A site is a store, a distribution center or a production location. In SAP Retail, the site is the organizational level at which merchandise replenishment is planned and stocks are managed.

A store is assigned one purchasing organization and one sales area (sales organization, distribution channel and division) and thereby also a distribution chain, to which the store belongs and which is used primarily for intercompany billing purposes. The store must be authorized to receive goods from the sales area to which the supplying distribution center belongs. If it is to be possible for merchandise to be transferred from one store to another, then the recipient store must also be authorized to receive goods from the sales area to which the supplying store belongs.

Each distribution center is assigned a purchasing organization (and, if required, a sales area) for determining warehouse transfer prices and units of measure.

A distribution center can also be assigned to a site (normally to itself) and a distribution chain (for determining sales prices). These assignments enable merchandise in the distribution center to be valuated at retail prices. This sort of valuation is most common in the apparel industry.

Each site belongs to exactly one company code.
