assignment of sales organization to purchasing organization

Hi experts,

I saw one diagram that shows a sales organization can be assigned to purchasing organization. Can you please tell me how to assign this? Here's the statement from a book.

In SAP Retail, a sales organization can be assigned to a purchasing organization. This

means that the hierarchy creation that is displayed in the figure may be enforced. For

statistical purposes, this may be of interest. In some cases, both terms are identical.

Thanks for the help
