    Check the Transaction code ME21N.

    Hi Hari,

     

    A purchase order is a formal request or instruction from a purchasing organization to a vendor or a plant to supply or provide a certain quantity of goods or services at or by a certain point in time.

     

    A purchase order (PO) consists of a document header and a number of items.

     

    Steps :

     

    1. Account Assignment - Costs can be apportioned among various Controlling objects

    via the account assignment.

     

    2. Vendor Confirmations - Vendors can issue confirmations to the relevant purchasing

    organization indicating their compliance or non-compliance with scheduled delivery

    dates.

     

    3. PO History - The transactions following on from a purchase order are documented in

    the PO history on an item-specific basis.

     

    4. Partner Roles - Instead of the vendor as the order recipient, other business partners

    can appear in various partner roles (e.g. goods supplier or invoicing party).

     

    5. Plant - In the purchase order, each item is destined for a certain plant. Each plant

    belongs to a company code, to which the vendor’s (creditor’s) invoice is directed.

     

    6. Texts - You can enter text in a purchase order directly or change texts that are

    suggested by the system. There are two kinds of text:

     

    a) Header text: applies to the entire document

    b) Item text: applies only to the relevant item.

     

     

    Transaction Code for Po creation is ME21N.

     

    In ME21N, You must Enter the Item, Material, Quantity, Delivery date, order unit, currency, vendor and pur. Group and so on.
