Some features in sales order processing are common to all sales documents. For example, you can use the fast change feature in any sales document, regardless of type (it can be a sales order, quotation, contract, and so on) to change certain data (for example, the plant, billing block or reason for rejection) for several items at once.
Another example of a common feature is the incompletion log, which reminds you automatically if important data is missing when you save a document.
