Procurement Cycle :
A brief introduction of Procurement activities is given below:
| Procurement Activities | Description |
|---|
| Determination of requirement | It is the logical subdivision where it is determined that what material or services are required to company, and which supplier can fulfill the requirement. |

Procurement for Stock vs Consumption
The following points show the difference of Procurement for Stock vs. Consumption:
Procurement for Stock - A stock material is a material that is kept in stock. These materials are kept in stock once received from the vendor. The stock of this material keeps on increasing or decreasing based on amount of the quantity received or issued. To order a material for stock, the material must have a master record within the system.
Procurement for Direct Consumption - When procurement is for direct consumption i.e. it will be consumed as soon as it is received, the user should specify the consumption purpose. To order a material for consumption, the material may have a master record within the system.
Special Procurement :
Consignment Stocks
Material that is available at our store premises, however it still belongs to the vendor (seller)/Owner of the material. If you utilize the material from consignment stocks, then you have to pay to the vendor.
Third-party processing
In third-party processing, a company passes on a sales order to associate external vendor (seller) who sends the goods directly to the customer. The sales order is not processed by your company, however by the vendor (seller). Third-party items can be entered in purchase requisitions, purchase orders and sales orders.
Pipeline handling
In pipeline handling, the company needs not to order or store the material involved. It is obtainable as and when required via a pipeline (for example, oil or water), or another style of cable (such as electricity). The material that is consumed is settled with the vendor (seller) on a regular basis.
Returnable Transport Stock
The company orders goods from a vendor (seller). The goods are delivered with returnable transport packaging (pallets, containers) that belongs to the vendor (seller) and is stored on the customer premises until they return it to the company.
Subcontracting
The vendor (the subcontractor) receives components from the ordering party with the help of which it produces a product. The product is ordered by your company through a purchase order. The components required by the vendor (seller) to manufacture the ordered product are listed in the purchase order and provided to the subcontractor.
Stock transfer using stock transport order
Goods are procured and supplied within a company. One plant order the goods internally from another plant (receiving plant/issuing plant). The goods are procured with a special type of purchase order - the stock transport order. You'll be able to request and monitor the transfer of goods with a stock transport order.
