    Many-to-many relationships allow a list to point to a list of entries, rather than to single field.

    If a knowledge base article points to a list of related configuration items, it uses a related list. Not all lists can be used as related lists, however. For a list to be related to another list, a many-to-many relationship that refers to both tables must exist.

    The Many to Many Definitions [sys_m2m] table allows administrators to create custom many-to-many relationships.

    Many-to-Many tables aren't considered custom tables and don't count toward your custom table allotment.
