Oracle E-Business Suite Work in Progress(WIP) Concept | Class-18


  1. What are the differences between standard and non-standard discrete jobs?Non-standard jobs are similar to standard jobs, however, there are noteworthy differences including:

    • Non-standard jobs are more flexible than standard jobs. Because of this they can be used to manage such varying activities as rework, field service repair, upgrades, disassembly, maintenance, engineering prototypes, and other miscellaneous projects.

    • Oracle planning products do not create planned orders or reschedule recommendations for non-standard jobs. You must manually define and reschedule non-standard jobs. However, if a non-standard job is assigned an assembly bill of material, a routing, or both, planning considers the job’s material requirements as demand and its assemblies as supply.

    • Oracle planning products do not deduct scrapped assemblies from the MRP net quantity, or deduct the MRP net quantity by the item shrinkage rate for non-standard jobs. As such, you must identify planned assembly shrinkage by entering an MRP net quantity that is less than the job quantity.

    2. What is the difference between Discrete and Repetitive manufacturing?

    Standard discrete jobs control the material, resources, and operations required to build an assembly and collect its manufacturing cost.

    Non-standard discrete jobs control material and collect costs for miscellaneous manufacturing activity. They may or may not build an assembly. This type of activity can include rework, field service repair, upgrade, disassembly, maintenance, engineering prototypes, and other projects.

    3. What is the purpose of using WIP accounting class?

    Standard discrete accounting classes can be used to group job costs. For example, if you build subassemblies and finished goods, you can define your accounting classes so that you can separately value and report the costs associated with subassembly and finished goods production. Standard discrete accounting classes can be automatically defaulted when you create discrete jobs.

    4. What is back flushing?

    When you complete assemblies, all components with the supply type of Assembly pull are automatically backflushed. When components for assemblies under lot control, serial number control, or lot and serial control are backflushed upon assembly completion, you must assign lot and/or serial numbers to the components.

    Backflush components are issued in the quantity and item as defined on the bill of material.

    5. What would be scenario if the Discrete job on which OSP operation exists is closed before the receipt of OSP item?

    If Discrete job which has OSP operation is closed before receipt of the OSP item, then the resource transaction would cost this transaction would error out.

    Typically, system warns the user when user tries to close such discrete jobs.

    6. What is the criteria system checks when linking Sales order to Discrete job?

    When linking ATO sales orders and jobs, however, the following rules are applied:

    • Assembly item cannot be a Pick-to-order item
    • Sales order line item must be demanded, but not yet shipped
    • Assembly item must be a standard item or an ATO item, not a model or an option

    7. What is Outside processing? What are the modules involved in OSP?

    Oracle Manufacturing enables you to include supplier-sourced components and resources in your manufacturing processes. Features include:

    • Using specialized supplier skills in your manufacturing process to help lower engineering and manufacturing costs and increase production quality

    • Using supplier capacity to increase your overall production capacity.

    Outside processing items represent supplier-sourced items, resources, and services that you include in your build process. These items can be non-stocked items which represent the actual supplier contribution in your build process or you can define the assembly itself as an outside processing item. The outside processing item is the item on your requisition or purchase order and the item you receive in your purchase order receipts.Modules involved are Inventory, Purchasing and WIP

    8. What is the difference between Detailed Scheduling and Dynamic lead-time offsetting?

    WIP Scheduling uses routing details for calculation job/operation start and end dates. This is called “Detailed Scheduling”.If you are using MRP/ASCP, Dynamic lead time offsetting is the scheduling method used and it uses the Fixed and Variable lead time defined in Item master.

    9. If OSP requisition needs to be generated at the time of move transaction to that particular operation then what are the setups required for handling this scenario?

    In WIP parameters form, specify Requisition creation time as At Operation.

  2. Client wants to track the value of transactions that is being scrapped during an operation, what are the setups required to handle this scenario?In WIP parameters form, specify one of the inter-operations steps as Scrap and Require Scrap account is checked.


  1. What is the purpose of Auto-implement Manager?Auto-Implement Manager runs at the specified dates and times and automatically implements items whose schedule dates occur on or before the current date. Engineering change orders or revised items whose status is scheduled are automatically implemented.

    2. What is a prototype?

    Engineering enables you to create engineering items, bills of material and routings the same way you define manufacturing item information. Each item defined in Engineering is assigned to engineering. You can define engineering items and assign item attribute details as you do for manufacturing items.

    3. What is Use-up date?

    The use-up date is the date when on-hand quantity is exhausted based on projected gross requirements. It calculates the use-up date by applying any on-hand quantity in inventory (supply) against any gross requirements (demand).

    4. How is ECO lifecycle being maintained in EBS?
    Engineering uses two ECO status fields to control the ECO life cycle: ECO Status and ECO Approval Status. You can open, hold, release, schedule, implement, or cancel a revised item or an ECO. Engineering does not let you set the ECO Status field to Implemented or Scheduled if the approval status has not been set to Approved.

    5. What is the purpose of Approval Lists?

    You can define lists of approvers required to approve an ECO before it can be released. Oracle Engineering notifies the people on the list, using an alert, that the ECO requires their approval.
