Position of the Topic in the Complete Training Scenario

The figure illustrates the position of sales order handling in the complete process flow.
Scenario
Sales orders are the central documents to record demand of wholesale customers in order to allow for procurement, customer delivery and billing.
In SAP S/4HANA for fashion and vertical business you will record seasonal demand e.g. the actual collections of sport shoes in all required color and size variants.
In SAP S/4HANA for fashion and vertical business you need all sales related fashion master data to be available in the sales order.
The sales order might be created manually by a sales representative, in the call center, or it might be received via an interface directly from customers, a B2B or a B2C platform.
B2B = Business to Business. Selling bulk quantities to wholesale customers
B2C = Business to Consumer. Selling to individuals. Typically small quantities.

Sales orders in SAP can be used for a variety of business cases.
Sales orders have been enhanced for Fashion and Vertical Business in order to support the usage of fashion-specific master data and special functionality
Transaction VA01 is the main transaction to create sales orders.
Customizing for sales orders can be found primarily in IMG → Sales and Distribution → Sales → Sales Documents and then by
