished good to the FG sub inventory.
  
• Assembly Return Returing the finished good from FG back into the To Move operation on assembly line.
• Comp. Return transaction is a material transaction to return components from WIP back to inventory. Return transactions increase WIP material requirements, inventory balances, and valuation, and decrease WIP valuation.

2 - Replenishment supply subinventory     
Replenishes the supply subinventories of Operation Pull or Assembly Pull supply type components. You can transfer components from a 'source' subinventory/locator to the supply subinventory/locator associated with the component specified. If you replenish components under lot, serial, or lot and serial number control, you must identify the lots and/or serial numbers that are used to replenish the supply subinventory/locator.
    This transaction is similar to a subinventory transfer in Oracle Inventory.
4.1 – WIP Component Issue
WIP valuation Dr @Cost of Raw Mat
                                Inv valuation Cr @Cost of Raw Mat.
Issue components from inventory to jobs to fulfill positive material requirements.
(If you issue components under lot, serial, or lot and serial number control, you must identify which lots and/or serial numbers to issue)

4.2 – WIP Neg Comp Issue
Issues components from jobs to inventory to fulfill negative material requirements.  When you issue components that have negative requirements, components are returned from the job to inventory. (If you return components under lot, serial, or lot and serial number control, you must identify the lots and/or serial numbers to return) Negative material requirements allow you to recover by–products from your manufacturing processes. 
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.  For example, if you add negative material requirements to a non–standard discrete job that is tracking the disassembly of a completed assembly, 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.

7.1 – WIP Component Return
WIP component returns reverse WIP component issues. (If you return components under lot, serial, or serial number control, you must identify the lots and/or serial numbers to return) 

7.2 – WIP Neg Component Return
WIP negative component returns reverse WIP negative component issues. When you return components that have negative requirements, components are issued from inventory to the job. (If you issue components that are under lot, serial, or lot and serial number control, you must identify the lots and/or serial numbers to issue)  Negative material requirements allow you to recover by–products from your manufacturing processes.
