Document numbers are used to identify store and sales operations, and can be entered manually or generated automatically.

Document number formats are used for automatic generation of document numbers. They contain a database query which is used to retrieve data on the basis of which document numbers are generated.

Document number formats are managed in the Number generators directory.

The directory contains a number of predefined document number formats that are system objects and cannot be edited. They can, however, be used as templates for creating your own document number formats.
