How the numbering of documents is controlled in the Purchasing Module?

Purchasing allows the same document number to be used by different operating units. It can be automatic (system created ;only numeric ) or manual (user puts the number ;can be numeric or alpha numeric )


What are the types of Purchase Orders? How do they differ from each other?

1) Standard Purchase order for one time purchase 2)Blanket Purchase Agreements for specific type of items from a buyer over period 3) Blanket Releases actual purchase order4) You create contract purchase agreements with your suppliers to agree on specific terms and conditions without indicating the goods and services 5) A planned purchase order is a long–term agreement committing to buy items or services from a single source.


What is meant by Line Types in PO Module? What are the different value basis available for Line Types?

Line Types is feature in PO to differentiate order for goods from those for amount based services or outside processing.Line types can be quantity based ,amount based


What is meant by RFQ? How the suppliers are attached to the RFQ?

Request for quotation; Suppliers are attached to the RFQ by pressing the suppliers button in the RFQ screen and entering the names of the suppliers.


Can the material be returned to the supplier? Can we return the material to the receiving area? Can the system create Debit Note for the returned material?

1) Material can be returned to supplier 2) To return items to receiving, enter the return quantity in the ReceivingReturns window. If you originally performed a direct receipt, you must specify a Return To receiving location. 3) The system can create debit notes for the returned material if the ‘Create Debit Memo from RTS transaction’ check box for the supplier site is checked.


What is supplier item catalog? How it is used?

1) The Supplier Item Catalog provides a simple mechanism for locating items and their source information for the purpose of creating purchase order and requisition lines.2) You can open the catalog from an existing requisition or purchase order and add lines to that document. Alternatively, you can open the catalog from the Navigator and search for item information from there.


Can a requisition be amended?

It can be updated befor approval.It can not be updated after approval.It can be cancelled.


Which documents in Purchasing use the approval hierarchy?

Requisition & Purchase Order


Which documents in Purchasing can be autocreated?

standard purchase orders, planned purchase ,orders, blanket releases, and RFQs can be auto created.


What is quotation? How it is approved? Can the quotation line be approved individually?

A quotation is the supplier’s response to that RFQ.By using Approve quotation window & providing approval type & reason quotation can be approved.Line can be approved individually.


In which tables the RFQ & Quotation information stored?



What is revision no. in Purchase Order?

The revision no in PO is changed no which starts at 0 & increaments by 1 when you change the control information.One type of document can have multiple revision no.


Can we reference the requisition no. in PO? How the link between PO & Requisition is maintained?



Can we receive material without reference to PO and Supplier?

We can receive material without reference to PO by recording Unordered Receipt but the supplier name is reqd. to be specified.


Can we correct the receipt of material recorded by changing the quantity?

Yes. The quantity can be changed

Yes. The supplier header info. is shared across the operating units.


Where is the currency for the invoices and payments to the supplier specified?

It is specified in the Payment Tab of the supplier site info



Sr. No




What is item master Organization?

Items are defined in one organization. To distinguish it from others, we call it the Item Master organization. Other organizations (child organizations) refer to the Item Master for item definition.There is no functional or technical difference between the Item Master organization and other organizations.It is for simplicity & central maintenance.


What is a Sub-Inventory?

Subinventories are unique physical or logical separations of material. All material within an organization is held in a subinventory therefore, inventory, such as raw inventory, finished goods, or defective material. you must define at least one subinventory.


what is Category & category set?

A category is a logical classification of items that have similar characteristics. A category set is a distinct grouping scheme and consists of categories.Category sets group your categories into functional areas,such as inventory, cost, purchasing, order entry etc.You can use categories and category sets to group your items for various reports and programs.


What is a Stock Locators?

Locators are required to identify physical areas where the inventory items are stored.(rack/bin or aisle/row/bin locations.) Item quantities can be tracked by locator. Items can also be restricted to specific locators.


What is difference between Available Qty & On-hand Qty?

Available Quantity is the quantity available to transfer, based on the unit of measure specified. The available quantity is the quantity on hand less all reservations for the item (and minus pending transactions).On hand Quantity is the current on–hand quantity for the item, based on the unit of measure specified.


What are Item Templates?

