Document Item Texts 

Item-specific texts refer to the document items to which they are assigned. You can maintain a separate text for each document item.

The material sales text is an important item text, as it describes the material in more detail. In the standard version of the SAP System, it is copied automatically from a reference document or a sales and distribution text. As with all item texts, the material sales text can also be entered directly in the sales and distribution document.
