Answer 1

Define Reasons for Ordering
In this step, you define possible reasons for ordering. These describe why a purchase order was placed. You can enter the reason for ordering in the item data when creating or maintaining a purchase order. The "reason for ordering" can also be used to document the reason for returning goods if the item in question is a returns item.
Example
A typical reason for the creation of a purchase order may be "New business contact following attendance at a trade fair". Returns may be due to suppliers recalling parts or quality deficiencies you have discovered yourself.
Activities
1. Check which reasons for ordering are likely to occur in your enterprise.
2. If you wish to define new reasons, enter an alphanumeric key of max. three characters in length plus a short description.
======================================================================================================
Define Reasons for Cancellation
In this step, you can specify the circumstances under which a purchase order with a validity period (i.e., in the standard system, a PO of the document type 'FO') is terminated prematurely.
Activities
Define a key and enter a description of the relevant reasons for cancellation.
Example - if some one purposely cancels order, it can be tracked so that no one does it and only authorised officials can cancel orders in case of emergency.
======================================================================================================
Set Up Authorization Check for G/L Accounts
In this step, you set up the authorization check for G/L accounts in the case of purchase orders and scheduling agreements.
You can determine whether or not the authorization check is to be active for each company code.
If the check is active, each time a G/L account is entered in a PO or a scheduling agreement, the system checks whether the user has the posting authorization for the specified account.
Activities
Make the desired settings.
Mainly for Authorisation for GL.
====================================================================================================
Set Up Subcontract Order
For the supply of the input materials to be provided to the vendor (subcontractor) with respect to subcontract purchase orders, you have the option of creating an SD delivery from the list of stocks for a subcontractor.
In this step, you can specify a delivery type for the delivery of materials to be provided to the subcontractor.
If you make no settings here, in the standard system the delivery type "LB" is used. This means that you need make no further settings in order to use the functionality.
If you wish to set up new delivery types, you must extend all the relevant settings in SD Customizing for the delivery.