An Item template is a defined set of attribute values.(you can use templates over and over to create many similar items.) When you apply a template to an item, you overlay or default in the set of attribute values to the item definition.


What is the purpose of organization Assignment?

After defining an item in the Item Master it has to be assigned to the organizations and is known as organization assignment.The purpose of of organization assignment is to make the item available for transactions in a particular organization.


Mention any 5 attributes of an Item?

Transactable,Purchasable,Stockable,Costing Enabled and Inventory Item,Restrict Subinventories,Serial Number Control.


Explain the features of Move Order.

Move orders are requests for the movement of material within a single organization.Move orders allow to distinguish between inventory management processes and the actual material transaction process.Move orders are created for purposes like replenishment, material storage relocations, and quality handling.


What is the importance of UOM.

Units of measure are defined to track, move, store, and count the items. Each item in Oracle Inventory must have a primary unit of measure.And also each transaction must have a unit of measure associated with the transaction quantity.


What are Transaction types?

A transaction types are combination of a transaction source type and a transaction action. They are used to classify a particular transaction for reporting and querying purposes. (A transaction source type is the type of entity against which Oracle Inventory charges a transaction like account, move order, sales order, inventory,RMA ;A transaction action is a generic type of material movement or cost update with no specificity regarding the source of the transaction like issue from store, assembly return etc)


Explain any two actions linked with transaction types?

The actions used to define transactions are 1)Receipt into stores,2)Issue from stores,3)Subinventory transfer4)Physical inventory adjustment


What are item cross references used for?

Cross–reference types define relationships between items and entities such as old item numbers or supplier item numbers.For example, you can create a cross–reference type Old to track the old item numbers, and a type Supplier to track supplier part numbers.


What is the effect of the following transactions on On-hand Qty ? A) Sub inventory Transfer B) Miscellaneous issues.

The On-hand Qty remains the same on a Sub inventory Transfer. The On-hand Qty reduces on Miscellaneous issues.

BOM: Bill of Materials


Standard BOM:A standard bill of material is the most common type of bill and lists the mandatory components,

the required quantity of each component, and information to control work in process, material planning, and other

Oracle Manufacturing functions. Examples include bills for manufacturing assemblies, pick-to-order bills, kit bills, and phantoms.

Model BOM :A model bill of material defines the list of options and option classes you can choose in Oracle Order Management

to order a configuration. A model bill also specifies mandatory components or included items that are required

for each configuration of that model

It is a Bill of material where component items are specific to that model.

Option class Bom : It is a bill of material for an option class item that contains a list of related options.

Planning BOM: A planning bill of material is a bill of material structure that includes a percentage distribution for its components.

Engineering BOM:

Primary Bill of material

A primary bill is a list of components thar are most frequently used to build a product.

The primary bill is the default for rolling up costs, defining a job, and calculating cumulative item lead times

Alternate Bill

An alternate bill is another list of components used to build a same product.

Supply types

Assembly Pull

Assembly Pullcomponents are issued to discrete jobs and repetitive schedules when you complete assemblies in Work in Process.

They are pulled from the supply subinventory assigned to the component requirement.

Operation Pull

Operation pull components are issued to discrete jobs and repetitive schedules when you complete backflush operations.

Components are pulled the supply subinventory assigned to the component


Push components can be issued directly to discrete jobs and repetitive schedule as required. You can specify the subinventory

from which to issue push components, though Work in Process defaults the supply subinventory associated with the component.


Supplier component requirements can be included on bills of material. Requirements for supplier components are created

when you define discrete jobs and repetitive schedules in Work in Process.

Supplier components are not backflushed nor do they default when issuing all components for an assembly. You can, however,

manually issue specific supplier components to discrete jobs and repetitive schedules


Bulk component requirements can be viewed and are displayed on reports. They can be used to communicate to the shop floor

that bulk components must be used but need not be transacted.



Use resources to define the time an assembly spends at an operation and the cost you incur at the operation. A resource is

anything you require to perform, schedule, or cost, including but not limited to: employees, machines, outside processing services,

and physical space. A resource and usage rate for all scheduled activities is required in a routing. Scheduled resources can

include queue, setup, run, and move time.

UOM: Unit of measure that describes how you measure resource.

