The period of time for which an article is listed for an assortment is called a listing window. The maximum time span of the window is defined by:

• Valid-from date of the article

• Deletion date of the article

Within this maximum time span, you can create smaller time frames by manually creating listings through module item maintenance, or through automatic listing by entering the listing time frames

The listing window defines the availability of an article for certain functions in an assortment and therefore in the assortment users (such as a retail site) assigned to the assortment. In a site, the listing window defines when merchandise listed can be ordered. Purchase orders can only be generated if their planned delivery date falls within the period defined by the listing window.

If SD sales orders or deliveries are linked to the SAP Retail listing check function and the assortments are assigned to customers, the listing window also defines in these sales documents whether or not a customer can order an article.
