Purchase Requisition
A requisition order is a form that a department must submit to whichever department controls the financial activities of the business. Although individual forms vary by business, requisition orders generally require certain information, including the department requesting materials, the exact number of supplies requested, a general description of those supplies, the legal name of the supplier and the expected price of the purchase. A requisition order is either approved or denied by the financial department of the business.

Purchase Order
Once the financial office of a business has approved the requisition order submitted by a department, it issues a purchase order to the supplier of the requested goods. Purchase orders should include certain information, such as the name of the purchasing office, supplies being purchased, ship-to address, payment terms, invoicing instructions and purchase order number. To assist in record keeping, purchase orders will have the same number as the requisition order that generated them.
Account Assignment
Some Purchase Orders can have Account Assignment. They are assigned to give information on who to bill internally. Some examples are
If a PO is assigned Cost Center under Account assignment, then for that PO Cost center is billed(?)
If a PO is assigned Sales Document , that means , the PO was created to satisfy a Sales Order. This is valid in the case, where a company buys some items from 3rd Party vendors and then sells them to their clients.