Charge types

You can determine how each resource is charged in Work in Process. When an operation completes, Work in Process records the

units applied to the job or repetitive schedule in the resource unit of measure. You can charge resources manually or automatically.

Manual: Work in Process does not automatically charge this type of resource to a job or repetitive schedule. You must

manually charge it to a job or repetitive schedule using Work in Process

PO Receipt: Automatically charge this resource upon receipt of a purchase order in Oracle Purchasing. The assemblies are

not automatically moved to the next operation upon receipt, so you must manually move them using Work in Process

PO Move: Automatically charge this resource upon receipt of a purchase order in Oracle Purchasing and move the assemblies

to the Queue intraoperation step of the next operation, or to the To move intraoperation step if this is the last operation.

WIP Move: Work in Process automatically charges this type of resource to a job or repetitive schedule when you complete

an operation.

Basis type by which to charge and schedule the resource.

Item: Charge and schedule the resource where the resource usage quantity is the amount required per assembly unit you make.

Lot: Charge and schedule the resource where the resource usage quantity is the amount required per job or schedule.


Primary Routing:

A primary routing is the list of operations most frequently performed to build a product

Alternative Routing

An alternate routing is a different manufacturing process used to produce the same product.


A department is an area within your organization that consists of one or more people, machines, or suppliers, where you want to

collect costs, apply overhead, and compare load to capacity. You assign a department to each operation in a routing, and

assign resources that are available for that department.

Department Class

Use department classes to group departments for shop floor scheduling and control, and to identify manufacturing cells

and flexible machine centers. Department classes are used for reporting purposes.

Count points and Auto charge

You can define which operations in a routing record move transactions by defining how resources are consumed at that operation.

The Count Point and Autocharge check boxes work together. In the following discussion, the Count Point and Autocharge

check boxes can be set to either on or off. However, you cannot set Count Point on and Autocharge off.

When you move assemblies from an operation with Count Point on / Autocharge on operation to another count point operation

set the same way, Work in Process automatically completes all Count Point off / Autocharge on count point operations between them.

Count Point off / Autocharge on

Assign this count point to operations that you always perform in a routing, but where you do not want to monitor assembly moves into,

out of, and through the operation. For example, choose this count point for non-bottleneck operations that are not labor or

time-intensive, such as inspection or minor assembly operations.

Work in Process automatically completes the operation and charges its WIP move resources to your job or schedule when you

record a move transaction through or beyond the operation, as with Count Point on / Autocharge on count point operations

Count Point off / Autocharge off

Assign this count point to operations that you do not typically perform in a routing. For example, a rework operation that you only

perform on occasion. If you choose this count point for an operation, Work in Process does not complete the operation and

charge its resources to your job or schedule unless you explicitly record a move transaction into and through the operation.

Work in Process does not default the operation. You can still record movements into, out of, and through the operation by overriding

the default in Work in Process.

Count Point on / Autocharge on

Assign this count point to operations you want to automatically default as destination operations in the Move Transactions window.

You should always assign this count point to the final operation in a routing, to insure that you record move transactions into

the operation, and then record completion transactions.

You can automatically complete and charge operations in a routing with this count point. Work in Process automatically completes

an operation and charges its WIP Move resources to your job or schedule when you record a move transaction through

or beyond the operation.

For operations that you always perform in a routing, you can also monitor assembly moves into, out of, and through the operation.

For example, choose this count point for critical, time-intensive, or bottleneck operations.

Standard Operation

A standard operation is a commonly used operation that you define as a template to default operation information

when you define routings.

Backflushing Transactions

You can specify at what point in the routing you backflush component material. Moves automatically backflush the

appropriate components at the time they are needed.

Operation Pull Backflush Transactions

Operation pull backflush transactions automatically pull inventory for all Operation Pull components defined at the operation.

They also pulls components for all non-backflush operations between the current operation and the last completed backflush operation.

Whether the backflush occurs automatically during a move transaction is determined by the whether the operation is or

is not defined as a backflush operation

Assembly Pull Backflush Transactions

When you complete an assembly that has Assembly Pull components, these components are automatically pulled (backflushed)

from their assigned supply subinventories/locators

If the components being backflushed are under manual lot control, serial control, or lot and serial control, you must enter lot and/or

serial numbers. If the job is tied to one or more sales orders, the system automatically completes the assembly for those orders
