13.1 Introduction

Order Entry was designed to require minimal maintenance. All of the transaction files of Order Entry are designed to never need re-organization. The only maintenance required of Order Entry is periodic deletion of orders and packing slips.

Before an order can be deleted, all of the packing slips that make reference to the order must be deleted. Before a packing slip can be deleted, it must be shipped and billed. This implies that only shipped and billed orders are deleted.
